Allow a quantum-safe-only TLS 1.3 stack - ML-KEM key exchange with ML-DSA or
SLH-DSA authentication - with RSA, ECC and DH all disabled (the CNSA 2.0 /
EO 14412 posture).
- Treat a usable standalone ML-KEM group as a valid key exchange and
Falcon/ML-DSA/SLH-DSA as valid authentication, so the "no cipher suites"
#errors no longer fire (ssl.c, internal.h), and extend the CopyDecodedToX509
pkCurveOID guard to match the struct member guards (internal.c).
- asn.c: guard the RSA/ECC-only certificate signing helpers so cert generation
compiles with RSA and ECC disabled, while keeping MakeSignatureCb available
for the WOLFSSL_CERT_SIGN_CB (TPM/HSM) offload path.
- tls.c: advertise the psk_dhe_ke exchange mode when a standalone ML-KEM group
is usable on the client side, that is when the build has both key generation
and decapsulation. Without it an ML-KEM-only build fell back to psk_ke, the
resumption key schedules diverged, and the first AEAD record failed to
authenticate (AES_GCM_AUTH_E), breaking session-ticket resumption.
- tls13.c: hoist the hashAlgo void cast in EncodeSigAlg out of the Ed25519 and
Ed448 cases so a build with no classic signature algorithm still marks the
parameter used.
- Examples and tests: add ML-DSA and SLH-DSA certificate selection (gated on
NO_RSA so it only applies in true PQC-only builds) and default to TLS 1.3
when no classic auth is built in and a post-quantum signature is available
(test.h, client/server/echo*, test_tls13.c). SLH-DSA uses the SHAKE-128s leaf
certificates and their shared 128s root.
- CI: add PQC-only entries to the pq-all.json config list (ML-DSA and SLH-DSA),
each exercising the build, a full TLS 1.3 handshake, and ML-KEM-only
session-ticket resumption.
Whether a build can authenticate with a post-quantum certificate is three
separate questions - is the algorithm compiled in, are test credentials wired
up for the enabled parameter set, and can this build sign - so test.h answers
them with three tiers of macro rather than testing WOLFSSL_HAVE_MLDSA and
WOLFSSL_HAVE_SLHDSA directly:
- TEST_HAVE_MLDSA_CERT_FILES / TEST_HAVE_SLHDSA_CERT_FILES: the credential
paths name real files. ML-DSA needs an enabled parameter level; SLH-DSA needs
a 128s parameter set, since both families share a 128s root and only those
certificates are wired up, and PEM decoding, since the entity certificates
ship as PEM only. Loading a certificate needs verification support alone, so
test_tls13.c uses this tier - it only needs a certificate on the context.
- TEST_HAVE_MLDSA_CERTS / TEST_HAVE_SLHDSA_CERTS: the above, plus the ability
to sign. A verify-only build derives WOLFSSL_MLDSA_NO_SIGN and drops private
key support entirely, so it can neither load the key nor produce a
CertificateVerify. The example credential ladders use this tier.
- TEST_HAVE_PQC_CERT_AUTH: either of those, plus WOLFSSL_TLS13. Both algorithms
are TLS 1.3 only, so folding the version into the macro keeps the version
defaults and the PSK fallbacks in the client, server and echo examples from
disagreeing. Falcon is deliberately absent, having no credentials in the
ladders, so a Falcon-only build keeps the historic TLS 1.2 PSK behavior.
A build that fails a gate now falls back to PSK instead of naming credentials
it cannot use, which removes two hard #errors that were reachable from
configure: --enable-slhdsa with only non-128s parameter sets broke every build
that includes test.h, even ones with RSA and ECC enabled that would never touch
an SLH-DSA credential.
Also in the credential material and the configurations this opens up:
- test.h: pair the DER ML-DSA certificate with mldsa<N>-key.der. The
mldsa<N>_priv-only.der files are standalone PKCS#8 encoding vectors from an
unrelated key pair, so a build without PEM decoding presented a certificate
and signed with a key that did not match it, and the peer rejected the
CertificateVerify.
- echoserver.c: load the SLH-DSA key with CERT_FILETYPE like every neighboring
branch, rather than hardcoding WOLFSSL_FILETYPE_PEM against a certificate
loaded in the build-dependent format.
- internal.c, tls13.c, ssl_load.c: mark ssl, sigOut, keyType and keySz used.
Every reader of these sits in a per-algorithm block, so a build with no
signing algorithm at all left them unused and -Werror rejected the library.
- tests/api.c: skip test_wolfSSL_PKCS8 unless RSA, ECC or PEM decoding is
available. With none of them every key-loading body compiles out, leaving the
file locals unused and nothing for the test to do.
Make every --enable-tinytls13 spelling build and pass locally, and grow the
CI matrix to cover them. These are fixes found while testing the configs the
CI workflow had not actually exercised.
- internal.h, internal.c, ssl_load.c: include ML-DSA and Falcon in the
pkCurveOID member and producer guards so the PSK plus ML-DSA build compiles.
- tls13.c: gate the DoTls13CertificateVerify definition on NO_CERTS to match
its call site.
