createHash, createHmac, crypto.hash, pbkdf2, pbkdf2Sync, hkdf and hkdfSync accept every digest crypto.getHashes() lists in Node 24: SHA-512/224, SHA-512/256, SHA-256/192, SHA3-224 to SHA3-512, Keccak-224 to Keccak-512, SHAKE128, SHAKE256, KECCAK-KMAC-128, KECCAK-KMAC-256, RIPEMD-160, BLAKE2b-512, BLAKE2s-256, SM3 and MD5-SHA1. The new runtime unit scr_hash.c implements Keccak, RIPEMD-160, BLAKE2b, BLAKE2s and SM3, and is registered in both runtime pack matrices and the C-compile path. Names resolve as Node 24.22 resolves them: case-insensitively, with OpenSSL's provider aliases and object identifiers, ending at the first NUL, and with trailing spaces allowed except on the RSA signature aliases. "dss1" and "DSS1" are SHA-1, and createHash and crypto.hash accept "dss1" in any case. The compiler no longer refuses literal digest names outside SHA-1/SHA-2 and MD5; unknown names throw Node's errors at run time. SHAKE and KMAC digests use their default output lengths. createHmac rejects them with Node's OpenSSL error, pbkdf2 with "xof digests not allowed", and hkdf with "Deriving bits failed". pbkdf2 with a key length of 0 now fails with "Deriving bits failed" as in Node 24.22, and the callback forms pass these failures to the callback. PBKDF2 computes the keyed HMAC states once instead of on every iteration, and digest contexts are cleared with memset and a compiler barrier instead of a byte loop. The Keccak permutation, the RIPEMD-160 and BLAKE2 compression functions and the SM3 rounds are unrolled with constant indices.
