proxy: Support HTTPS proxy and SOCKS+HTTP(s)

Browse Source 
* HTTPS proxies:

An HTTPS proxy receives all transactions over an SSL/TLS connection.
Once a secure connection with the proxy is established, the user agent
uses the proxy as usual, including sending CONNECT requests to instruct
the proxy to establish a [usually secure] TCP tunnel with an origin
server. HTTPS proxies protect nearly all aspects of user-proxy
communications as opposed to HTTP proxies that receive all requests
(including CONNECT requests) in vulnerable clear text.

With HTTPS proxies, it is possible to have two concurrent _nested_
SSL/TLS sessions: the "outer" one between the user agent and the proxy
and the "inner" one between the user agent and the origin server
(through the proxy). This change adds supports for such nested sessions
as well.

A secure connection with a proxy requires its own set of the usual SSL
options (their actual descriptions differ and need polishing, see TODO):

  --proxy-cacert FILE        CA certificate to verify peer against
  --proxy-capath DIR         CA directory to verify peer against
  --proxy-cert CERT[:PASSWD] Client certificate file and password
  --proxy-cert-type TYPE     Certificate file type (DER/PEM/ENG)
  --proxy-ciphers LIST       SSL ciphers to use
  --proxy-crlfile FILE       Get a CRL list in PEM format from the file
  --proxy-insecure           Allow connections to proxies with bad certs
  --proxy-key KEY            Private key file name
  --proxy-key-type TYPE      Private key file type (DER/PEM/ENG)
  --proxy-pass PASS          Pass phrase for the private key
  --proxy-ssl-allow-beast    Allow security flaw to improve interop
  --proxy-sslv2              Use SSLv2
  --proxy-sslv3              Use SSLv3
  --proxy-tlsv1              Use TLSv1
  --proxy-tlsuser USER       TLS username
  --proxy-tlspassword STRING TLS password
  --proxy-tlsauthtype STRING TLS authentication type (default SRP)

All --proxy-foo options are independent from their --foo counterparts,
except --proxy-crlfile which defaults to --crlfile and --proxy-capath
which defaults to --capath.

Curl now also supports %{proxy_ssl_verify_result} --write-out variable,
similar to the existing %{ssl_verify_result} variable.

Supported backends: OpenSSL, GnuTLS, and NSS.

* A SOCKS proxy + HTTP/HTTPS proxy combination:

If both --socks* and --proxy options are given, Curl first connects to
the SOCKS proxy and then connects (through SOCKS) to the HTTP or HTTPS
proxy.

TODO: Update documentation for the new APIs and --proxy-* options.

CURLOPT_PROXY_CAINFO \- path to proxy Certificate Authority (CA) bundle
.SH SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_CAINFO, char *path);
.SH DESCRIPTION
TODO: Make this text specific to HTTPS proxy. (Added in 7.XXX)
Pass a char * to a zero terminated string naming a file holding one or more
certificates to verify the peer with.
If \fICURLOPT_SSL_VERIFYPEER(3)\fP is zero and you avoid verifying the
server's certificate, \fICURLOPT_CAINFO(3)\fP need not even indicate an
accessible file.
This option is by default set to the system path where libcurl's cacert bundle
is assumed to be stored, as established at build time.
If curl is built against the NSS SSL library, the NSS PEM PKCS#11 module
(libnsspem.so) needs to be available for this option to work properly.
(iOS and macOS only) If curl is built against Secure Transport, then this
option is supported for backward compatibility with other SSL engines, but it
should not be set. If the option is not set, then curl will use the
certificates in the system and user Keychain to verify the peer, which is the
preferred method of verifying the peer's certificate chain.
.SH DEFAULT
Built-in system specific
.SH PROTOCOLS
All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.
.SH EXAMPLE
TODO
.SH AVAILABILITY
For SSL engines that don't support certificate files the CURLOPT_PROXY_CAINFO option
is ignored. Refer to https://curl.haxx.se/docs/ssl-compared.html

