|
|
functions.

<h3>LICENSE</h3>
|

The 'jsrsasign'(RSA-Sign JavaScript Library) is licensed under the terms of the MIT license
|

reproduced below.

<h3>How to sign</h3>
|
||
|
|
<pre><blockquote style="background:lightgray">
|
||
|
|
var rsa = new RSAKey();
|
||
|
|
rsa.readPrivateKeyFromPEMString(_PEM_PRIVATE_KEY_STRING_);
|
||
|
|
var hSig = rsa.signString("aaa", "sha1"); // sign a string "aaa" with key
|
||
|
|
</blockquote></pre>
|
||
|
|
|
||
|
|
<h3>How to verify signature</h3>
|
||
|
|
<pre><blockquote style="background:lightgray">
|
||
|
|
vr x509 = new X509();
|
||
|
|
x509.readCertPEM(_PEM_X509CERT_STRING_);
|
||
|
|
var result = x509.subjectPublicKeyRSA.verifyString("aaa", _HEX_SIGNATURE_);
|
||
|
|
</blockquote></pre>
|
||
|
|
|
||
|
|
<h3>How to add supported signature algorithms</h3>
|
||
|
|
The script "rsa-sign.js" currently supports
|
||
|
|
SHA1withRSA,
|
||
|
|
SHA256withRSA,
|
||
|
|
SHA512withRSA,
|
||
|
|
MD5withRSA and
|
||
|
|
RIPEMD160withRSA
|
||
|
|
signature algorithms. However you can extend other signature algorithms
|
||
|
|
such like MD2withRSA or SHA384withRSA by just specifying two variables in it.
|
||
|
|
<pre><blockquote style="background:lightgray">
|
||
|
|
_RSASIGN_DIHEAD['md2'] = "30..."; // Hexadecimal DigestInfo prefix for MD5
|
||
|
|
_RSASIGN_HASHHEXFUNC['md2'] = md2hex; // function which returns value in hex.
|
||
|
|
</blockquote></pre>
|
||
|
|
|
||
