hmac(…) → String

Kind · scalar

Computes a keyed digest over the message and returns lowercase hex. Accepted algorithms: sha256 (default), sha1, sha224, sha384, sha512, sha512_256, md5, keccak256, and crc32. The block size follows the underlying hash (64 for md5/sha1/sha224/sha256, 128 for the sha512 family, 136 for keccak256), so hmac(msg, key, 'sha256') matches the RFC 4231 test vectors.

Part of the Hash & Crypto family.

crc32

Computes a CRC-32 checksum of the input bytes. This is intended for integrity checks, not for cryptographic security.

keccak256

Computes a Keccak-256 digest for each input value and returns lowercase hexadecimal text.