CURLOPT_PROXY_CRLFILE \- specify a proxy Certificate Revocation List file

#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_CRLFILE, char *file);
.SH DESCRIPTION
TODO: Make this text specific to HTTPS proxy. (Added in 7.XXX)
Pass a char * to a zero terminated string naming a \fIfile\fP with the
concatenation of CRL (in PEM format) to use in the certificate validation that
occurs during the SSL exchange.
When curl is built to use NSS or GnuTLS, there is no way to influence the use
of CRL passed to help in the verification process. When libcurl is built with
OpenSSL support, X509_V_FLAG_CRL_CHECK and X509_V_FLAG_CRL_CHECK_ALL are both
set, requiring CRL check against all the elements of the certificate chain if
a CRL file is passed.
This option makes sense only when used in combination with the
\fICURLOPT_SSL_VERIFYPEER(3)\fP option.
A specific error code (\fICURLE_SSL_CRL_BADFILE\fP) is defined with the
option. It is returned when the SSL exchange fails because the CRL file cannot
be loaded. A failure in certificate verification due to a revocation
information found in the CRL does not trigger this specific error.

.SH DESCRIPTION
TODO: Make this text specific to HTTPS proxy. (Added in 7.XXX)
Pass a pointer to a zero terminated string as parameter. The string should be
the file name of your client certificate. The default format is "P12" on
Secure Transport and "PEM" on other engines, and can be changed with
\fICURLOPT_SSLCERTTYPE(3)\fP.
With NSS or Secure Transport, this can also be the nickname of the certificate
you wish to authenticate with as it is named in the security database. If you
want to use a file from the current directory, please precede it with "./"
prefix, in order to avoid confusion with a nickname.
When using a client certificate, you most likely also need to provide a
private key with \fICURLOPT_SSLKEY(3)\fP.

TODO: Make this text specific to HTTPS proxy. (Added in 7.XXX)
Pass a char *, pointing to a zero terminated string holding the list of
ciphers to use for the SSL connection. The list must be syntactically correct,
it consists of one or more cipher strings separated by colons. Commas or
spaces are also acceptable separators but colons are normally used, \&!, \&-
and \&+ can be used as operators.
For OpenSSL and GnuTLS valid examples of cipher lists include 'RC4-SHA',
\'SHA1+DES\', 'TLSv1' and 'DEFAULT'. The default list is normally set when you
compile OpenSSL.
You'll find more details about cipher lists on this URL:
https://www.openssl.org/docs/apps/ciphers.html
For NSS, valid examples of cipher lists include 'rsa_rc4_128_md5',
\'rsa_aes_128_sha\', etc. With NSS you don't add/remove ciphers. If one uses
this option then all known ciphers are disabled and only those passed in are
enabled.

.SH DESCRIPTION
TODO: Make this text specific to HTTPS proxy. (Added in 7.XXX)
Pass a long with a bitmask to tell libcurl about specific SSL behaviors.
\fICURLSSLOPT_ALLOW_BEAST\fP tells libcurl to not attempt to use any
workarounds for a security flaw in the SSL3 and TLS1.0 protocols. If this
option isn't used or this bit is set to 0, the SSL layer libcurl uses may use a
work-around for this flaw although it might cause interoperability problems
with some (older) SSL implementations. WARNING: avoiding this work-around
lessens the security, and by setting this option to 1 you ask for exactly that.
This option is only supported for DarwinSSL, NSS and OpenSSL.
Added in 7.44.0:
\fICURLSSLOPT_NO_REVOKE\fP tells libcurl to disable certificate revocation
checks for those SSL backends where such behavior is present. \fBCurrently this
option is only supported for WinSSL (the native Windows SSL library), with an
exception in the case of Windows' Untrusted Publishers blacklist which it seems
can't be bypassed.\fP This option may have broader support to accommodate other
SSL backends in the future.

