HTTPDigest.Stream (HTTPDigest v0.1.0)

Incremental digest computation for large bodies.

This wraps :crypto.hash_init/1, :crypto.hash_update/2, and :crypto.hash_final/1 while preserving the same algorithm policy as the one-shot HTTPDigest.content_digest/2 API.

{:ok, stream} = HTTPDigest.Stream.init(algorithms: [:sha256])
stream = HTTPDigest.Stream.update(stream, chunk1)
stream = HTTPDigest.Stream.update(stream, chunk2)
{:ok, header_value} = HTTPDigest.Stream.content_digest(stream)
