A Lightweight Partially Homomorphic Encryption Library for Python

Constantine: modular, high-performance, zero-dependency cryptography stack for proof systems and blockchain protocols.

Practical Cryptography for Developers: Hashes, MAC, Key Derivation, DHKE, Symmetric and Asymmetric Ciphers, Public Key Cryptosystems, RSA, Elliptic Curves, ECC, secp256k1, ECDH, ECIES, Digital Signatures, ECDSA, EdDSA

🧠 💡 📈 A project based in (Classical) Post-Quantum Cryptography, namely in Lattice-Based Cryptography. This project was built using Jupyter Notebook, SoS (Script of Script) Notebook, Java, Python, Bouncy Castle library, and TeX. The goal of the project was the study and analysis of the CRYSTALS public-key (asymmetric) cryptographic suite.

A cryptographic library

Another wrapper around ZeroMQ's Pub-Sub with Curve+ZAP, over Tor. Provides peers, each identified by public key, onion address, and port, that publish vec<vec<u8>> data under topics to which other peers subscribe to receive respective data. Rust version.

High-level API binding to low-level crypto APIs in golang

An Authentication library for FishNet networking solution.

This repository will be storing the code required in allowing public key authentication.

Samples of RSA (Rivest–Shamir–Adleman) asymmetric cipher implementations in Rust

Python library for Elliptic Curve Cryptography: key exchanges (Diffie-Hellman, Massey-Omura), ECDSA signatures, and Koblitz encoding. Suitable for crypto education and secure systems.

Rust bindings for liboqs

Gestalt strives to be a fairly comprehensive cryptography library in C++ which provides developers with many published ciphers, hashing functions, public key cryptography and more.

Documentation for Polykey

A java text editor and email client for public key cryptography and encryption. The ciphers use hypercomplex and hyper-dimensional numbers (including vectors, quaternions, matrices, cubes, and tesseracts), polynomials, determinants, multi-variable, multi-equation, and multi-dimensional arithmetic, and Merkle-Hellman knapsacks.

OPTIGA™ Trust M Software Framework

Implementation and analysis of a public-key encryption system with permutations conceptually similar to the Merklee-Hellman knapsack cryptosystem.
