wolfssl/wolfcrypt/hash.h: when WOLFSSL_NOSHA512_{224,256}, gate out prototypes for wc_Sha512_{224,256}Hash[_ex](), to shift build failures from link-time to compile-time.
* allow for fips-dev in v7|ready|dev ENABLED_SHA256_DRBG and ENABLED_SHA512_DRBG setup and change from AC_MSG_WARN to AC_MSG_ERROR if user tries to disable outside fips-dev;
* set ENABLED_SHA512_DRBG=no in lean-aesgcm setup;
wolfcrypt/test/test.c: suppress concurrency-mt-unsafe in myFipsCb();
.wolfssl_known_macro_extras: fix lexical order.
Add SRAM PUF (Physically Unclonable Function) support to wolfCrypt. Derives device-unique cryptographic keys from the power-on state of SRAM memory using a BCH(127,64,t=10) fuzzy extractor with HKDF key derivation.
- **wolfCrypt PUF API** (`wolfcrypt/src/puf.c`, `wolfssl/wolfcrypt/puf.h`)
- `wc_PufInit`, `wc_PufReadSram`, `wc_PufEnroll`, `wc_PufReconstruct`
- `wc_PufDeriveKey` (HKDF-SHA256), `wc_PufGetIdentity` (SHA-256 device fingerprint)
- `wc_PufZeroize` (secure context cleanup)
- `wc_PufSetTestData` (synthetic SRAM for testing without hardware)
- **BCH(127,64,t=10) error-correcting codec** - corrects up to 10 bit flips per 127-bit codeword across 16 codewords
- **`WC_PUF_SHA3` build option** - select SHA3-256 instead of SHA-256 for identity hash and HKDF (default: SHA-256)
- **Precomputed GF(2^7) tables** - `const` arrays in `.rodata` (no runtime init, thread-safe, flash-resident on embedded)
- `./configure --enable-puf` (auto-enables HKDF dependency)
- CMake: `WOLFSSL_PUF=yes`
- `WOLFSSL_USER_SETTINGS`: define `WOLFSSL_PUF` and `WOLFSSL_PUF_SRAM`
- See wolfssl-examples/puf for example implementation on STM32 NUCLEO-H563ZI (Cortex-M33, STM32H563ZI)
- Supports test mode (synthetic SRAM)
- Builds to ~13KB `.elf`
- Tested on NUCLEO-H563ZI: enrollment, noisy reconstruction, key derivation all pass
- `.github/workflows/puf.yml`: host build + test workflow for PUF feature
- Doxygen API docs for all 8 public functions
- PUF group added to `doxygen_groups.h`
Implement RFC8773bis (draft-ietf-tls-8773bis-13)
cert_with_extern_psk for TLS 1.3, including protocol checks
and API support.
Includes unit tests for API and handshake behavior as well
as tests in the testsuite using extended examples.
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.
also, minor fixes:
linuxkm/lkcapi_aes_glue.c: in linuxkm_test_aescfb(), call the appropriate aes_cfb_test(), not aes_cfb_test().
linuxkm/lkcapi_glue.c: fix bugprone-macro-parentheses in REGISTER_ALG_OPTIONAL().
linuxkm/module_hooks.c: in updateFipsHash(), add suppression for clang-diagnostic-cast-function-type-strict warnings around actually-safe function pointer casts in call to wc_fips_generate_hash().
* 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[].
Remove the unused AX_CHECK_LIBRARY and REQUIRE_CANONICAL macros from m4/, and stop calling AC_CANONICAL_TARGET from configure.ac since this tree no longer needs target canonicalization.
Update m4/ax_pthread.m4 to the latest AX_PTHREAD macro from the autoconf archive, which brings the host-based canonicalization checks used by the current upstream macro.
* don't default-enable ML-KEM if SHA3/SHAKE are explicitly disabled at user request, or if FIPS <7.
* move ML-KEM flag setup after FIPS setup (like SHA3 and SHAKE flag setup) to allow FIPS overrides.
* remove the unused and misleading "v6-ready" FIPS flavor, and fix v6-dev to get the v6 version triplet.
* Enable ML-KEM by default in build systems (autoconf and CMake)
* Only allow three to-be-standardized hybrid PQ/T combinations by
default
* Use X25519MLKEM768 as the default KeyShare in the ClientHello (if user
does not override that). When Curve25519 is disabled, then either
WOLFSSL_SECP384R1MLKEM1024 or WOLFSSL_SECP256R1MLKEM768 is used as
default depending on the ECC configuration
* Disable standalone ML-KEM in supported groups by default (enable with
--enable-tls-mlkem-standalone)
* Disable extra OQS-based hybrid PQ/T curves by default and gate
behind --enable-experimental (enable with --enable-extra-pqc-hybrids)
* Reorder the SupportedGroups extension to reflect the preferences
* Reorder the preferredGroup array to also reflect the same preferences
* Add async support for ML-KEM hybrids
OCSP Responder Core API:
- Add new public API for creating and managing an OCSP responder
- Add public wrappers for internal OCSP request/response functions
- OcspRespCheck: fix check when authorized responder is loaded into CM
Header Cleanup:
- Remove circular dependency when including `#include <wolfssl/wolfcrypt/asn.h>` from wolfssl/wolfcrypt/ecc.h and wolfssl/wolfcrypt/rsa.h
OCSP Responder Example (examples/ocsp_responder/):
- Add a command-line OCSP responder for interoperability testing with OpenSSL's `openssl ocsp` client
Test Scripts (scripts/):
- ocsp-responder-openssl-interop.test: Tests wolfSSL OCSP responder with `openssl ocsp` client
- ocsp-stapling-with-wolfssl-responder.test: Tests wolfSSL OCSP responder when doing OCSP stapling
Certificate Infrastructure (certs/ocsp/):
- Add DER-format certificates and keys for OCSP testing
- Update renewcerts.sh to generate DER versions
Known Limitations (documented in src/ocsp.c header comment):
- Single request/response per OCSP exchange only
- Key-hash responder ID only (no name-based responder ID)
- No singleExtensions support
ML-DSA: check pointer to the y parameter has not be faulted.
ML-KEM: to harden against faultiong, use a different buffer for private
seed, sigma, and add a check that the buffer was copied correctly.
SHA-3: fix size of check variables.
