Implementation of various symmetric key encryption systems like AES, DES, triple DES (3 DES), Ceasar cipher, Substitution cipher, Hill cipher

poor man's homophonic substitution cipher

This is an implementation of all famous cryptography algorithms in python. There are several algorithm of cipher in this like Caesar, Transposition, Substitution, Vigenere, AES and RSA

A script for decrypting text encrypted with monoalphabetic/simple substitution ciphers using combined pattern deduction.

Program that encrypts plaintext and (attempts) to decrypt ciphertexts, encrypted via a mono-alphabetic substitution cipher. Replaces letters based on frequency / n-gram analysis. Tried to incorporate hill-climbing algorithm by measuring the fitness of resulting texts to find the best key.

This repository implements a variety of cryptographic methods and methods of breaking them
