GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Lesser General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License along
with this program; if not, write to the Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Lesser General
Public License instead of this License.

An AES (Rijndael) Implementation in C/C++ (as specified in FIPS-197)
====================================================================
Changes in this Version (16/04/2007)
====================================
These changes remove errors in the VC++ build files and add some
improvements in file naming consitency and portability. There are
no changes to overcome reported bugs in the code.
1. gen_tabs() has been renamed to aes_init() to better decribe its
function to those not familiar with AES internals.
2. via_ace.h has been renamed to aes_via_ace.h.
3. Minor changes have been made to aestab.h and aestab.c to enable
all the code to be compiled in either C or C++.
4. The code for detecting memory alignment in aesmdoes.c has been
simplified and a new routine has been added:
aes_test_alignment_detection()
to check that the aligment test is likely to be correct.
5. The addition of support for Structured Exception Handling (SEH)
to YASM (well done Peter and Michael!) has allowed the AMD64
x64 assembler code to be changed to comply with SEH requriements.
6. Corrections to build files (for win32 debug build).
Overview
========
This code implements AES for both 32 and 64 bit systems with optional
assembler support for x86 and AMD64/EM64T (but optimised for AMD64).
The basic AES source code files are as follows:
aes.h the header file needed to use AES in C
aescpp.h the header file required with to use AES in C++
aesopt.h the header file for setting options (and some common code)
aestab.h the header file for the AES table declaration
aescrypt.c the main C source code file for encryption and decryption
aeskey.c the main C source code file for the key schedule
aestab.c the main file for the AES tables
brg_types.h a header defining some standard types and DLL defines
brg_endian.h a header containing code to detect or define endianness
aes_x86_v1.asm x86 assembler (YASM) alternative to aescrypt.c using
large tables
aes_x86_v2.asm x86 assembler (YASM) alternative to aescrypt.c using
compressed tables
aes_amd64.asm AMD64 assembler (YASM) alternative to aescrypt.c using
compressed tables
In addition AES modes are implemented in the files:
aes_modes.c AES modes with optional support for VIA ACE detection and use
aes_via_ace.h the header file for VIA ACE support
Other associated files for testing and support are:
aesaux.h header for auxilliary routines for testsing
aesaux.c auxilliary routines for testsingt
aestst.h header file for setting the testing environment
rdtsc.h a header file that provides access to the Time Stamp Counter
aestst.c a simple test program for quick tests of the AES code
aesgav.c a program to generate and verify the test vector files
aesrav.c a program to verify output against the test vector files
aestmr.c a program to time the code on x86 systems
modetest.c a program to test the AES modes support
vbxam.doc a demonstration of AES DLL use from Visual Basic in Microsoft Word
vb.txt Visual Basic code from the above example (win32 only)
aesxam.c an example of AES use
tablegen.c a program to generate a simplified 'aestab.c' file for
use with compilers that find aestab.c too complex
yasm.rules the YASM build rules file for Microsoft Visual Studio 2005
via_ace.txt describes support for the VIA ACE cryptography engine

Building The AES Libraries
--------------------------
A. Versions
-----------
The code can be used to build static and dynamic libraries, each in five
versions:
C uses C source code only
ASM_X86_V1C large table x86 assembler code for encrypt/decrypt
ASM_X86_V2 compressed table x86 assembler for encrypt/decrypt and keying
ASM_X86_V2C compressed table x86 assembler code for encrypt/decrypt
ASM_AMD64 compressed table x86 assembler code for encrypt/decrypt
The C version can be compiled for Win32 or x64, the x86 assembler versions
are for Win32 only and the AMD64 version for x64 only.
B. Types
--------
The code makes use of types defined as uint_<nn>t where <nn> is the length
of the type, for example, the unsigned 32-bit type is 'uint_32t'. These are
NOT the same as the fixed width integer types in C99, inttypes.h and stdint.h
since several attempts to use these types have shown that support for them is
still highly variable. But a regular expression search and replace in VC++
with search on 'uint_{:z}t' and a replace with 'uint\1_t' will convert these
types to C99 types (there should be similar search/replace facilities on other
systems).
C. YASM
-------
If you wish to use the x86 assembler files you will also need the YASM open
source x86 assembler (r1331 or later) for Windows which can be obtained from:
http://www.tortall.net/projects/yasm/
This assembler should be placed in the bin directory used by VC++, which, for
Visual Stduio 2005, is typically:
C:\Program Files (x86)\Microsoft Visual Studio 8\VC\bin
You will also need to move the yasm.rules file from this distribution into
the directory where Visual Studio 2005 expects to find it, which is typically:
C:\Program Files (x86)\Microsoft Visual Studio 8\VC\VCProjectDefaults
Alternatively you can configure the path for rules files within Visual Studio.
D. Configuration
----------------
The following configurations are available as projects for Visual Studio 2005
but the following descriptions should allow them to be built in other x86

