What is an Encryption And Decryption

[wavic]

Hm! The simplest encryption for me is just to use a bitwise xor against some key.

>>> word = 'hello world'
>>> enc = "".join([chr(ord(char) ^ ord('a')) for char in word])
>>> enc
'\t\x04\r\r\x0eA\x16\x0e\x13\r\x05'
>>> dec = "".join([chr(ord(char) ^ ord('a')) for char in enc])
>>> dec
'hello world'