.SH NAME
CURLOPT_PROXY_SSL_VERIFYHOST \- verify the proxy certificate's name against host
.SH SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_SSL_VERIFYHOST, long verify);
.SH DESCRIPTION
TODO: Make this text specific to HTTPS proxy. (Added in 7.XXX)
Pass a long as parameter specifying what to \fIverify\fP.
This option determines whether libcurl verifies that the server cert is for
the server it is known as.
When negotiating TLS and SSL connections, the server sends a certificate
indicating its identity.
When \fICURLOPT_SSL_VERIFYHOST(3)\fP is 2, that certificate must indicate that
the server is the server to which you meant to connect, or the connection
fails. Simply put, it means it has to have the same name in the certificate as
is in the URL you operate against.
Curl considers the server the intended one when the Common Name field or a
Subject Alternate Name field in the certificate matches the host name in the
URL to which you told Curl to connect.
When the \fIverify\fP value is 1, \fIcurl_easy_setopt\fP will return an error
and the option value will not be changed. It was previously (in 7.28.0 and
earlier) a debug option of some sorts, but it is no longer supported due to
frequently leading to programmer mistakes. Future versions will stop returning
an error for 1 and just treat 1 and 2 the same.
When the \fIverify\fP value is 0, the connection succeeds regardless of the
names in the certificate. Use that ability with caution!
The default value for this option is 2.
This option controls checking the server's certificate's claimed identity.
The server could be lying. To control lying, see
\fICURLOPT_SSL_VERIFYPEER(3)\fP. If libcurl is built against NSS and
\fICURLOPT_SSL_VERIFYPEER(3)\fP is zero, \fICURLOPT_SSL_VERIFYHOST(3)\fP is
also set to zero and cannot be overridden.

.SH NAME
CURLOPT_PROXY_SSL_VERIFYPEER \- verify the proxy peer's SSL certificate
.SH SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_SSL_VERIFYPEER, long verify);
.SH DESCRIPTION
TODO: Make this text specific to HTTPS proxy. (Added in 7.XXX)
Pass a long as parameter to enable or disable.
This option determines whether curl verifies the authenticity of the peer's
certificate. A value of 1 means curl verifies; 0 (zero) means it doesn't.
When negotiating a TLS or SSL connection, the server sends a certificate
indicating its identity. Curl verifies whether the certificate is authentic,
i.e. that you can trust that the server is who the certificate says it is.
This trust is based on a chain of digital signatures, rooted in certification
authority (CA) certificates you supply. curl uses a default bundle of CA
certificates (the path for that is determined at build time) and you can
specify alternate certificates with the \fICURLOPT_CAINFO(3)\fP option or the
\fICURLOPT_CAPATH(3)\fP option.
When \fICURLOPT_SSL_VERIFYPEER(3)\fP is enabled, and the verification fails to
prove that the certificate is authentic, the connection fails. When the
option is zero, the peer certificate verification succeeds regardless.
Authenticating the certificate is not enough to be sure about the server. You
typically also want to ensure that the server is the server you mean to be
talking to. Use \fICURLOPT_SSL_VERIFYHOST(3)\fP for that. The check that the
host name in the certificate is valid for the host name you're connecting to
is done independently of the \fICURLOPT_SSL_VERIFYPEER(3)\fP option.
WARNING: disabling verification of the certificate allows bad guys to
man-in-the-middle the communication without you knowing it. Disabling
verification makes the communication insecure. Just having encryption on a
transfer is not enough as you cannot be sure that you are communicating with
the correct end-point.
.SH DEFAULT
By default, curl assumes a value of 1.

.SH SYNOPSIS
#include <curl/curl.h>

.SH DESCRIPTION
TODO: Make this text specific to HTTPS proxy. (Added in 7.XXX)
Pass a pointer to a zero terminated string as parameter. The string
should be the method of the TLS authentication. Supported method is "SRP".
.IP SRP
TLS-SRP authentication. Secure Remote Password authentication for TLS is
defined in RFC5054 and provides mutual authentication if both sides have a
shared secret. To use TLS-SRP, you must also set the
\fICURLOPT_TLSAUTH_USERNAME(3)\fP and \fICURLOPT_TLSAUTH_PASSWORD(3)\fP
options.
.SH DEFAULT

.SH AVAILABILITY
You need to build libcurl with GnuTLS or OpenSSL with TLS-SRP support for this
to work.
.SH RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.