- settings.h: let the AES-256 adder survive the floor, default the
user_settings path to the SHA-256 floor, make WOLFSSL_NO_MALLOC opt-in so
the test suite still runs, and keep ML-DSA ASN.1 for the cert profile.
- configure.ac: drive ENABLED_ASM and emit WOLFSSL_NO_ASM for the small C
floor, restrict SP math to P-256, strip ML-DSA ASN.1 only on the PSK floor,
and print a notice for the reduced security cert verify.
- examples: guard the cert loading paths for NO_CERTS and treat NO_CERTS as
PSK mode in echoserver and echoclient.
- Add examples/configs/tinytls13_smoke.c, an in memory TLS 1.3 handshake test
that drives PSK, ECDSA, ML-DSA-65 and RSA-PSS chain verify, plus forced
cipher suites, for builds with no example or unit test harness.
- certs: add ECDSA leaves signed by the ML-DSA-65 and RSA-PSS CAs so the cert
profiles drive a real PQC and PSS chain verify in CI.
- .github/workflows/tinytls13.yml: cover every profile and adder, run the
smoke handshake on the build verified configs, and least privilege the
workflow token.
configure.ac:
* add --enable-all-osp to separate OSP meta-feature sets from --enable-all, allowing --enable-all --disable-all-osp --disable-opensslall (e.g. for testing OPENSSL_COEXIST).
* fix enable_all_crypto=yes in enable-all to be conditional on "$enable_all_crypto" = "".
* move enable_rsapss=yes from enable-all to enable-all-crypto.
examples/ and testsuite/: #undef OPENSSL_COEXIST unconditionally rather than only if defined(OPENSSL_EXTRA), to capture -DOPENSSL_EXTRA_X509_SMALL or any other such variants.
No functional changes.
Several compat symbols that were formerly enums are now macros.
All library source is refactored to use only native symbols in all code gated in with --enable-all-crypto --enable-opensslextra.
wolfcrypt/test/test.c is similarly refactored to use only native symbols.
examples/ and tests/ are unmodified except for header setup to disable OPENSSL_COEXIST and TEST_OPENSSL_COEXIST.
tests/api.c: add error_test() adapted from wolfcrypt/test/test.c, checking all error strings for expected presence/absence and length, called from existing test_wolfSSL_ERR_strings().
wolfssl/ssl.h, wolfssl/error-ssl.h, and wolfssl/wolfcrypt/error-crypt.h:
* move several negative error return codes from ssl.h to error-ssl.h,
* renumber them to conform to existing sequence, and
* include error-ssl.h from ssl.h;
* add special-case WOLFSSL_DEBUG_TRACE_ERROR_CODES macros for WOLFSSL_FAILURE;
* add missing WOLFSSL_API attribute to wc_backtrace_render().
add numerous WC_NO_ERR_TRACE()s to operand error code uses, cleaning up error traces in general, and particularly when WOLFSSL_DEBUG_TRACE_ERROR_CODES_ALWAYS.
* crypto lib (36),
* crypto test&benchmark (20),
* TLS lib (179),
* examples (122),
* linuxkm (3),
* tests/api.c (2272).
Fix checking of negative with unsigned variables.
Check digestSz for 0 in wc_SSH_KDF() so that no possibility of dividing
by zero.
Change XMEMCPY to XMEMSET in renesas_sce_util.c.
Fix test.c to free prvTmp and pubTmp on read error.
Remove unused variables.
XFREE checks for NULL so don't check before call.
Move variable declarations to reduce scope.
add wolfCrypt error codes IO_FAILED_E "Input/output failure" and SYSLIB_FAILED_E "System/library call failed";
tests/api.c and tests/unit.c: flush stdout for error message in Fail() macro, add fflush(stdout) after printf()s, print success message at end of unit_test(), and send several error messages to stderr instead of stdout;
wolfcrypt/test/test.c: add fallthrough macro definition of printf() that pairs it with fflush(stdout);
unit.h: in definition of macro AssertPtr(), add PRAGMA_GCC("GCC diagnostic ignored \"-Wpedantic\"");
sp_int.c: refactor several lingering instances of "if (0) { ... }" code pattern to #if 0 ... #endif.
Currently, wolfssl.vcxproj and IDE/WIN10/wolfssl-fips.vcxproj do not use the
same scheme for their output and intermediate directories. Further, across
configuration/platform combinations, wolfssl.vcxproj isn't consistent, either.
For example:
```
Release|x64
OutDir: $(SolutionDir)$(Platform)\$(Configuration)\
IntDir: $(Platform)\$(Configuration)\obj\
Release|Win32
OutDir: $(SolutionDir)$(Configuration)\
IntDir: $(Configuration)\obj\
```
This commit makes every configuration/platform combo for all Visual Studio
projects follow the same pattern:
```
OutDir: $(SolutionDir)$(Platform)\$(Configuration)\
IntDir: $(Configuration)\$(Platform)\$(ProjectName)_obj\
```
The `$(ProjectName)_obj` piece gets rid of a Visual Studio warning about not
mingling the intermediate objects of disparate builds.
