A cryptography library

A simple and fast Vigenère solver using Index of Coincidence, Friedman and Chi-squared

PyLock is a password manager that allows users to securely store and retrieve their passwords. It uses encryption to ensure that the stored passwords are safe and protected.

🔢 A python version of Enigma Machine

Caesar Cipher Project for Cryptography Class

AES is a symmetric encryption algorithm standardized by the National Institute of Standards and Technology (NIST). It operates on fixed block sizes of 128 bits and employs a 128-bit key to encrypt and decrypt data securely. AES is widely used for securing sensitive data due to its strong encryption, efficiency, and resistance to most known attacks

Feistel cypher based on TwoFish and SkipJack. Not my design, although I did write the code.

SignLedger is a production-ready Python library for immutable audit logging with cryptographic verification. Built for compliance, security, and trust, SignLedger provides blockchain-inspired tamper-proof logging for critical applications.

PlayFair cypher implemented using JAVA

Image Encryption – Python Project A basic image encryption and decryption tool built using Python. This project manipulates pixel values (e.g., swapping or modifying them mathematically) to obscure and recover the original image. A great intro to image processing and basic cryptographic techniques!

Data cryptography in frontend with crypto.js

This is a Text Encrypter/Decrypter program written in Python which uses the Caesar Cipher technique to encrypt the text.
