crypyto

crypyto [kri-pahy-toh] is a Python package that provides simple usage of cryptography tools and ciphers on your programs.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites

Python >= 2.7 / Python >= 3.0
Python packages:
- (unidecode)[https://pypi.org/project/Unidecode/] to normalize strings

You can install unidecode with pip:

pip install unidecode

Installing

For now, you can clone this repository using git

git clone https://github.com/yanorestes/crypyto.git

Usage

Ciphers crypyto supports:

Polybius Square

>>> from ciphers import PolybiusSquare
>>> ps = PolybiusSquare(width=5, height=5)
>>> ps.encrypt('EncryptedMessage')
'5x5#5-1;3-3;3-1;2-4;4-5;5-3;4-4;5-1;4-1;2-3;5-1;3-4;3-4;1-1;2-2;5-1'
>>> ps.decrypt('5x5#5-1;3-3;3-1;2-4;4-5;5-3;4-4;5-1;4-1;2-3;5-1;3-4;3-4;1-1;2-2;5-1')
'ENCRYPTEDMESSAGE'

Atbash

>>> from ciphers import Atbash
>>> atbash = Atbash()
>>> atbash.encrypt('Hello, world!')
'SVOOL, DLIOW!'
>>> atbash.decrypt('SVOOL, DLIOW!')
'HELLO, WORLD!'

Caesar cipher

>>> from ciphers import Caesar
>>> caesar = Caesar(key=5)
>>> caesar.encrypt('Hello, world!')
'MJQQT, BTWQI!'
>>> caesar.decrypt('MJQQT, BTWQI!')
'HELLO, WORLD!'
>>> caesar.brute_force('MJQQT, BTWQI!')
NKRRU, CUXRJ!
OLSSV, DVYSK!
...
HELLO, WORLD!
IFMMP, XPSME!
...

ROT13

>>> from ciphers import ROT13
>>> ROT13.encrypt('Hello, world!')
'URYYB, JBEYQ!'
>>> ROT13.encrypt('URYYB, JBEYQ!')
'HELLO, WORLD!'
