Sodium HMAC Utility

sodium-hmac is a JavaScript utility library for creating Hash-based Message Authentication Codes (HMAC). Currently at stable version 2.1.0, this package provides both a streaming API for processing data in chunks and a simplified one-shot API for common SHA256 and SHA512 HMAC operations. Its key differentiator is the flexibility to integrate custom hash functions, provided they adhere to a specific interface (init, update, final, BYTES, STATEBYTES), allowing users to leverage various cryptographic primitives like Blake2b via external libraries such as `sodium`. Maintained by the Holepunch ecosystem, it focuses on reliable cryptographic primitives for secure data integrity and authentication. The library does not enforce specific external dependencies for its hash functions, making it adaptable to different environments and cryptographic backends.
