Monoalphabetic Cipher in python

Implementation of Ciphers

Cryptographic application in C#

CHIPER is an interactive web platform for learning classical cryptographic techniques, featuring demos of algorithms like Monoalphabetic, Hill, Playfair, and more

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.

Implementation of various cipher algorithms

Monoalphabetic crypting/decrypting script written in plain Javascript.

GTU Information and Network Security ( INS ) in python .

In this program, we want to create an unlimited chatroom based on TCP/IP between the client and the server.

Solves substitution cipher algorithm on short text without spaces

This project contains implementation of some cryptography algorithms using C# language.

Python-based cryptographic tool that visually demonstrates the Monoalphabetic Cipher through an animated and interactive GUI built with tkinter. Tailored for educators, students, and researchers in cybersecurity, it transforms classical encryption into an engaging and insightful experienc

A program which performs a frequency analysis on a sample of English text and attempts a cipher-attack on polyalphabetic substitution ciphers using 2 famous methods - Kasiski's and Friedman's.
