CryptoKit is a lightweight TypeScript library for secure key generation and encryption. It supports both symmetric and asymmetric cryptography, making it easy to build secure applications across any JavaScript environment.

QUIC-native TLS 1.3 implementation in Zig. RFC 8446/9001 compliant with zero external dependencies.

Leonardus is an open source project. It is a minimalist, stack-based programming system designed as a flexible framework for implementing and exploring algorithms. The syntax and semantics of its scripting language, LeoScript, are inspired by PostScript and Forth. It is extended with a prototype-based, object-oriented paradigm, has seamless integration into JupyterLab and Docker, and provides a concise and expressive environment for learning and experimentation.

The project name is a nod to Leonardus Pisanus, who was named and became known as Fibonacci.

Consult the project's GitLab Pages for documentation.

This is a high-performance public key GPU cracker designed to find a target HASH160 matching public key by brute-forcing a public key. It supports both CPU and GPU operation to meet different performance requirements. It is used in research projects such as Cyclone, Brainflayer, RCKangaroo, BitCrack, Ecloop, KeyHunt CUDA, and BitCrack.
