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.
- Reduce long keys in a separate state rather than reusing the state used
for the HMAC inner hash.
- Pad the rest of the buffer with zeros as required by the spec.
- Add regression tests
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.
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.
- atmel.c: restore the closing #endif for the outer
WOLFSSL_ATMEL/ATECC/TA100 block. The previous "duplicate
ATCA_TFLEX_SUPPORT" cleanup removed the real closer because the
trailing-comment was misleading, leaving the file with an
unterminated #if from line 35.
- ecc.c: drop !defined(WOLFSSL_MICROCHIP_TA100) from the guard around
wc_ecc_point_is_at_infinity. The function is generic
(mp_iszero(x) && mp_iszero(y)) and call sites in
_ecc_import_x963_ex2 and friends don't exclude TA100, so the
TA100 build was failing to link.
