ROSET Graphical (ROS Encryption Tool) is an easy-to-use encryption tool that provides full access to the experimental SAS-RCS and SAS-RBS encryption algorithms. It supports both text and file encryption.
Break rotational letter substitution (ROT) encoded text, right from your terminal.
Python substitute and transposition ciphers including Vigenère Cipher, Rail Fence Cipher, Caesar Cipher
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.
Cryptography algorithms on C#
This repository contains my B.Tech project work on automatic solution to short substitution cipher using dictionary attack
Cryptography Algorithm Implementations
Implementation of Ciphers
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.
Map English letters to unicode representing the Standard Galactic Alphabet
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
A Python implementation of the classical Playfair cipher with encryption and decryption support. Built for educational purposes to understand digraph substitution and historical cryptographic techniques.
A repository which contains the implementation of Ceasers Cipher which is a very basic and most common data encryption Technique in C++.
A side project developed for Experiment 2 of Security Lab, Design & implementation of a product cipher using substitution and transposition Ciphers. The link to the website is given below. Have fun!
A custom dual-table cryptographic utility designed to bypass automated pattern recognition and frequency analysis using dynamic index-parity substitution.
