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.
Remove WC_LMS_PARM_NONE as it serves no purpose.
Change sig_len from a 16-bit value to a 32-bit value in the parameters.
Added wc_LmsKey_SetParameters_ex() and wc_LmsKey_GetParameters_ex() to
handle hash algorithm.
Change mass ForceZeros to smaller amounts with XMEMSET and setting to
NULL or default valus.
Allow signing of empty message.
Other minor fixes.
Fix API tests to work when WOLFSSL_LMS_MAX_HEIGHT/WOLFSSL_LMS_MAX_LEVELS
are/is defined.
Copilot fixes:
- atmel.c: ATCA_ENABLE_DEPRECATED I2C path now uses ATECC_I2C_ADDR
instead of slave_address=1 (matches the non-deprecated path).
- atmel.c: capture and propagate atmel_createHandles() return value;
abort init via WC_HW_E if handle creation fails.
- atmel.h: include calib_aes_gcm.h with the same <calib/...> form used
for calib_command.h so a single -I (.../include or
.../include/cryptoauthlib) resolves both.
- configure.ac: drop the duplicated AM_CONDITIONAL([BUILD_CRYPTOAUTHLIB])
(kept only in the consolidated section near the end).
- settings.h: remove leftover commented-out '#ifdef WOLFSSL_ATECC508A'.
- benchmark.c: drop the broken TA100 wc_RsaSSL_Verify branch (it passed
message/enc as if they were sig/out).
- test.c: stop calling atmel_ecc_free() with the slot-TYPE enum
constants; wc_ecc_free(userA/userB) already releases the allocated
slots.
- ecc.c (microchip_curve_id_for_key): switch on key->dp->id, not size,
so SECP256K1 / BRAINPOOLP256R1 are not silently mapped to SECP256R1.
Helper is now defined for ATECC508A/608A as well, fixing the
TA100-only gating that broke ATECC builds.
- ecc.c (_ecc_make_key_ex): keep ATECC508A/608A's curve check at
SECP256R1-only (hardware does not support the wider curve set);
TA100 retains the multi-curve list.
Fenrir fixes:
- ecc.c (wc_ecc_init_ex): under TA100 + ALT_ECC_SIZE the pubkey x/y/z
pointers must be aimed at key->pubkey.xyz[] (with alt_fp_init) before
mp_init_multi - otherwise mp_init_multi dereferenced NULL.
- atmel.c (atmel_get_rev_info): check atcab_wakeup return and bail out
via atmel_ecc_translate_err before calling atcab_info.
- atmel.c (atmel_ecc_create_pms, TA100+ECDH_ENC): pass
MAP_TO_HANDLE(slotId) (the ephemeral private-key handle) into
talib_ecdh_compat instead of MAP_TO_HANDLE(slotIdEnc).
- atmel.c (wc_Microchip_rsa_create_key): on any failure after the first
talib_create_element succeeds, delete the previously created
handle(s) and clear rKeyH/uKeyH so device elements are not leaked.
- aes.c (wc_AesGcmEncrypt / wc_AesGcmDecrypt TA100 fast paths): replace
'(authInSz + sz) <= MAX' with bounds on each operand individually so
word32 wraparound cannot bypass the 996-byte hardware limit.
- rsa.c (RsaPrivateDecryptEx): drop the TA100 RSA_PUBLIC_DECRYPT
short-circuit. wc_Microchip_rsa_verify expects (digest, digestLen,
sig, sigLen, ...) and the verified flag must be honored; the proper
TA100 fast-path already lives in wc_RsaPSS_CheckPadding_ex2.
Replace the liboqs-based pre-standardization SPHINCS+ implementation
with the native FIPS 205 SLH-DSA implementation across the
certificate / ASN.1 / X.509 layers, and add SLH-DSA-rooted test
certificates plus TLS 1.3 .conf scenarios that exercise the new
verification path. All liboqs SPHINCS+ code is removed.
This enables SLH-DSA for certificate chain authentication: CA
certificates signed with SLH-DSA, certificate signature verification
against an SLH-DSA root. TLS 1.3 entity authentication via
CertificateVerify with SLH-DSA will be added in a follow-up PR.
Follows RFC 9909 (X.509 Algorithm Identifiers for SLH-DSA) and
NIST FIPS 205. Supports both SHAKE and SHA-2 parameter families
across all twelve standardized variants.
DER codec:
- New PrivateKeyDecode, PublicKeyDecode, KeyToDer, PrivateKeyToDer,
PublicKeyToDer with RFC 9909 encoding (bare OCTET STRING containing
4*n raw bytes = SK.seed || SK.prf || PK.seed || PK.root, no nested
wrapper). OID auto-detection across all twelve SHAKE / SHA-2 variants.
- PublicKeyDecode raw-bytes fast path mirrors wc_Falcon_PublicKeyDecode
and wc_Dilithium_PublicKeyDecode so callers (notably
wolfssl_x509_make_der and ConfirmSignature, which pass the raw
BIT STRING contents stashed by StoreKey) decode correctly. Honours
the caller's *inOutIdx start offset.
- Error paths in Private/PublicKeyDecode preserve params/flags/
inOutIdx and only ForceZero the buffer half each helper actually
writes; skip the wipe entirely on BAD_LENGTH_E (no bytes touched).
- ImportPublic uses |= on flags so a Private-then-Public import
sequence retains FLAG_PRIVATE.
OID dispatch:
- 12 standardized NIST OIDs (6 SHAKE + 6 SHA-2) per RFC 9909. The
pre-standardization OID-collision mechanism is removed since NIST
OIDs do not collide.
- wc_SlhDsaOidToParam / wc_SlhDsaOidToCertType return NOT_COMPILED_IN
(rather than -1) for recognised SLH-DSA OIDs whose parameter set
isn't built; wc_IsSlhDsaOid recognises both. The x509 dispatch
surfaces this as a precise diagnostic instead of the generic
"No public key found".
- wc_GetKeyOID picks a placeholder parameter from whatever variant is
compiled in and #errors at compile time if none is.
- asn_orig.c EncodeCert / EncodeCertReq accept SHA-2 SLH-DSA keyTypes
alongside SHAKE.
Tests and fixtures:
- Test cert chain in certs/slhdsa/: SLH-DSA-SHAKE-128s and
SLH-DSA-SHA2-128s self-signed roots that sign reused ML-DSA-44
entity keys (server + client), plus the gen script
(gen-slhdsa-mldsa-certs.sh, OpenSSL >= 3.5).
- New TLS 1.3 .conf scenarios under tests/suites.c dispatch:
test-tls13-slhdsa-shake.conf, test-tls13-slhdsa-sha2.conf, and a
wrong-CA negative test test-tls13-slhdsa-fail.conf.
- DER round-trip and on-disk decode tests; bench_slhdsa_*_key.der
fixtures regenerated with wolfSSL's own encoder so the codec is
pinned to RFC 9909.
- New unit test test_wc_slhdsa_x509_i2d_roundtrip exercises the raw
PublicKeyDecode entry point that wolfssl_x509_make_der relies on.
- test_wc_slhdsa_check_key now tests both Public-then-Private and
Private-then-Public import orderings.
Build / ABI:
- DYNAMIC_TYPE_SPHINCS = 98 kept as RESERVED with a tombstone comment
for ABI stability; new code should use DYNAMIC_TYPE_SLHDSA (107).
- All build system / IDE project files updated; SPHINCS+ sources,
headers, and test data removed.
- Dead bench_slhdsa_*_key arrays removed from gencertbuf.pl and
certs_test.h; the .der files on disk drive the decode tests.
