Day096 — AES encryption in Python

Here are the things I learned in a Python project involves encryption.

Convert string to bytes:

'abcde'.encode()

Best way to convert string to bytes in Python 3?

Convert bytes to string:

b"abcde".decode("utf-8")

Convert bytes to a string?

fix ValueError: Input strings must be a multiple of 16 in length:

AES: Input strings must be a multiple of 16 in length

pad and unpad (fill up string to a multiple of 16):

pad = lambda s: s + (BS - len(s) % BS) * chr(BS - len(s) % BS)
unpad = lambda s: s[0:-ord(s[-1])]
