Can IT Tutorial Decrypting in Python

Decrypting the Data in Python is pretty straightforward here is an example of decrypting encrypted data.

your_key = "ABCDEFGHIJKLMNOP"

def decrypt_my_message(msg):
    iv = "1234567812345678"
    key = your_key
    if len(key) not in (16, 24, 32):
        raise ValueError("Key must be 16, 24, or 32 bytes")
    if (len(msg) % 16) != 0:
        raise ValueError("Message must be a multiple of 16 bytes")
    if len(iv) != 16:
        raise ValueError("IV must be 16 bytes")
    cipher = AES.new(key, AES.MODE_CBC, iv)
    plaintext = cipher.decrypt(msg)
    return plaintext

We check if our key is of a proper length. Then we check if the message is of 16 bytes, and finally our iv should be 16 bytes.

then call decrypt and return our decrypted message. Obviously the message would need to be encrypted to be passed to the decrypt_my_message function

Anyway that is it hope you enjoyed my simple tutorial