C source: aes_modes.c
x86 assembler: aes_amd64.asm
defines ASM_X86_V2 (set for C and assembler files)
dll_asm_amd64_c x64
headers: aes.h, aesopt.h, aestab.h, brg_endian.h, tdefs,h
C source: aes_modes.c
x86 assembler: aes_amd64.asm
defines DLL_EXPORT, ASM_AMD64_C (set for C and assembler files)
Notes:
ASM_X86_V1C is defined if using the version 1 assembler code (aescrypt1.asm).
The defines in the assember file must match those in aes.h and
aesopt.h). Also remember to include/exclude the right assembler
and C files in the build to avoid undefined or multiply defined
symbols - include aescrypt1.asm and exclude aescrypt.c and
aescrypt2.asm.
ASM_X86_V2 is defined if using the version 2 assembler code (aescrypt2.asm).
This version provides a full, self contained assembler version
and does not use any C source code files except for the mutiple
block encryption modes that are provided by aes_modes.c. The define
ASM_X86_V2 must be set on the YASM command line (or in aescrypt2.asm)
to use this version and all C files except aec_modes.c and. for the
DLL build, aestab.c must be excluded from the build.
ASM_X86_V2C is defined when using the version 2 assembler code (aescrypt2.asm)
with faster key scheduling provided by the in C code (the options in
the assember file must match those in aes.h and aesopt.h). In this
case aeskey.c and aestab.c are needed with aescrypt2.asm and the
define ASM_X86_V2C must be set for both the C files and for
asecrypt2.asm command lines (or in aesopt.h and aescrypt2.asm).
Include aescrypt2.asm aeskey.c and aestab.c, exclude aescrypt.c for
this option.
ASM_AMD64_C is defined when using the AMD64 assembly code because the C key
scheduling is sued in this case.
DLL_EXPORT must be defined to generate the DLL version of the code and
to run tests on it
DLL_IMPORT must be defined to use the DLL version of the code in an
application program
Directories the paths for the various directories for test vector input and
output have to be set in aestst.h
VIA ACE see the via_ace.txt for this item
Static The static libraries are named:
Libraries
aes_lib_generic_c.lib
aes_lib_asm_x86_v1c.lib
aes_lib_asm_x86_v2.lib
aes_lib_asm_x86_v2c.lib
aes_lib_asm_amd64_c.lib
and placed in one of the the directories:
lib\win32\release\
lib\win32\debug\
lib\x64\release\
lib\x64\debug\
in the aes root directory depending on the platform(win32 or
x64) and the build (release or debug). After any of these is
built it is then copied into aes.lib, which is the library
that is subsequently used for testing. Hence testing is for
the last static library built.
Dynamic The static libraries are named:
Libraries
aes_lib_generic_c.dll
aes_lib_asm_x86_v1c.dll
aes_lib_asm_x86_v2.dll
aes_lib_asm_x86_v2c.dll
aes_lib_asm_amd64_c.dll
and placed in one of the the directories:
dll\win32\release\
dll\win32\debug\
dll\x64\release\
dll\x64\debug\
in the aes root directory depending on the platform(win32 or
x64) and the build (release or debug). Each DLL library:
aes_<ext>.dll
has three associated files:
aes_dll_<ext>.lib the library file for implicit linking
aes_dll_<ext>.exp the exports file
aes_dll_<ext>.pdb the symbol file
After any DLL is built it and its three related files are then
copied into aes.lib, aes.lib, aes,exp and aes.pdb, which are
the libraries used for testing. Hence testing is for the last
static library or DLL built.
E. Testing
----------
These tests require that the test vector files are placed in the 'testvals'
subdirectory. If the AES Algorithm Validation Suite tests will be use3d then
the *.fax files need to be put in the 'testvals\fax' subdirectory. This is
covered in more detail below.
The projects test_dll and time_dll are used to test and time the last DLL
built. These use the files:
test_dll: Win32 (x64 for the C and AMD64 versions)
headers: aes.h, aescpp.h, brg_types.h, aesaux.h and aestst.h
C source: aesaux.c, aesrav.c
defines: DLL_IMPORT
time_dll: Win32 (x64 for the C and AMD64 versions)
headers: aes.h, aescpp.h, brg_types.h, aesaux.h aestst.h and rdtsc.h
C source: aesaux.c, aestmr.c
defines: DLL_IMPORT
and link to the DLL using explicit linking. However, if the lib file associated
with the DLL is linked into this project and the symbol DYNAMIC_LINK in aestst.h
is left undefined, then implicit linking will be used
The projects test_lib and time_lib are used to test and time the last static LIB
built. They use the files:
test_lib: Win32 (x64 for the C and AMD64 versions)
headers: aes.h, aescpp.h, brg_types.h, aesaux.h and aestst.h
C source: aesaux.c, aesrav.c
defines:
time_lib: Win32 (x64 for the C and AMD64 versions)
headers: aes.h, aescpp.h, brg_types.h, aesaux.h, aestst.h and rdtsc.h
C source: aesaux.c, aestmr.c
defines:
and link to the last static library built.
The above test take command line arguments that determine which test are run
as follows:
test_lib /t:[knec] /k:[468]
test_dll /t:[knec] /k:[468]
where the symbols in square brackets can be used in any combination (without
the brackets) and have the following meanings:
/t:[knec] selects which tests are used
/k:[468] selects the key lengths used
/c compares output with reference (see later)
k: generate ECB Known Answer Test files
n: generate ECB Known Answer Test files (new)
e: generate ECB Monte Carlo Test files
c: generate CBC Monte Carlo Test files
and the characters giving the lengths are digits representing the lengths in
32-bit units.\n\n");
The project test_modes tests the AES modes. It uses the files:
test_modes: Win32 or x64
headers: aes.h, aescpp.h, brg_types.h, aesaux,h and aestst.h
C source: aesaux.c, modetest.c
defines: none for static library test, DLL_IMPORT for DLL test
which again links to the last library built.
F. Other Applications
---------------------
These are:
gen_tests builds the test_vector files. The commad line is
gen_tests /t:knec /k:468 /c
as described earlier
test_aes_avs run the AES Algorithm Validation Suite tests for
ECB, CBC, CFB and OFB modes
gen_tables builds a simple version of aes_tab.c (in aestab2.c)
for compilers that cannot handle the normal version
aes_example provides an example of AES use
These applications are linked to the last static library built or, if
DLL_IMPORT is defined during compilation, to the last DLL built.
G. Use of the VIA ACE Cryptography Engine
-----------------------------------------
The use of the code with the VIA ACE cryptography engine in described in the
file via_ace.txt. In outline aes_modes.c is used and USE_VIA_ACE_IF_PRESENT
is defined either in section 2 of aesopt.h or as a compilation option in Visual
Studio. If in addition ASSUME_VIA_ACE_PRESENT is also defined then all normal
AES code will be removed if not needed to support VIA ACE use. If VIA ACE
support is needed and AES assembler is being used only the ASM_X86_V1C and
ASM_X86_V2C versions should be used since ASM_X86_V2 and ASM_AMD64 do not
support the VIA ACE engine.
H. The AES Test Vector Files
----------------------------
These files fall in the following groups (where <nn> is a two digit
number):
1. ecbvk<nn>.txt ECB vectors with variable key
2. ecbvt<nn>.txt ECB vectors with variable text
3. ecbnk<nn>.txt new ECB vectors with variable key
4. ecbnt<nn>.txt new ECB vectors with variable text
5. ecbme<nn>.txt ECB monte carlo encryption test vectors
6. ecbmd<nn>.txt ECB monte carlo decryption test vectors
7. cbcme<nn>.txt CBC monte carlo encryption test vectors
8. cbcmd<nn>.txt CBC monte carlo decryption test vectors
The first digit of the numeric suffix on the filename gives the block size
in 32 bit units and the second numeric digit gives the key size. For example,
the file ecbvk44.txt provides the test vectors for ECB encryption with a 128
bit block size and a 128 bit key size. The test routines expect to find these
files in the 'testvals' subdirectory within the aes root directory. The
'outvals' subdirectory is used for outputs that are compared with the files
in 'testvals'. Note that the monte carlo test vectors are the result of
applying AES iteratively 10000 times, not just once.
The AES Algorithm Validation Suite tests can be run for ECB, CBC, CFB and
OFB modes (CFB1 and CFB8 are not implemented). The test routine uses the
*.fax test files, which should be placed in the 'testvals\fax' subdirectory.
I. The Basic AES Calling Interface
----------------------------------
The basic AES code keeps its state in a context, there being different
contexts for encryption and decryption:
aes_encrypt_ctx
aes_decrypt_ctx
The AES code is initialised with the call
aes_init(void)
although this is only essential if the option to generate the AES tables at
run-time has been set in the options (i.e.fixed tables are not being used).
The AES encryption key is set by one of the calls:
aes_encrypt_key128(const unsigned char *key, aes_encrypt_ctx cx[1])
aes_encrypt_key192(const unsigned char *key, aes_encrypt_ctx cx[1])
aes_encrypt_key256(const unsigned char *key, aes_encrypt_ctx cx[1])
or by:
aes_encrypt_key(const unsigned char *key, int key_len,
aes_encrypt_ctx cx[1])
where the key length is set by 'key_len', which can be the length in bits
or bytes.
Similarly, the AES decryption key is set by one of:
aes_decrypt_key128(const unsigned char *key, aes_decrypt_ctx cx[1])
aes_decrypt_key192(const unsigned char *key, aes_decrypt_ctx cx[1])
aes_decrypt_key256(const unsigned char *key, aes_decrypt_ctx cx[1])
or by:
aes_decrypt_key(const unsigned char *key, int key_len,
aes_decrypt_ctx cx[1])
Encryption and decryption for a single 16 byte block is then achieved using:
aes_encrypt(const unsigned char *in, unsigned char *out,
const aes_encrypt_ctx cx[1])
aes_decrypt(const unsigned char *in, unsigned char *out,
const aes_decrypt_ctx cx[1])
The above subroutines return a value of EXIT_SUCCESS or EXIT_FAILURE
depending on whether the operation succeeded or failed.
J. The Calling Interface for the AES Modes
------------------------------------------
The subroutines for the AES modes, ECB, CBC, CFB, OFB and CTR, each process
blocks of variable length and can also be called several times to complete
single mode operations incrementally on long messages (or those messages,
not all of which are available at the same time). The calls:
aes_ecb_encrypt(const unsigned char *ibuf, unsigned char *obuf,
int len, const aes_encrypt_ctx cx[1])
aes_ecb_decrypt(const unsigned char *ibuf, unsigned char *obuf,
int len, const aes_decrypt_ctx cx[1])
for ECB operations and those for CBC:
aes_cbc_encrypt(const unsigned char *ibuf, unsigned char *obuf,
int len, unsigned char *iv, const aes_encrypt_ctx cx[1])
aes_cbc_decrypt(const unsigned char *ibuf, unsigned char *obuf,
int len, unsigned char *iv, const aes_decrypt_ctx cx[1])
can only process blocks whose lengths are multiples of 16 bytes but the calls
for CFB, OFB and CTR mode operations:
aes_cfb_encrypt(const unsigned char *ibuf, unsigned char *obuf,
int len, unsigned char *iv, aes_encrypt_ctx cx[1])
aes_cfb_decrypt(const unsigned char *ibuf, unsigned char *obuf,
int len, unsigned char *iv, aes_encrypt_ctx cx[1])
aes_ofb_encrypt(const unsigned char *ibuf, unsigned char *obuf,
int len, unsigned char *iv, aes_encrypt_ctx cx[1])
aes_ofb_decrypt(const unsigned char *ibuf, unsigned char *obuf,
int len, unsigned char *iv, aes_encrypt_ctx cx[1])
aes_ctr_encrypt(const unsigned char *ibuf, unsigned char *obuf,
int len, unsigned char *cbuf, cbuf_inc ctr_inc, aes_encrypt_ctx cx[1])
aes_ctr_decrypt(const unsigned char *ibuf, unsigned char *obuf,
int len, unsigned char *cbuf, cbuf_inc ctr_inc, aes_encrypt_ctx cx[1])
can process blocks of any length. Note also that CFB, OFB and CTR mode calls only
use AES encryption contexts even during decryption operations.
The calls CTR mode operations use a buffer (cbuf) which holds the counter value
together with a function parameter:
void cbuf_inc(unsigned char *cbuf);
that is ued to update the counter value after each 16 byte AES operation. The
counter buffer is updated appropriately to allow for incremental operations.
Please note the following IMPORTANT points about the AES mode subroutines:
1. All modes are reset when a new AES key is set.
2. Incremental calls to the different modes cannot
be mixed. If a change of mode is needed a new
key must be set or a reset must be issued (see
below).
3. For modes with IVs, the IV value is an inpu AND
an ouput since it is updated after each call to
the value needed for any subsequent incremental
call(s). If the mode is reset, the IV hence has
to be set (or reset) as well.
4. ECB operations must be multiples of 16 bytes
but do not need to be reset for new operations.
5. CBC operations must also be multiples of 16
bytes and are reset for a new operation by
setting the IV.
6. CFB, OFB and CTR mode must be reset by setting
a new IV value AND by calling:
aes_mode_reset(aes_encrypt_ctx cx[1])
For CTR mode the cbuf value also has to be reset.
7. CFB, OFB and CTR modes only use AES encryption
operations and contexts and do not need AES
decrytpion operations.
8. AES keys remain valid across resets and changes
of mode (but encryption and decryption keys must
both be set if they are needed).

