Python Playfair Implementation
I've been playing around with the Playfair cipher recently, so I thought it would be a fun little project to write a Python class that can encrypt and decrypt according to the Playfair cipher, so that's exactly what I did.
If you haven't heard of the Playfair cipher, check out my other post about how it works.
As I said before, the class is written Python. I wrote it in Python 2.6 on a Windows 7 machine.
I have a GitHub repository set up for the project.
The current version of this class is version 1.0. Features include:
- You can set the password you would like to encrypt and decrypt with.
- You can set the omission rule used to generate the 5 by 5 matrix. Current omission rules are:
- Replace J with I
- Omit Q
- Replace I with J
- Set what character you would like to use to pad double letter digraphs and odd length inputs.
Here is an example script to demonstrate how easy it is to use...
.. and the output.
