wc_SlhDsaKey_{Sign,Verify}Hash* previously accepted the raw message and
performed the pre-hash internally. They now require the caller to hash the
message first and pass the resulting digest -- the functions no longer call
wc_*Hash() themselves and feed the supplied digest directly into the M'
construction. Parameters are renamed from msg/msgSz to hash/hashSz to reflect
this, and hashSz is validated against wc_HashGetDigestSize(hashType) per
FIPS 205 Section 10.2.2 (32 for SHAKE128, 64 for SHAKE256), returning
BAD_LENGTH_E on mismatch.
This matches ML-DSA's wc_dilithium_{sign,verify}_ctx_hash, NIST ACVP
signatureInterface=external / preHash=preHash vectors, and other libraries
(OpenSSL HASH-ML-DSA, leancrypto, mldsa-native). It also enables distributed
signers and HSM-style flows where the digest is computed separately from the
signing operation.
Migration: callers must now hash the message before invoking these APIs;
passing the raw message will either fail length validation or produce
signatures over the wrong input. The M'-supplied wc_SlhDsaKey_SignMsg* /
VerifyMsg family (FIPS 205 internal interface, Algorithms 19/20) is
unchanged but gains stricter input validation and doxygen coverage.
tests/api/test_mldsa.c: fix misplaced PRIVATE_KEY_UNLOCK() in dilithium_oneasymkey_version_check();
wolfcrypt/test/test.c: fix valgrind-detected "Conditional jump or move depends on uninitialised value(s)" in ecc_test_curve_size() negative test on all-zeros digest.
Wire the stateful hash-based signature schemes HSS/LMS (RFC 8554) and
XMSS / XMSS^MT (RFC 8391) into the X.509 cert-verification path per
RFC 9802.
asn:
- Register id-alg-hss-lms-hashsig (1.2.840.113549.1.9.16.3.17),
id-alg-xmss-hashsig (1.3.6.1.5.5.7.6.34) and id-alg-xmssmt-hashsig
(1.3.6.1.5.5.7.6.35) in oid_sum.h, asn.c and asn1_oid_sum.pl.
- Plumb the new keyOIDs through GetCertKey, SigOidMatchesKeyOid,
HashForSignature, FreeSignatureCtx and ConfirmSignature so leaf
and CA certificates parse, load and verify end-to-end.
- Rename IsSigAlgoECC -> IsSigAlgoNoParams; the function has tested
"AlgorithmIdentifier omits NULL parameters" since PQC algos were
added, and HSS/LMS + XMSS only made the original name more
misleading.
wc_lms / wc_xmss:
- Add wc_XmssKey_ImportPubRaw_ex which derives parameters from the
4-byte OID prefix at the start of the raw public key, taking an
is_xmssmt hint to disambiguate the overlapping XMSS / XMSS^MT OID
spaces.
- Extend wc_LmsKey_ImportPubRaw with the same auto-derive from
u32str(L) || lmsType || lmOtsType when key->params is NULL; this
also fixes a latent NULL-deref when the legacy precondition was
violated.
- Reject WC_*_STATE_OK in both ImportPubRaw paths so re-importing
on a private-key-loaded handle can't desync priv/pub.
- Tighten wc_XmssKey_Verify's length check to strict equality,
matching wc_LmsKey_Verify and the documented contract of using
wc_XmssKey_GetSigLen for the buffer size.
tests / fixtures:
- Bouncy Castle 1.81 fixtures in certs/lms and certs/xmss covering
every supported parameter set, plus CA->leaf chains per family
and one BC-native LMS fixture as a cross-impl interop gate.
- New api tests verify each fixture end-to-end, tamper TBS and
signature bytes, exercise the wolfCrypt-level negative paths
(NOT_COMPILED_IN, BUFFER_E, BAD_FUNC_ARG, BAD_STATE_E, OID/family
mismatch, partial-write invariants, lenient VERIFYONLY re-import,
strict sigLen check) and confirm the outer signatureAlgorithm
OID is rejected when it disagrees with the SPKI in both
XMSS<->XMSS^MT directions.
Only have the public key in the ML-DSA key object when verify-only.
Be able to leave out SHA-3 APIs when only needing SHAKE.
Fix ML-DSA testing to only have data for compiled in parameters.
wolfcrypt/test/test.c: in aes_cbc_test(), use unconditional static on msg4 and verify4 to work around gcc optimizer bug (probably same bug as noted in ac11279c60).
- x509_str: require CA:TRUE unconditionally in wolfSSL_X509_verify_cert;
verify leaf signature even when verify_cb overrides INVALID_CA
- x509_str: align WOLFSSL_X509_V_ERR_INVALID_CA with OpenSSL value (79)
so OPENSSL_COEXIST builds compile; bump WC_OSSL_V509_V_ERR_MAX to 80
and extend error_test() missing-value table for the new gaps
- asn: reject embedded NUL in dNSName / rfc822Name / URI SAN entries
- internal: re-verify restored ticket peer cert against trust store with
CRL/OCSP checks; clear stale state from session cache on verification
failure
- ticket: bind SNI and ALPN into session ticket via compile-time selected
hash (TICKET_BINDING_HASH_TYPE); reject resumption on mismatch in both
TLS 1.3 and TLS 1.2 paths
- ticket: defer SNI/ALPN binding check until after extensions are parsed
by consolidating into VerifyTicketBinding(), called once after
ALPN_Select in DoTls13ClientHello and DoClientHello; the early
per-call sites ran before extensions were parsed and rejected valid
resumptions in nginx, haproxy, grpc, and CPython integration tests
- ssl_sess: free previous session in wolfSSL_d2i_SSL_SESSION before
overwrite
- examples/client: increase SESSION_TICKET_LEN fallback from 256 to 2048
to support larger tickets
- tests: update SAN NUL fixtures and add parse-time rejection coverage;
add test_tls13_ticket_peer_cert_reverify for CA-removal scenario; skip
it under WOLFSSL_NO_DEF_TICKET_ENC_CB
