The 28-byte BLAKE2b behind Cardano's addresses: payment key hashes, stake key hashes, script hashes. Like BLAKE2b-256, the length is part of the computation, not a cut afterwards.

Hash the key's bytes, so a key you hold as hex goes in through Uint8Array.fromHex or inputEncoding: "hex". No HMAC mode.
