about

nx_hkdf_sha384_wasm.nx -- HKDF-SHA-384 (RFC 5869) for WAT target. Built on inline HMAC-SHA-384 (= SHA-512 compression + SHA-384 IV + 48-byte truncation). PRK length = 48 (one HMAC-SHA-384 output); HashLen = 48; max OKM = 255 * 48 = 12,240 bytes. Used in the TLS 1.3 key schedule when the ciphersuite is TLS_AES_256_GCM_SHA384. API: nx_hkdf384_extract(salt, salt_len, ikm, ikm_len, scratch, prk_out) nx_hkdf384_expand(prk, info, info_len, okm_len, scratch, okm_out) Verified vs RFC-style cross-check against Node OpenSSL HKDF-SHA-384. license_tier: INDEPENDENT_REDERIVE genealogy_id: international-research-sources/ietf/rfc_5869 + rfc_4231 lineage_id: nishi_hkdf_sha384_wasm_q1 safe_shift_audit: rotr-style (shift exponent = nn, mask exponent = 64-nn; differs -> safe)
