How to use implement AES_DECRYPT() of MySQL by Python

问题

I am trying to write a python code which has same functionarities of AES_ENCRYPT and AES_DECRYPT of MySQL. https://dev.mysql.com/doc/refman/5.6/ja/encryption-functions.html

I want to encrypt and decrypt data between MySQL and Python.

For example, I want to decrypt data by python, which is encrypted by AES_ENCRYPT of MySQL.

And I want to decrypt data by AES_DECRYPT of MySQL, which is encrypted by Python vice versa.

I found a example of AES_ENCRYPT in Python. https://www.maykinmedia.nl/blog/2012/nov/15/mysql-aes_encrypt-python/

Does anyone know how to implement the decryption part?

回答1:

I did it finally.

def mysql_aes_decrypt(val, key):

    def mysql_aes_key(key):
        final_key = bytearray(16)
        for i, c in enumerate(key):
            final_key[i % 16] ^= ord(key[i])
        return bytes(final_key)

    k = mysql_aes_key(key)

    cipher = AES.new(k, AES.MODE_ECB)

    return cipher.decrypt(val).decode()
