This repository contains a collection of ciphers and encryption applications implemented in Python. The ciphers include classic ciphers like Caesar Cipher, Vigenere Cipher, Playfair Cipher, etc. The encryption applications include tools for encryption and decryption of messages, password generators, and more.

Powerful, open source licensing system, written asynchronous in .NET Core

Final Project – COAL, Summer 2023, FAST NUCES. Built Vigenère, ROT13, Rail Fence ciphers, and Diffie-Hellman in Irvine32 Assembly, showcasing low-level string handling and modular arithmetic.

A robust cryptographic tool developed in MATLAB, combining AES-128, Vigenère, and Row Transposition.

A Python implementation of the DES algorithm featuring bitwise operations and a comparison between ECB and CBC encryption modes for secure file handling.

project contain implementation of security algorithms encryption and decryption methods

A modernized archive of cryptographic simulations including GSM Security (A3/A8, A5/1), DES, and Whirlpool hashing, updated for Java 21.

Poorman's Security Algorithm

C-based security system simulation that converts sensor data to binary using parity checks and calculates a decimal security code.

🔐 Implement the Playfair cipher in Python to learn classical digraph encryption and matrix-based substitution techniques clearly and simply.
