utilities for generic SetKey and ExportKey operations on HMAC, RSA, ECC,
and AES. Add wc_ecc_size/wc_ecc_sig_size callback hooks for hardware-only
keys. Integrate into configure.ac as --enable-cryptocbutils=setkey,export
options with CI test configurations in os-check.yml.
Add test handlers in test.c and api.c with export/import delegation
pattern, small-stack-safe allocations, custom curve support, and
DEBUG_CRYPTOCB helpers.
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
* wc_rng_bank_default_set()
* wc_rng_bank_default_checkout()
* wc_rng_bank_default_checkin()
* wc_rng_bank_default_clear()
* Added additional argument error checking to existing APIs, with a new
rng_inst_matches_bank() helper function.
* Implemented feature gates WC_RNG_BANK_DEFAULT_SUPPORT and
WC_RNG_BANK_NO_DEFAULT_SUPPORT. When WC_RNG_BANK_DEFAULT_SUPPORT, the new
APIs are available, and a NULL bank passed to APIs implicitly refers to the
default bank.
wolfcrypt/test/test.c: in random_bank_test() add comprehensive smoke test coverage of new APIs and argument checking.
wolfssl/wolfcrypt/wc_port.h and wolfcrypt/src/wc_port.c:
* Add wolfSSL_RefInc2(), wolfSSL_RefDec2(), wolfSSL_RefWithMutexInc2(), and
wolfSSL_RefWithMutexDec2(), returning the atomically determined new count in
the second arg;
* Fix type of second arg in the fallback definition of
wolfSSL_Atomic_Ptr_CompareExchange().
linuxkm/lkcapi_sha_glue.c:
Refactor the _REGISTER_HASH_DRBG / _REGISTER_HASH_DRBG_DEFAULT facility around
the new wc_rng_bank_default facility, eliminating post-init use of
kernel-native crypto_default_rng, crypto_get_default_rng(), and
crypto_put_default_rng(), and eliminating all use on kernel 7.1+ (where these
will become unexported kernel-native statics). With the refactor, the
LINUXKM_DRBG_GET_RANDOM_BYTES facility uses only direct native wolfCrypt
objects and calls to fulfill requests.
wolfssl/wolfcrypt/error-crypt.h, wolfcrypt/src/error.c, wolfcrypt/test/test.c, tests/api.c: add WC_SUCCESS = 0 "wolfCrypt generic success".
* add WC_FIPS_186_4, WC_FIPS_186_4_PLUS, WC_FIPS_186_5, and WC_FIPS_186_5_PLUS feature macros.
* add support for WC_HASH_CUSTOM_MIN_DIGEST_SIZE, WC_HASH_CUSTOM_MAX_DIGEST_SIZE, and
WC_HASH_CUSTOM_MAX_BLOCK_SIZE, for use with custom digest algorithms.
* add SigOidMatchesKeyOid() helper function and WC_MIN_DIGEST_SIZE macro.
* add additional size and OID agreement checks for sig gen and verify ops.
* update ecc_test_vector() with FIPS 186-5 vectors.

- wolfSSL_i2d_OCSP_REQUEST_bio: save/restore pointer before i2d call
that advances it, preventing BIO_write from wrong offset and heap
corruption on free
- wolfSSL_d2i_OCSP_RESPONSE: remove (unsigned char) cast that truncated
pointer advance to 8 bits, breaking responses larger than 255 bytes
- wolfSSL_OCSP_CERTID_dup: deep-copy CertStatus to prevent double-free
when both original and duplicate are freed
- wolfSSL_i2d_OCSP_RESPONSE: add NULL check on response parameter
- wolfSSL_i2d_OCSP_REQUEST: advance *data pointer per i2d convention
- FreeOCSP: NULL-check ocsp->cm before dereferencing for heap
- Fix WOLFSSL_LEAVE strings to match actual function names in
wc_CheckCertOcspResponse, GetOcspEntry, GetOcspStatus,
CheckOcspResponse, CheckOcspRequest
Add test for CERTID dup (double-free confirmed under ASAN without fix)
and pointer advancement assertions for d2i_OCSP_RESPONSE callers.

unit.test.
sp_int.c:
Fixes to comments.
Added more define build options documentation to top of file.
Fixes for builds with WOLFSSL_SP_INT_NEGATIVE defined.
Fixes for when a->used is 0 and no underflow - not actually a problem
but cleaner code.
sp_sub has different checks on a->used when values are only positive.
sp_dic_2d missing check for e less than zero.
sp_to_unsigned_bin_len_ct: remove redundant check of outSz. Change i
to int to handle a->used of 0 and make code tidier.

Fix formatting in test.c.

- wolfSSL_X509_verify_cert: add host check from `ctx->param`
- wolfSSL_X509_verify_cert: Set `ctx->error_depth` on error
- Use WOLFSSL_-prefixed error constants (always available) instead of
OPENSSL_COEXIST-guarded macros, fixing error code mismatch in
coexist builds
- Set ctx->current_cert = orig on hostname/IP mismatch so error
reporting aligns with error_depth = 0 (leaf cert)
- Add IP address verification test cases (match + mismatch)
- Copy TLS 1.3 traffic secrets and DTLS 1.3 epoch/cipher state to the
write-dup side in DupSSL so key updates can be performed.
- Delegate KeyUpdate responses from the read side to the write side via
the shared WriteDup struct, for both peer-initiated and local key
updates.
- Delegate DTLS 1.3 ACK sending from the read side to the write side.
- Track DTLS 1.3 KeyUpdate ACKs: write side records the in-flight
KeyUpdate epoch/seq, read side sets keyUpdateAcked when the matching
ACK arrives.
- Delegate post-handshake certificate authentication (CertificateRequest
processing) from the read side to the write side, transferring
transcript hashes, cert context, and signature parameters.
- Reset prevSent/plainSz to prevent stale values from SendData to think
that data was already sent.
- Refactor FreeHandshakeHashes into Free_HS_Hashes for reuse.
- Move DTLS 1.3 epoch initialization earlier in InitSSL so the
write-dup early-return path has valid epoch state.
- Add tests for write dup with all protocol versions, key update,
post-handshake auth, and WANT_WRITE recovery.
- Add --enable-all --enable-writedup to CI os-check matrix.
wolfssl/ssl.h, examples/client/client.c, examples/server/server.c, src/bio.c, tests/api.c: add error tracing for WOLFSSL_SHUTDOWN_NOT_DONE.
tests/api.c: in test_wolfSSL_read_write_ex(), use WOLFSSL_SUCCESS rather than 1 for expected-success wolfSSL_shutdown()s, and add note that the wrong value is being returned (the test currently always fails, which is masked by an always-success retval).
- better ifdef's in hpke api.c tests
- updated ssl_ech.c to use wc_HpkeKemGetEncLen in both locations
- removed Ndh check in hpke.c, made it inline with the ecc cases
