Cryptographic Algorithms

Cryptographic Algorithms is a Rust repository focused on implementing cryptographic algorithms from first principles.

Using minimal standard library methods to reveal the core logic and mathematics behind each function.

Installation

Make sure Rust and Cargo are installed.

git clone https://github.com/Lmpkessels/cryptographic-algos.git
cd cryptographic-algos
cargo test

cargo test will run all unit tests across SHA-256, HMAC, RIPEMD-160, and all other Cryptographic Algorithms.
