Perform HMAC-SHA1 and OTP challenges with YubiKey, OnlyKey and NitroKey, in pure Rust.

OAuth 1.0 header generation

HMAC authentication for Rails and HTTP Clients

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 Go implementation of RFC 4226 HOTP: An HMAC-Based One-Time Password Algorithm and RFC 6238: TOTP: Time-Based One-Time Password Algorithm

C implementation of Secure Hashing Algorithm-1.

HMAC-SHA1 implemented in POSIX shell script (without openssl)

TOTP, HOTP, HMAC-SHA1 implemented by MATLAB with test vector

SHA1, SHA2, SHA3, BLAKE2 and BLAKE3 functions written in pure Lua and optimized for speed

JavaScript implementation of HMAC generation and verification for the browser and node.js. It uses the global SubtleCrypto interface [Web Crypto API]. Multiple representations of the HMAC are available (e.g. hexadecimal, base32, base64, ...)