.TH CURLOPT_SOCKS_PROXY 3 "16 Nov 2016" "libcurl 7.51.1" "curl_easy_setopt options"
.SH NAME
CURLOPT_SOCKS_PROXY \- set socks proxy to use
.SH SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SOCKS_PROXY, char *proxy);
.SH DESCRIPTION
TODO: Make this text specific to HTTPS proxy. (Added in 7.XXX)
Set the \fIproxy\fP to use for the upcoming request. The parameter should be a
char * to a zero terminated string holding the host name or dotted numerical
IP address. A numerical IPv6 address must be written within [brackets].
To specify port number in this string, append :[port] to the end of the host
name. The proxy's port number may optionally be specified with the separate
option \fICURLOPT_PROXYPORT(3)\fP. If not specified, libcurl will default to
using port 1080 for proxies.
The proxy string may be prefixed with [scheme]:// to specify which kind of
proxy is used. Use socks4://, socks4a://, socks5:// or socks5h:// (the last
one to enable socks5 and asking the proxy to do the resolving, also known as
\fICURLPROXY_SOCKS5_HOSTNAME\fP type) to request the specific SOCKS version to
be used. No scheme specified or http://, will be treated as HTTP proxies.
Without a scheme prefix, \fICURLOPT_PROXYTYPE(3)\fP can be used to specify
which kind of proxy the string identifies.
When you tell the library to use a HTTP proxy, libcurl will transparently
convert operations to HTTP even if you specify an FTP URL etc. This may have
an impact on what other features of the library you can use, such as
\fICURLOPT_QUOTE(3)\fP and similar FTP specifics that don't work unless you
tunnel through the HTTP proxy. Such tunneling is activated with
\fICURLOPT_HTTPPROXYTUNNEL(3)\fP.
libcurl respects the environment variables \fBhttp_proxy\fP, \fBftp_proxy\fP,
\fBall_proxy\fP etc, if any of those are set. The \fICURLOPT_PROXY(3)\fP
option does however override any possibly set environment variables.
Setting the proxy string to "" (an empty string) will explicitly disable the
use of a proxy, even if there is an environment variable set for it.
A proxy host string can also include protocol scheme (http://) and embedded
user + password.
.SH DEFAULT
Default is NULL, meaning no proxy is used.
When you set a host name to use, do not assume that there's any particular
single port number used widely for proxies. Specify it!
.SH PROTOCOLS
All except file://. Note that some protocols don't do very well over proxy.
.SH EXAMPLE
TODO
.SH AVAILABILITY
Since 7.14.1 the proxy environment variable names can include the protocol
scheme.
Since 7.21.7 the proxy string supports the socks protocols as "schemes".
Since 7.50.2, unsupported schemes in proxy strings cause libcurl to return
error.
.SH RETURN VALUE
Returns CURLE_OK if proxies are supported, CURLE_UNKNOWN_OPTION if not, or
CURLE_OUT_OF_MEMORY if there was insufficient heap space.
.SH "SEE ALSO"

CURLOPT_SOCKS_PROXYTYPE \- socks proxy protocol type
.SH SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SOCKS_PROXYTYPE, long type);
.SH DESCRIPTION
TODO: Make this text specific to HTTPS proxy. (Added in 7.XXX)
Pass a long with this option to set type of the proxy. Available options for
this are \fICURLPROXY_HTTP\fP, \fICURLPROXY_HTTP_1_0\fP
\fICURLPROXY_SOCKS4\fP, \fICURLPROXY_SOCKS5\fP, \fICURLPROXY_SOCKS4A\fP and
\fICURLPROXY_SOCKS5_HOSTNAME\fP. The HTTP type is default.
If you set \fICURLOPT_PROXYTYPE(3)\fP to \fICURLPROXY_HTTP_1_0\fP, it will
only affect how libcurl speaks to a proxy when CONNECT is used. The HTTP
version used for "regular" HTTP requests is instead controlled with
\fICURLOPT_HTTP_VERSION(3)\fP.
Often it is more convenient to specify the proxy type with the scheme part of
the \fICURLOPT_PROXY(3)\fP string.
