This is an encrypting and decrypting module. It uses a key to shift the letters by the key.
>>> from PyBitCrypt import pbc
>>> key = "ExampleKey1!"
>>> text = "ExampleText2?"
>>> pbc.encrypt(key, text)
'8af0c2dae0d8ca9fcaf1a55384'
>>> from PyBitCrypt import pbc
>>> key = "ExampleKey1!"
>>> encrypted = "8af0c2dae0d8ca9fcaf1a55384"
>>> pbc.decrypt(key, encrypted)
'ExampleText2?'
Enjoy!
