Decrypting strings in Python that were encrypted with MCRYPT_RIJNDAEL_256 in PHP

Question

I have a function in PHP that encrypts text as follows:

function encrypt($text)
{
    $Key = \"MyKey\";

    return trim(base64_encode(mcrypt_encrypt(MCRYPT_         


        

Answer 1

If you're willing to use MCRYPT_RIJNDAEL_128 rather than 256 on the PHP side, this is as simple as:

from Crypto.Cipher import AES
import base64
key="MyKey"

def decrypt(text)
    cipher=AES.new(key)
    return cipher.decrypt(base64.b64decode(text))
