polyalphabetic-cipher

Collection of '30' cryptography ciphers coded in JavaScript and an interface coded in HTML styled with CSS.

  The Bellaso cipher is a method of encrypting alphabetic text by using a series of interwoven Caesar ciphers, based on the letters of a keyword. It employs a form of [polyalphabetic substitution] (https://en.wikipedia.org/wiki/Polyalphabetic_cipher).

Cryptographic application in C#

A custom dual-table cryptographic utility designed to bypass automated pattern recognition and frequency analysis using dynamic index-parity substitution.

A C++ implementation of Practical Cryptography's Python Vigenère cipher breaker for improved speed, along with my own additions and features.

PolyAlphabetic Cipher

Encryption and decryption

implementation for encryption and Decryption with Private Key and Public Key

An encryption/decryption algorithm that makes use of Caesar and monoalphabetic substitution to encrypt/decrypt from files and write to files.

PolyAlphabitec Cipher in python

A genetic algorithm for breaking the Vigenère cipher using the DEAP evolutionary computation framework.

A polyalphabetic substitution cipher that encrypts/decrypts text using a keyword.

Cipher's Algorithms are basically techniques for encrypting data in a different ways

A simple and educational web application that demonstrates four classic encryption algorithms using only HTML, CSS, and JavaScript. This project is ideal for students and developers who want to learn the basics of cryptography through hands-on implementation.

Classical cryptanalysis C programs.
