Break rotational letter substitution (ROT) encoded text, right from your terminal.

Python substitute and transposition ciphers including Vigenère Cipher, Rail Fence Cipher, Caesar Cipher

CLI tool to Solve Substitution Ciphers using a wordlist

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

poor man's homophonic substitution cipher

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

Cryptography algorithms on C#

Crack one of the oldest Encryption Algorithms and reveal what is hidden in the ciphertext.

Cryptography Algorithm Implementations

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

Implementation of Ciphers

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.

Map English letters to unicode representing the Standard Galactic Alphabet

This repository contains my B.Tech project work on automatic solution to short substitution cipher using dictionary attack

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

This repository contains a Python implementation of HMM and MCMC methods for text decryption. These methods are applied for decrypting messages which have been encoded using a various ciphers.
