decrypt a as3crypto encrypted text in PHP

Question

i tried to encrypt a text in as3crypto via the demo app.

now i am trying to decrypt the crypted text via php but it seems that the text is not properly decrypted. ha

Answer 1

This would work:

PHP code:

//notice that $key and $iv length must be 16 chars long! ex: 1234567890123456
function decrypt($data,$key,$iv)
{

    $decr= mcrypt_decrypt(MCRYPT_RIJNDAEL_128, $key, base64_decode($data), MCRYPT_MODE_CBC, $iv);    
    return $decr;   
}

And here is AS3 code

//notice that $key and $iv length must be 16 chars long! ex: 1234567890123456
private function encrypt(input:String,decrKey:String,decrIV:String):String
{
    var inputBA:ByteArray=Hex.toArray(Hex.fromString(input));        
    var key:ByteArray = Hex.toArray(Hex.fromString(decrKey));                
    var pad:IPad = new NullPad();
    var aes:ICipher = Crypto.getCipher("aes-cbc", key, pad);
    var ivmode:IVMode = aes as IVMode;
    ivmode.IV = Hex.toArray(Hex.fromString(decrIV));            
    aes.encrypt(inputBA);  

    return Base64.encodeByteArray( inputBA);
}
