futoin/util-js-hkdf

The futoin/util-js-hkdf project is a Node.js implementation of the HMAC-based Extract-and-Expand Key Derivation Function (HKDF) as specified in RFC5869, with additional support for the HKDF-Expand-Label variation from RFC8446 (TLS v1.3). It is designed for developers needing secure key derivation in Node.js applications, offering high performance, compliance with RFC test vectors, and support for arbitrary hash functions. The library is particularly useful for cryptographic operations requiring robust key management, such as TLS implementations or secure data encryption.