; Issue 20/12/2007
;
; I am grateful to Dag Arne Osvik for many discussions of the techniques that
; can be used to optimise AES assembler code on AMD64/EM64T architectures.
; Some of the techniques used in this implementation are the result of
; suggestions made by him for which I am most grateful.
; An AES implementation for AMD64 processors using the YASM assembler. This
; implemetation provides only encryption, decryption and hence requires key
; scheduling support in C. It uses 8k bytes of tables but its encryption and
; decryption performance is very close to that obtained using large tables.
; It can use either Windows or Gnu/Linux calling conventions, which are as
; follows:
; windows gnu/linux
;
; in_blk rcx rdi
; out_blk rdx rsi
; context (cx) r8 rdx
;
; preserved rsi - + rbx, rbp, rsp, r12, r13, r14 & r15
; registers rdi - on both
;
; destroyed - rsi + rax, rcx, rdx, r8, r9, r10 & r11
; registers - rdi on both
;
; The default convention is that for windows, the gnu/linux convention being
; used if __GNUC__ is defined.
;
; Define _SEH_ to include support for Win64 structured exception handling
; (this requires YASM version 0.6 or later).
;
; This code provides the standard AES block size (128 bits, 16 bytes) and the
; three standard AES key sizes (128, 192 and 256 bits). It has the same call
; interface as my C implementation. It uses the Microsoft C AMD64 calling
; conventions in which the three parameters are placed in rcx, rdx and r8
; respectively. The rbx, rsi, rdi, rbp and r12..r15 registers are preserved.
;
; AES_RETURN aes_encrypt(const unsigned char in_blk[],
; unsigned char out_blk[], const aes_encrypt_ctx cx[1]);
;
; AES_RETURN aes_decrypt(const unsigned char in_blk[],
; unsigned char out_blk[], const aes_decrypt_ctx cx[1]);
;
; AES_RETURN aes_encrypt_key<NNN>(const unsigned char key[],
; const aes_encrypt_ctx cx[1]);
;
; AES_RETURN aes_decrypt_key<NNN>(const unsigned char key[],
; const aes_decrypt_ctx cx[1]);
;

