HKDF is an HMAC key derivation function implementation written in Rust.

Overview

This library implements an HMAC based key derivation function (HKDF) written in Rust. It can be used to derive cryptographically strong pseudorandom keys, and support protocols like TLS (where a shared secret is used to derive a shared key between a client and server).
