Refactor CMAC init to common function, add wc_AesNew_Id/Label API, do same for RSA new
functions, and add test init helpers for id[] support along with some test disable options
Introduce the WOLFSSL_MLKEM_DYNAMIC_KEYS option to allow dynamic allocation
of private and public key buffers in the MlKemKey struct. This change
enables right-sizing of buffers based on the actual ML-KEM level and eliminates
unnecessary memory usage for encapsulate-only operations.
The WOLF_CRYPTO_CB_FREE path in wc_MlKemKey_Free, wc_dilithium_free,
and wc_ecc_free returned early when the crypto callback succeeded,
skipping local cleanup: ForceZero on private key material, PRF/hash
object frees (ML-KEM), SHAKE free and cached vector frees (ML-DSA),
and mp_forcezero on the private scalar and all hardware port frees
(ECC).
Any non-PKCS#11 callback returning 0 would silently leave key material
in memory. The PKCS#11 backend worked around this by returning
CRYPTOCB_UNAVAILABLE on success to force the fallthrough — a fragile
contract that is not part of the documented callback interface.
Fix by always continuing to software cleanup after invoking the
callback.
Remove the CRYPTOCB_UNAVAILABLE workaround from the three PKCS#11 free
dispatchers (ECC, ML-DSA, ML-KEM); they now return the real result of
C_DestroyObject.
Add PKCS#11 integration for ML-KEM with key generation,
encapsulation and decapsulation support through the crypto
callback path.
Includes ML-KEM PKCS#11 constants/types, key store handling,
token object lifecycle management, and ML-KEM key init helpers
for private-key ID/label workflows.
Align implementation details with current upstream conventions
and review feedback:
- internal wolfCrypt ML-KEM path only for PKCS#11
- inline ML-KEM key-type/flag checks in PKCS#11 code
- proper key template formatting and enum placement
- ensure TLS ML-KEM object storage behavior is compatible with
PKCS#11 ephemeral-key decapsulation flow
Fixed wc_AesEaxAuthDataUpdate to check eax for NULL before
dereferencing.
Fix AesSivCipher to delete/free AES if new/initialization succeeded.
Memsetting to 0 doesn't work when WC_DEBUG_CIPHER_LIFECYCLE is defined.
Added tests for:
- AES-EAX streaming
- AES-SIV
- Poly1305
- DES-CBC
* implement legacy compatibility in settings.h and configure.ac (adds --enable-blake2b while retaining --enable-blake2);
* fix incorrect Blake2 gates in wolfcrypt/src/hash.c wc_HashGetDigestSize() and wc_HashGetBlockSize();
* in wolfcrypt/test/test.c hash_test(), backfill missing Blake2 test coverage and separate blake2b from blake2s in typesHashBad[];
* in tests/api/test_hash.c, separate blake2b from blake2s in notCompiledHash[], sizeSupportedHash[], and sizeNotCompiledHash[].
Replace single last-byte padding check with full PKCS#5/PKCS#7
validation: verify padLen is non-zero and within block size.
Both wc_PKCS7_DecodeEnvelopedData and wc_PKCS7_DecodeEncryptedData
paths are fixed.
Add check before word32 addition in dilithium_hash256() that
could wrap to zero, bypassing the size check.
Also reject absurdly large msgLen (> UINT32_MAX/2) in
wc_dilithium_verify_ctx_msg.
Save key->heap before calling wc_*_free(), which zeros the entire key
structure via ForceZero. The saved heap pointer is then passed to XFREE
instead of the now-zeroed key->heap.
OCSPBASICRESPASN_IDX_SIGNATURE_PARAMS is only defined when WC_RSA_PSS
is enabled but was used unconditionally in EncodeBasicOcspResponse,
causing a build error when WC_RSA_PSS is not defined.