;
; AES_RETURN aes_decrypt_key(const unsigned char key[],
; unsigned int len, const aes_decrypt_ctx cx[1]);
;
; where <NNN> is 128, 102 or 256. In the last two calls the length can be in
; either bits or bytes.
;
; Comment in/out the following lines to obtain the desired subroutines. These
; selections MUST match those in the C header file aes.h
%define AES_128 ; define if AES with 128 bit keys is needed
%define AES_192 ; define if AES with 192 bit keys is needed
%define AES_256 ; define if AES with 256 bit keys is needed
%define AES_VAR ; define if a variable key size is needed
%define ENCRYPTION ; define if encryption is needed
%define DECRYPTION ; define if decryption is needed
%define AES_REV_DKS ; define if key decryption schedule is reversed
%define LAST_ROUND_TABLES ; define for the faster version using extra tables
; The encryption key schedule has the following in memory layout where N is the
; number of rounds (10, 12 or 14):
;
; lo: | input key (round 0) | ; each round is four 32-bit words
; | encryption round 1 |
; | encryption round 2 |
; ....
; | encryption round N-1 |
; hi: | encryption round N |
;
; The decryption key schedule is normally set up so that it has the same
; layout as above by actually reversing the order of the encryption key
; schedule in memory (this happens when AES_REV_DKS is set):
;
; lo: | decryption round 0 | = | encryption round N |
; | decryption round 1 | = INV_MIX_COL[ | encryption round N-1 | ]
; | decryption round 2 | = INV_MIX_COL[ | encryption round N-2 | ]
; .... ....
; | decryption round N-1 | = INV_MIX_COL[ | encryption round 1 | ]
; hi: | decryption round N | = | input key (round 0) |
;
; with rounds except the first and last modified using inv_mix_column()
; But if AES_REV_DKS is NOT set the order of keys is left as it is for
; encryption so that it has to be accessed in reverse when used for
; decryption (although the inverse mix column modifications are done)
;
; lo: | decryption round 0 | = | input key (round 0) |
; | decryption round 1 | = INV_MIX_COL[ | encryption round 1 | ]
; | decryption round 2 | = INV_MIX_COL[ | encryption round 2 | ]
; .... ....
; | decryption round N-1 | = INV_MIX_COL[ | encryption round N-1 | ]
; hi: | decryption round N | = | encryption round N |
;
; This layout is faster when the assembler key scheduling provided here
; is used.
;
; The DLL interface must use the _stdcall convention in which the number
; of bytes of parameter space is added after an @ to the sutine's name.
; We must also remove our parameters from the stack before return (see
; the do_exit macro). Define DLL_EXPORT for the Dynamic Link Library version.

