HMAC authentication for Rails and HTTP Clients

Go JWT signing, verifying and validating

Secure Multi-Party Computation (MPC) with Go. This project implements secure two-party computation with Garbled circuit protocol.

A standalone Java 7 implementation of HMAC-based key derivation function (HKDF) defined in RFC 5869 first described by Hugo Krawczyk. HKDF follows the "extract-then-expand" paradigm which is compatible to NIST 800-56C Rev. 1 two step KDF

A crypto portfolio written in Flutter. It supports Binance, Bittrex, HitBTC, Coinbase, Coinbase Pro and Mercatox

Securely store WordPress user passwords in database with Argon2i hashing and SHA-512 HMAC using PHP's native functions.

CryptGuard is a comprehensive cryptographic library, offering robust encryption and decryption capabilities. It integrates traditional cryptography with post-quantum algorithms, ensuring resilience against quantum computing threats.

Goexl签名框架集成，提供常见的签名验签操作

A .NET implementation of HMAC, with support for SHA256, SHA384, and SHA512.

A .NET implementation of HKDF, with support for SHA256, SHA384, and SHA512.

A Password in Hash Format is the output of applying a cryptographic hash function (such as HMACSHA256 or HMACSHA512) to a password (plus salt).

HMAC stands for Hash-Based Message Authentication Code. It is a security mechanism used to verify the integrity and authenticity of a message exchanged between a client and a server.
