One-Time-Pad Python

A hacky implementation of One-time Pad in Python

Download this project as a .zip file Download this project as a tar.gz file

One-Time-Pad Python is a command-line encryption tool, which uses an encryption mechanism very similar to One-time Pad (Duh. Thanks for telling that)


Install it using pip

$ pip install onetimepad


To use it from the command-line, run

$ onetimepad

Or, import the onetimepad module in your script

    #!/usr/bin/env python3

    import onetimepad

    cipher = onetimepad.encrypt('some text', 'a_random_key')
    msg = onetimepad.decrypt(cipher, 'a_random_key')


  1. The crypted message is very easy to crack if the length of key is less than the length of message.
  2. In any case, the key is not nescessarily random, which makes this tool as good as a toy.
  3. Thus, do not encrypt any real private stuff, it won’t protect you from the NSA. It is just a hack.