These subroutines implement multiple block AES modes for ECB, CBC, CFB,
OFB and CTR encryption, The code provides support for the VIA Advanced
Cryptography Engine (ACE).
NOTE: In the following subroutines, the AES contexts (ctx) must be
16 byte aligned if VIA ACE is being used

; Issue 13/08/2008
;
; This code requires ASM_X86_V1C to be set in aesopt.h. It requires the C files
; aeskey.c and aestab.c for support.
; An AES implementation for x86 processors using the YASM (or NASM) assembler.
; This is an assembler implementation that covers encryption and decryption
; only and is intended as a replacement of the C file aescrypt.c. It hence
; requires the file aeskey.c for keying and aestab.c for the AES tables. It
; employs full tables rather than compressed tables.
; This code provides the standard AES block size (128 bits, 16 bytes) and the
; three standard AES key sizes (128, 192 and 256 bits). It has the same call
; interface as my C implementation. The ebx, esi, edi and ebp registers are
; preserved across calls but eax, ecx and edx and the artihmetic status flags
; are not. It is also important that the defines below match those used in the
; C code. This code uses the VC++ register saving conentions; if it is used
; with another compiler, conventions for using and saving registers may need to
; be checked (and calling conventions). The YASM command line for the VC++
; custom build step is:
;
; yasm -Xvc -f win32 -o "$(TargetDir)\$(InputName).obj" "$(InputPath)"
;
; The calling intefaces are:
;
; AES_RETURN aes_encrypt(const unsigned char in_blk[],
; unsigned char out_blk[], const aes_encrypt_ctx cx[1]);
;
; AES_RETURN aes_decrypt(const unsigned char in_blk[],
; unsigned char out_blk[], const aes_decrypt_ctx cx[1]);
;
; AES_RETURN aes_encrypt_key<NNN>(const unsigned char key[],
; const aes_encrypt_ctx cx[1]);
;
; AES_RETURN aes_decrypt_key<NNN>(const unsigned char key[],
; const aes_decrypt_ctx cx[1]);
;
; AES_RETURN aes_encrypt_key(const unsigned char key[],
; unsigned int len, const aes_decrypt_ctx cx[1]);
;
; AES_RETURN aes_decrypt_key(const unsigned char key[],
; unsigned int len, const aes_decrypt_ctx cx[1]);
;
; where <NNN> is 128, 102 or 256. In the last two calls the length can be in
; either bits or bytes.
;
; Comment in/out the following lines to obtain the desired subroutines. These
; selections MUST match those in the C header file aes.h
%define AES_128 ; define if AES with 128 bit keys is needed

; The encryption key schedule has the following in memory layout where N is the
; number of rounds (10, 12 or 14):
;
; lo: | input key (round 0) | ; each round is four 32-bit words
; | encryption round 1 |
; | encryption round 2 |
; ....
; | encryption round N-1 |
; hi: | encryption round N |
;
; The decryption key schedule is normally set up so that it has the same
; layout as above by actually reversing the order of the encryption key
; schedule in memory (this happens when AES_REV_DKS is set):
;
; lo: | decryption round 0 | = | encryption round N |
; | decryption round 1 | = INV_MIX_COL[ | encryption round N-1 | ]
; | decryption round 2 | = INV_MIX_COL[ | encryption round N-2 | ]
; .... ....
; | decryption round N-1 | = INV_MIX_COL[ | encryption round 1 | ]
; hi: | decryption round N | = | input key (round 0) |
;
; with rounds except the first and last modified using inv_mix_column()
; But if AES_REV_DKS is NOT set the order of keys is left as it is for
; encryption so that it has to be accessed in reverse when used for
; decryption (although the inverse mix column modifications are done)
;

