Codec for one-time-pad style encryption

One Time Pad Codec

One-time pad encryption is a theoretically uncrackable encryption method based on a shared random key.

This codec can be used in three ways:

1. Include the class in your own code (onetime.py).
2. Use the codec from the command line (onetime.py).
3. Use the GUI (onetime_gui.py)

Running from the command line

# Encode a string
$ python onetime.py enc 'Hello, World!' 'my secret key'
> TC#Ds!}0H}vh

# Decode a string
$ python onetime.py dec 'TC#Ds!}0H}vh' 'my secret key'
> Hello, World!

# Provide a custom alphabet
$ python onetime.py enc 'Hello, World!' 'my secret key' 'abcdefghijklmnopqrstuvwxyz1234567890'
> m3l4scre8rvhy

Running the GUI

$ python onetime_gui.py

Creating windows exe

To create an EXE first make sure python is in your PATH environment variable.

Then install py2exe.

Finally put this in your command line:

python onetime_gui.py py2exe

The exe and accompanying files will be created in /dist.
