about

hmac_sha512.nx -- HMAC-SHA-512 (RFC 2104 / FIPS 198-1). license_tier: INDEPENDENT_REDERIVE genealogy_id: international-research-sources/nist/fips_198_1 Completes the HMAC family: SHA-256, SHA-384, SHA-512. Used where TLS cipher suites or key-derivation ladders want the full 512-bit MAC width (relatively rare, but present in some SSH / OpenPGP / JWT profiles). Differences from hmac.nx: - Block size B = 128 bytes (SHA-512 block), not 64. - Hash output = 64 bytes (SHA-512), not 32. - Uses sha512_init instead of sha256_init.