Issue Date: 20/12/2007
This file contains the compilation options for AES (Rijndael) and code
that is common across encryption, key scheduling and table generation.
OPERATION
These source code files implement the AES algorithm Rijndael designed by
Joan Daemen and Vincent Rijmen. This version is designed for the standard
block size of 16 bytes and for key sizes of 128, 192 and 256 bits (16, 24
and 32 bytes).
This version is designed for flexibility and speed using operations on
32-bit words rather than operations on bytes. It can be compiled with
either big or little endian internal byte order but is faster when the
native byte order for the processor is used.
THE CIPHER INTERFACE
The cipher interface is implemented as an array of bytes in which lower
AES bit sequence indexes map to higher numeric significance within bytes.
uint_8t (an unsigned 8-bit type)
uint_32t (an unsigned 32-bit type)
struct aes_encrypt_ctx (structure for the cipher encryption context)
struct aes_decrypt_ctx (structure for the cipher decryption context)
AES_RETURN the function return type
C subroutine calls:
AES_RETURN aes_encrypt_key128(const unsigned char *key, aes_encrypt_ctx cx[1]);
AES_RETURN aes_encrypt_key192(const unsigned char *key, aes_encrypt_ctx cx[1]);
AES_RETURN aes_encrypt_key256(const unsigned char *key, aes_encrypt_ctx cx[1]);
AES_RETURN aes_encrypt(const unsigned char *in, unsigned char *out,
const aes_encrypt_ctx cx[1]);
AES_RETURN aes_decrypt_key128(const unsigned char *key, aes_decrypt_ctx cx[1]);
AES_RETURN aes_decrypt_key192(const unsigned char *key, aes_decrypt_ctx cx[1]);
AES_RETURN aes_decrypt_key256(const unsigned char *key, aes_decrypt_ctx cx[1]);
AES_RETURN aes_decrypt(const unsigned char *in, unsigned char *out,
const aes_decrypt_ctx cx[1]);
IMPORTANT NOTE: If you are using this C interface with dynamic tables make sure that
you call aes_init() before AES is used so that the tables are initialised.

/* 1. BYTE ORDER WITHIN 32 BIT WORDS
The fundamental data processing units in Rijndael are 8-bit bytes. The
input, output and key input are all enumerated arrays of bytes in which
bytes are numbered starting at zero and increasing to one less than the
number of bytes in the array in question. This enumeration is only used
for naming bytes and does not imply any adjacency or order relationship
from one byte to another. When these inputs and outputs are considered
as bit sequences, bits 8*n to 8*n+7 of the bit sequence are mapped to
byte[n] with bit 8n+i in the sequence mapped to bit 7-i within the byte.
In this implementation bits are numbered from 0 to 7 starting at the
numerically least significant end of each byte (bit n represents 2^n).
However, Rijndael can be implemented more efficiently using 32-bit
words by packing bytes into words so that bytes 4*n to 4*n+3 are placed
into word[n]. While in principle these bytes can be assembled into words
in any positions, this implementation only supports the two formats in
which bytes in adjacent positions within words also have adjacent byte
numbers. This order is called big-endian if the lowest numbered bytes
in words have the highest numeric significance and little-endian if the
opposite applies.
This code can work in either order irrespective of the order used by the
machine on which it runs. Normally the internal byte order will be set
to the order of the processor on which the code is to be run but this
define can be used to reverse this in special situations
WARNING: Assembler code versions rely on PLATFORM_BYTE_ORDER being set.
This define will hence be redefined later (in section 4) if necessary

/* 4. FAST INPUT/OUTPUT OPERATIONS.
On some machines it is possible to improve speed by transferring the
bytes in the input and output arrays to and from the internal 32-bit
variables by addressing these arrays as if they are arrays of 32-bit
words. On some machines this will always be possible but there may
be a large performance penalty if the byte arrays are not aligned on
the normal word boundaries. On other machines this technique will
lead to memory access errors when such 32-bit word accesses are not
properly aligned. The option SAFE_IO avoids such problems but will
often be slower on those machines that support misaligned access
(especially so if care is taken to align the input and output byte
arrays on 32-bit word boundaries). If SAFE_IO is not defined it is
assumed that access to byte arrays as if they are arrays of 32-bit
words will not cause problems when such accesses are misaligned.

