.github/workflows/wolfCrypt-Wconversion.yml: Add -Wcast-qual to all scenarios.
wolfssl/wolfcrypt/signature.h, wolfcrypt/src/signature.c, doc/dox_comments/header_files/signature.h:
Remove incorrect const qualifier on the key argument in
* wc_SignatureVerifyHash()
* wc_SignatureVerify()
* wc_SignatureGenerateHash()
* wc_SignatureGenerateHash_ex()
* wc_SignatureGenerate()
* wc_SignatureGenerate_ex()
This fixes UB code patterns throughout signature.c. key is inherently
accessed readwrite by the underlying low level crypto. Fortunately, wolfCrypt
has no APIs/methods to allow actual const MPI key objects, therefore these
seeming breaking API changes can't actually break any users.
globally:
* Add const qualifiers to all struct pointer members that are assigned values
computed from const pointers.
* Add const qualifiers to intermediate casts for accessors and read-only
dereference constructs, as needed for -Wcast-qual hygiene, e.g. for a macro
GET_U16(a), use (*(const word16*)(a)) rather than (*(word16*)(a)).
* Add const qualifiers to internal declarations, and remove illegal casts, as
needed for -Wcast-qual hygiene.
* Add missing const qualifiers to all casts for argument, operand, and
assignment type agreement, as needed for -Wcast-qual hygiene, e.g.
"*data = (const byte*)dataASN->data.ref.data" rather than
"*data = (byte*)dataASN->data.ref.data".
wolfssl/wolfcrypt/asn.h, wolfssl/wolfcrypt/asn_public.h, wolfcrypt/src/asn.c, wolfcrypt/src/asn_orig.c:
* Add additional lifecycle management for object members that are only sometimes locally allocated:
DNS_entry.nameStored
DNS_entry.ipStringStored
DNS_entry.ridStringStored
wolfssl/wolfcrypt/types.h: add WC_BARRIER() macro -- a portable construct that
prevents compiler optimizers from reordering operations across the barrier.
wolfssl/wolfcrypt/blake2-impl.h, wolfcrypt/src/blake2s.c, wolfcrypt/src/blake2b.c:
* In blake2b_init(), blake2b_init_key(), blake2s_init(), and
blake2s_init_key(), refactor blake2b_param initialization using WC_BARRIER()
(fixes volatile abuse that triggered -Wcast-qual).
* Remove the residual and unused WOLFSSL_BLAKE2[BS]_INIT_EACH_FIELD code.
wolfcrypt/src/ecc.c and wolfssl/wolfcrypt/ecc.h:
Remove incorrect const qualifier on curve arg to wc_ecc_free_curve() (internal function).
- 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.
* 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
The WOLFSSL_OLDTLS_SHA2_CIPHERSUITES else-branch for
BUILD_TLS_PSK_WITH_AES_128_CBC_SHA256 referenced undeclared variable
`tls1` instead of `tls`, a copy-paste typo from commit a975ba9e97
(2019). This caused a compilation error when both WOLFSSL_STATIC_PSK
and WOLFSSL_OLDTLS_SHA2_CIPHERSUITES were defined.
Add PSK CI config with WOLFSSL_OLDTLS_SHA2_CIPHERSUITES to prevent
regressions.

- Add a GitHub Actions workflow to automate testing of Python integration
- Implement Blake2b and Blake2s hash functions into the EVP API.
- Improve OpenSSL compatibility by standardizing ASN.1 encoding for
serial numbers and registered IDs, streamlining cipher stack management, and optimizing stack node copying.
- Enforce maximum fragment size during data transmission to ensure proper TLS/DTLS record fragmentation.
