Replace the liboqs-based pre-standardization SPHINCS+ implementation
with the native FIPS 205 SLH-DSA implementation across the
certificate / ASN.1 / X.509 layers, and add SLH-DSA-rooted test
certificates plus TLS 1.3 .conf scenarios that exercise the new
verification path. All liboqs SPHINCS+ code is removed.
This enables SLH-DSA for certificate chain authentication: CA
certificates signed with SLH-DSA, certificate signature verification
against an SLH-DSA root. TLS 1.3 entity authentication via
CertificateVerify with SLH-DSA will be added in a follow-up PR.
Follows RFC 9909 (X.509 Algorithm Identifiers for SLH-DSA) and
NIST FIPS 205. Supports both SHAKE and SHA-2 parameter families
across all twelve standardized variants.
DER codec:
- New PrivateKeyDecode, PublicKeyDecode, KeyToDer, PrivateKeyToDer,
PublicKeyToDer with RFC 9909 encoding (bare OCTET STRING containing
4*n raw bytes = SK.seed || SK.prf || PK.seed || PK.root, no nested
wrapper). OID auto-detection across all twelve SHAKE / SHA-2 variants.
- PublicKeyDecode raw-bytes fast path mirrors wc_Falcon_PublicKeyDecode
and wc_Dilithium_PublicKeyDecode so callers (notably
wolfssl_x509_make_der and ConfirmSignature, which pass the raw
BIT STRING contents stashed by StoreKey) decode correctly. Honours
the caller's *inOutIdx start offset.
- Error paths in Private/PublicKeyDecode preserve params/flags/
inOutIdx and only ForceZero the buffer half each helper actually
writes; skip the wipe entirely on BAD_LENGTH_E (no bytes touched).
- ImportPublic uses |= on flags so a Private-then-Public import
sequence retains FLAG_PRIVATE.
OID dispatch:
- 12 standardized NIST OIDs (6 SHAKE + 6 SHA-2) per RFC 9909. The
pre-standardization OID-collision mechanism is removed since NIST
OIDs do not collide.
- wc_SlhDsaOidToParam / wc_SlhDsaOidToCertType return NOT_COMPILED_IN
(rather than -1) for recognised SLH-DSA OIDs whose parameter set
isn't built; wc_IsSlhDsaOid recognises both. The x509 dispatch
surfaces this as a precise diagnostic instead of the generic
"No public key found".
- wc_GetKeyOID picks a placeholder parameter from whatever variant is
compiled in and #errors at compile time if none is.
- asn_orig.c EncodeCert / EncodeCertReq accept SHA-2 SLH-DSA keyTypes
alongside SHAKE.
Tests and fixtures:
- Test cert chain in certs/slhdsa/: SLH-DSA-SHAKE-128s and
SLH-DSA-SHA2-128s self-signed roots that sign reused ML-DSA-44
entity keys (server + client), plus the gen script
(gen-slhdsa-mldsa-certs.sh, OpenSSL >= 3.5).
- New TLS 1.3 .conf scenarios under tests/suites.c dispatch:
test-tls13-slhdsa-shake.conf, test-tls13-slhdsa-sha2.conf, and a
wrong-CA negative test test-tls13-slhdsa-fail.conf.
- DER round-trip and on-disk decode tests; bench_slhdsa_*_key.der
fixtures regenerated with wolfSSL's own encoder so the codec is
pinned to RFC 9909.
- New unit test test_wc_slhdsa_x509_i2d_roundtrip exercises the raw
PublicKeyDecode entry point that wolfssl_x509_make_der relies on.
- test_wc_slhdsa_check_key now tests both Public-then-Private and
Private-then-Public import orderings.
Build / ABI:
- DYNAMIC_TYPE_SPHINCS = 98 kept as RESERVED with a tombstone comment
for ABI stability; new code should use DYNAMIC_TYPE_SLHDSA (107).
- All build system / IDE project files updated; SPHINCS+ sources,
headers, and test data removed.
- Dead bench_slhdsa_*_key arrays removed from gencertbuf.pl and
certs_test.h; the .der files on disk drive the decode tests.
Follow-up to #7731 ("Changes needed for default TLS support in zephyr
kernel"). Zephyr 4.3's TLS socket integration uses three additional
wolfSSL features that were not needed by the 3.7 integration, plus an
extension to the native_sim time-source gates introduced in #7731.
native_sim timer gates (src/internal.c, wolfcrypt/src/wc_port.c):
Extend the !CONFIG_BOARD_NATIVE_POSIX gate in LowResTimer() and the
CONFIG_BOARD_NATIVE_POSIX RTC path in z_time() to also cover
CONFIG_BOARD_NATIVE_SIM. Zephyr 4.3 renamed the simulator board from
native_posix to native_sim; without this, k_cpu_idle() on native_sim
advances simulated time during DTLS retransmit loops and the RTC path
falls through to uptime-since-boot. Behavior on native_posix is
unchanged.
New Kconfig options (zephyr/Kconfig, zephyr/user_settings.h):
CONFIG_WOLFSSL_SESSION_EXPORT -> HAVE_EXT_CACHE
Required by consumers that serialize TLS session state across
connections via wolfSSL_i2d_SSL_SESSION / wolfSSL_d2i_SSL_SESSION.
CONFIG_WOLFSSL_KEEP_PEER_CERT -> KEEP_PEER_CERT
Retain the peer certificate after handshake so the application
layer can inspect it via wolfSSL_get_peer_certificate.
CONFIG_WOLFSSL_ALWAYS_VERIFY_CB -> WOLFSSL_ALWAYS_VERIFY_CB
Invoke an application-set verify callback on successful chain
validation in addition to validation failures.
All three are default-off; customers opt in the same way they do for
the existing CONFIG_WOLFSSL_DTLS / ALPN / PSK feature options.
.wolfssl_known_macro_extras: register HAVE_EXT_CACHE.
* 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
* Store in extensions the full octet string
Store in WOLFSSL_X509_EXTENSION.value always the full contents of the
OCTET STRING of the extension, instead of different type of data
depending on the type of extension. Previously this was only done for
unknown extensions.
* Avoid local variables in 'DecodeExtKeyUsageInternal'
There is a great performance loss on configs using 'WOLFSSL_NO_MALLOC',
'WOLFSSL_STATIC_MEMORY' and 'USE_FAST_MATH' if function
'DecodeExtKeyUsageInternal' uses intermediate variables. This can be
observed running the Zephyr test 'wolfssl_test/prj-no-malloc.conf'.
Avoid using intermediate variables, and use raw pointers to the final
destination instead.
* Add missing calls to 'FreeDecodedCert'
* Return error code from 'wolfSSL_ASN1_STRING_into_old_ext_fmt'
* Fix lines larger than 80
* Allow NULL parameters for 'DecodeAuthKeyId'
* Add comment explaining build option '--enable-old-extdata-fmt'
* Test full OCTET STRING in tests/api.c
* wolfSSL_X509V3_EXT_d2i: Honor 'WOLFSSL_SMALL_STACK'
* zephyr/wolfssl_test_no_malloc: Increase test timeout
* wolfSSL_X509V3_EXT_d2i: Extract repeated code into common part
* wolfcrypt: Remove 'WOLFSSL_LOCAL' from .c files
* wolfcrypt: Change location of functions to make diff easier
* Add support for CMake
* Add support for Zephyr
* Make sure the internal key state is properly handled in case a public
key is imported into a reloaded private key.

* Make sure wc_kyber implementation is compiled using CMake (also for
Zephyr)
* Fix compilation issue when Liboqs is also enabled
