Elliptic Curve Cryptography and Common Public Key Cryptography Implementations

👻 Post-quantum cryptography for Python.

MSc Module

A Rust implementation of CPace, a balanced PAKE.

EDHOC (RFC 9528): Lightweight authenticated key exchange in C for constrained IoT devices, post-quantum ready

The aim is to allow Alice and Bob to generate a secure private key that can be used for the one-time pad without having to meet privately.

This repository offers a thorough explanation of the Diffie-Hellman export grade attack, accompanied by a demo.

Diffie-Hellman key agreement with RFC 3526 2048-bit MODP groups and HKDF derivation

Diffie-Hellman key agreement with RFC 3526 2048-bit MODP groups and HKDF derivation

🤝 Mutually authenticating key agreement to establish shared secrets over an insecure channel.

Herradura is a crytpographic suite (library+cli) based on bitwise, iterative and periodic functions (FSCX) + known cryptographic constructions. It includes key-exchange, symmetric encryption, public key encryption and digital signature algorithms, with post-quantum algorithms and security proofs..

An encryption/decryption algorithm based on Lorenz's Strange Attractor

Post-quantum Noise protocol framework for Go. NQ, PQ (ML-KEM, HQC), Hybrid, DualLayer handshakes. ML-DSA-65 + SLH-DSA signing (FIPS 203/204/205). 90 patterns, 18 SLH-DSA param sets (SHA2/SHAKE/BLAKE3). Verified against Rust Clatter + NIST ACVP vectors.

Joux's tripartite key-exhange using curve BLS12-381

Simple project which aimed to implement the signal protocol in go, it was abandoned.
