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.

PoW Blockchain network built in C#. Supports the ZR420 cryptocurrency. Supports decentralised storage and transaction forwarding through peer-2-peer networking.

Ce projet met en œuvre des techniques de cryptanalyse, des heuristiques d'identification sophistiquées et une architecture logicielle robuste pour résoudre des missions de déchiffrement complexes.

Python implementation of RSA cryptosystem showing the encryption and decryption algorithms as well as the possible attacks.

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

A Python implementation of the Caesar Cipher algorithm for encrypting and decrypting text using classical cryptography techniques.

A cryptography library

A prototype security system that acts as a "Privacy Wrapper" for identity verification gateways. It uses an Isolation Forest machine learning model to distinguish between legitimate user activity and malicious intent (such as data scraping or brute-force attacks), featuring a real-time monitoring dashboard and an attack simulation tool.

🔢 A python version of Enigma Machine

MCP server exposing cryptography library functionality.

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

Firefox extension for PQC readiness checks: shows the TLS version and key exchange of every site and resource - traditional, hybrid post quantum (PQ/T, e. g. X25519MLKEM768) or pure post-quantum (e. g. ML-KEM-1024).

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