how much speed is required. The encryption and decryption round functions

Issue Date: 20/12/2007
This file contains the code for declaring the tables needed to implement
AES. The file aesopt.h is assumed to be included before this header file.
If there are no global variables, the definitions here can be used to put
the AES tables in a structure so that a pointer can then be added to the
AES context to pass them to the AES routines that need them. If this
facility is used, the calling program has to ensure that this pointer is
managed appropriately. In particular, the value of the t_dec(in,it) item
in the table structure must be set to zero in order to ensure that the
tables are initialised. In practice the three code sequences in aeskey.c
that control the calls to aes_init() and the aes_init() routine itself will
have to be changed for a specific implementation. If global variables are
available it will generally be preferable to use them with the precomputed
FIXED_TABLES option that uses static global tables.
The following defines can be used to control the way the tables
are defined, initialised and used in embedded environments that
require special features for these purposes
the 't_dec' construction is used to declare fixed table arrays
the 't_set' construction is used to set fixed table values
the 't_use' construction is used to access fixed table values
256 byte tables:
t_xxx(s,box) => forward S box
t_xxx(i,box) => inverse S box
256 32-bit word OR 4 x 256 32-bit word tables:
t_xxx(f,n) => forward normal round
t_xxx(f,l) => forward last round
t_xxx(i,n) => inverse normal round
t_xxx(i,l) => inverse last round
t_xxx(l,s) => key schedule table
t_xxx(i,m) => key schedule table
Other variables and tables:
t_xxx(r,c) => the rcon table

// An example of the use of AES (Rijndael) for file encryption. This code
// implements AES in CBC mode with ciphertext stealing when the file length
// is greater than one block (16 bytes). This code is an example of how to
// use AES and is not intended for real use since it does not provide any
// file integrity checking.
//
// The Command line is:
//
// aesxam input_file_name output_file_name [D|E] hexadecimalkey
//
// where E gives encryption and D decryption of the input file into the
// output file using the given hexadecimal key string. The later is a
// hexadecimal sequence of 32, 48 or 64 digits. Examples to encrypt or
// decrypt aes.c into aes.enc are:
//
// aesxam file.c file.enc E 0123456789abcdeffedcba9876543210
//
// aesxam file.enc file2.c D 0123456789abcdeffedcba9876543210
//
// which should return a file 'file2.c' identical to 'file.c'
//
// CIPHERTEXT STEALING
//
// Ciphertext stealing modifies the encryption of the last two CBC
// blocks. It can be applied invariably to the last two plaintext
// blocks or only applied when the last block is a partial one. In
// this code it is only applied if there is a partial block. For
// a plaintext consisting of N blocks, with the last block possibly
// a partial one, ciphertext stealing works as shown below (note the
// reversal of the last two ciphertext blocks). During decryption
// the part of the C:N-1 block that is not transmitted (X) can be
// obtained from the decryption of the penultimate ciphertext block
// since the bytes in X are xored with the zero padding appended to
// the last plaintext block.
//
// This is a picture of the processing of the last
// plaintext blocks during encryption:
//
// +---------+ +---------+ +---------+ +-------+-+

Issue Date: 20/12/2007
The unsigned integer types defined here are of the form uint_<nn>t where
<nn> is the length of the type; for example, the unsigned 32-bit type is
'uint_32t'. These are NOT the same as the 'C99 integer types' that are
defined in the inttypes.h and stdint.h headers since attempts to use these
types have shown that support for them is still highly variable. However,
since the latter are of the form uint<nn>_t, a regular expression search
and replace (in VC++ search on 'uint_{:z}t' and replace with 'uint\1_t')
can be used to convert the types used here to the C99 standard types.

