I'm looking for AES256 CBC decryption client side,
in nodeJS I use this function to encrypt:
exports.encrypt = function(txt, cryptkey){
var cipher = crypto.createCipher('aes-256-cbc',cryptkey);
var crypted = cipher.update(txt,'utf8','hex');
crypted += cipher.final('hex');
console.log(crypted);
return crypted;
};
but I can't seem to work with it in any client side library (JSAES.js, SJCL.js, pidcrypt)
my guess is it has something to do with the base64/hex encoding decoding, any pointers?

Please have a look at the CryptoJS project:
Here is an example of AES256 CBC encryption / decryption:
Include:
<script src="http://crypto-js.googlecode.com/svn/tags/3.1.2/build/rollups/aes.js"></script>
<script src="http://crypto-js.googlecode.com/svn/tags/3.1.2/build/components/mode-cfb-min.js"></script>
JS:
var passPhrase = "Secret Phassphrase";
var encrypted = CryptoJS.AES.encrypt("Message", passPhrase, { mode: CryptoJS.mode.CFB });
var decrypted = CryptoJS.AES.decrypt(encrypted, passPhrase, { mode: CryptoJS.mode.CFB });
console.log('encrypted', encrypted);
console.log('decrypted', decrypted.toString(CryptoJS.enc.Utf8));
