How to implement XOR encryption?

Question

Python

Hello.
I'm trying to write a small program for XOR encryption.
There were problems with the implementation, due to lack of knowledge.
It is necessary to implement the input of a message and a key from the keyboard.
Encrypt and output the cipher.
Decrypt and output.
Now I'm trying to translate each letter separately in the message

for letter in message:
        print bin(ord(letter))[2:]

And I don't know what to do next.
I think that you still need to check for the number of characters:

while список.__len__() < 8:
    список.insert(0, '0')

What do you advise?
Or maybe there are already ready-made solutions that you can figure out.

Answer 1

This type of encryption is in pycrypto

from Crypto.Cipher import XOR
key = '123'
cipher = XOR.new(key)
text = 'plaintext'
cipher.encrypt(text)

Answer 2

in what language?