Support for the VIA Nehemiah Advanced Cryptography Engine (ACE)
---------------------------------------------------------------
A. Introduction
The AES code now supports the VIA ACE engine. The engine is invoked by the
multiple block AES modes calls in aes_modes.c and not by the basic AES code.
The define USE_VIA_ACE_IF_PRESENT is defined if VIA ACE detection and use is
required with fallback to the normal AES code if it is not present.
The define ASSUME_VIA_ACE_PRESENT is used when it is known that the VIA ACE
engine will always be present. Note, however, that this code will not work
correctly if the VIA ACE engine is either not present or turned off.
To enable ACE support the appropriate defines in section 2 of the options in
aesopt.h must be set. If ACE support is required then key scheduling must
use the C code so only the generic C code in Win32 mode, ASM_X86_V1C and
ASM_X86_V2C assembler code can be used (i.e ASM_X86_V2 and ASM_AMD64_C do
NOT support VIA ACE).
B. Using ACE
ACE is used in the code that implements the subroutines used for the multiple
block AES modes defined in aes_modes.h:
// used to reset modes to their start point without entering a new key
AES_RETURN aes_mode_reset(aes_encrypt_ctx cx[1]);
AES_RETURN aes_ecb_encrypt(const unsigned char *ibuf, unsigned char *obuf,
int len, const aes_encrypt_ctx cx[1]);
AES_RETURN aes_ecb_decrypt(const unsigned char *ibuf, unsigned char *obuf,
int len, const aes_decrypt_ctx cx[1]);
AES_RETURN aes_cbc_encrypt(const unsigned char *ibuf, unsigned char *obuf,
int len, unsigned char *iv, const aes_encrypt_ctx cx[1]);
AES_RETURN aes_cbc_decrypt(const unsigned char *ibuf, unsigned char *obuf,
int len, unsigned char *iv, const aes_decrypt_ctx cx[1]);
AES_RETURN aes_cfb_encrypt(const unsigned char *ibuf, unsigned char *obuf,
int len, unsigned char *iv, aes_encrypt_ctx cx[1]);
AES_RETURN aes_cfb_decrypt(const unsigned char *ibuf, unsigned char *obuf,
int len, unsigned char *iv, aes_encrypt_ctx cx[1]);
#define aes_ofb_encrypt aes_ofb_crypt
#define aes_ofb_decrypt aes_ofb_crypt
AES_RETURN aes_ofb_crypt(const unsigned char *ibuf, unsigned char *obuf,
int len, unsigned char *iv, aes_encrypt_ctx cx[1]);
typedef void cbuf_inc(unsigned char *cbuf);
#define aes_ctr_encrypt aes_ctr_crypt
#define aes_ctr_decrypt aes_ctr_crypt
AES_RETURN aes_ctr_crypt(const unsigned char *ibuf, unsigned char *obuf,
int len, unsigned char *cbuf, cbuf_inc ctr_inc, aes_encrypt_ctx cx[1]);
Note that the single block AES calls defined in aes.h:
AES_RETURN aes_encrypt(const unsigned char *in, unsigned char *out,
const aes_encrypt_ctx cx[1]);
AES_RETURN aes_decrypt(const unsigned char *in, unsigned char *out,
const aes_decrypt_ctx cx[1]);
do NOT provide ACE support and should not be used if the ACE engine is
available and ACE support is required.
C. Constraints and Optimisation
There are several constraints that have to be observed when ACE is used if
the best performance is to be achieved:
1. As usual the appropriate key set up subroutine must be called before any
of the above subroutines are used.
2. The AES contexts - aes_encryption_ctx and aes_decryption_ctx - used with
these subroutines MUST be 16 byte aligned. Failure to align AES contexts
will often cause memory alignment exceptions.
3. The buffers used for inputs, outputs and IVs do not need to be 16 byte
aligned but the speed that is achieved will be much higher if this can be
arranged. In a flat address space (as now typical in 32-bit systems) this
means that: (a) that the lower nibble of all buffer addresses must be
zero, and (b) the compiler used must arrange to load the data and stack
segments on 16 byte address boundaries. The Microsoft VC++ compiler can
align all variables in this way (see the example macros for doing this in
aes_via_ace.txt). However it seems that the GCC compiler will only do this
for static global variables but not for variables placed on the stack, that
is local variables.
4. The data length in bytes (len) in calls to the ECB and CBC subroutines
must be a multiple of the 16 byte block length. An error return will
occur if this is not so.
5. The data length in all calls to the CFB, OFB and CTR subroutines must also
be a multiple of 16 bytes if the VIA ACE engine is to be used. Otherwise
these lengths can be of any value but the subroutines will only proceed at
full speed for lengths that are multiples of 16 bytes. The CFB, OFB and
CTR subroutines are incremental, with subsequent calls continuing from
where previous calls finished. The subroutine aes_mode_reset() can be used
to restart a mode without a key change but is not needed after a new key is
entered. Such a reset is not needed when the data lengths in all individual
calls to the AES mode subroutines are multiples of 16 bytes.
6. Note that the AES context contains mode details so only one type of mode
can be run from a context at any one time. A reset is necessary if a new
mode is used without a new context or a new key.
D. Expected Speeds
The speeds that have been obtained using a 1.2 GHz VIA C3 processor with
this code are given below (note that since CTR mode is not available in
the VIA hardware it is not present in the aligned timing figures):

Additions allow you to add arbitrary C# to the generated classes
before they are compiled. This can be helpful for providing convenience
methods or adding pure C# classes.
== Adding Methods to Generated Classes ==
Let's say the library being bound has a Rectangle class with a constructor
that takes an x and y position, and a width and length size. It will look like
this:
public partial class Rectangle
{
public Rectangle (int x, int y, int width, int height)
{
// JNI bindings
}
}
Imagine we want to add a constructor to this class that takes a Point and
Size structure instead of 4 ints. We can add a new file called Rectangle.cs
with a partial class containing our new method:
public partial class Rectangle
{
public Rectangle (Point location, Size size) :
this (location.X, location.Y, size.Width, size.Height)
{
}
}
At compile time, the additions class will be added to the generated class
and the final assembly will a Rectangle class with both constructors.
== Adding C# Classes ==
Another thing that can be done is adding fully C# managed classes to the
generated library. In the above example, let's assume that there isn't a
Point class available in Java or our library. The one we create doesn't need
to interact with Java, so we'll create it like a normal class in C#.
By adding a Point.cs file with this class, it will end up in the binding library:
public class Point
{
public int X { get; set; }
public int Y { get; set; }
}

This directory is for Android .jars.
There are 3 types of jars that are supported:
== Input Jar and Embedded Jar ==
This is the jar that bindings should be generated for.
For example, if you were binding the Google Maps library, this would
be Google's "maps.jar".
The difference between EmbeddedJar and InputJar is, EmbeddedJar is to be
embedded in the resulting dll as EmbeddedResource, while InputJar is not.
There are couple of reasons you wouldn't like to embed the target jar
in your dll (the ones that could be internally loaded by <uses-library>
feature e.g. maps.jar, or you cannot embed jars that are under some
proprietary license).
Set the build action for these jars in the properties page to "InputJar".
== Reference Jar and Embedded Reference Jar ==
These are jars that are referenced by the input jar. C# bindings will
not be created for these jars. These jars will be used to resolve
types used by the input jar.
NOTE: Do not add "android.jar" as a reference jar. It will be added automatically
based on the Target Framework selected.
Set the build action for these jars in the properties page to "ReferenceJar".
"EmbeddedJar" works like "ReferenceJar", but like "EmbeddedJar", it is
embedded in your dll. But at application build time, they are not included
in the final apk, like ReferenceJar files.
