NIST standardized the pre-standardization Dilithium signature scheme as
ML-DSA in FIPS 204. Migrate the provider's user-visible surface to
canonical spellings, with a temporary shim that preserves source-level
backward compatibility for existing consumers.
Renames
-------
* File: wolfcrypt/src/dilithium.c -> wolfcrypt/src/wc_mldsa.c
* New canonical header: wolfssl/wolfcrypt/wc_mldsa.h
* Types: dilithium_key -> MlDsaKey, wc_dilithium_params -> MlDsaParams
* Functions: wc_dilithium_* / wc_Dilithium_* -> wc_MlDsaKey_*
* Build gates: HAVE_DILITHIUM -> WOLFSSL_HAVE_MLDSA,
WOLFSSL_DILITHIUM_* / WC_DILITHIUM_* -> WOLFSSL_MLDSA_* / WC_MLDSA_*
* Configure flag: --enable-mldsa (legacy --enable-dilithium still works)
* CMake option: WOLFSSL_MLDSA (legacy WOLFSSL_DILITHIUM emits a
DEPRECATION message)
Backward compatibility
----------------------
wolfssl/wolfcrypt/dilithium.h is now a temporary compatibility shim:
* Forward-translates legacy build gates to canonical (the two sub-gates
read by certs_test.h are translated in settings.h so the auto-generated
header is reachable without including dilithium.h; the remainder lives
in dilithium.h itself).
* Reverse-translates canonical gates back to legacy so unmigrated
consumer code keying off HAVE_DILITHIUM / WOLFSSL_DILITHIUM_* keeps
compiling.
* Provides macro / static-inline aliases for the legacy type and
function names so source-level callers compile unchanged. Sets
WC_DILITHIUMKEY_TYPE_DEFINED to suppress strict-C99 typedef
redefinition in asn_public.h.
Two opt-outs are honored: WOLFSSL_NO_DILITHIUM_LEGACY_GATES disables
build-gate translation; WOLFSSL_NO_DILITHIUM_LEGACY_NAMES disables the
symbol aliases. Both are temporary and the shim will be removed in a
future release. doc/dilithium-to-mldsa-migration.md describes the
migration path for downstream consumers.
ABI note
--------
The library now exports wc_MlDsaKey_* instead of wc_dilithium_*.
Pre-built binaries that linked against the legacy symbols need to
recompile against the shim header (which resolves to the new symbols at
compile time) or migrate to the canonical names directly. Source code
keeps building unchanged.
Other changes
-------------
* wolfssl/wolfcrypt/memory.h: drop ML-DSA sub-gate branching for static
memory pool sizing; WOLFSSL_HAVE_MLDSA builds now pick the larger
LARGEST_MEM_BUCKET / WOLFMEM_BUCKETS / WOLFMEM_DIST unconditionally.
Override these macros for small-mem builds.
* gencertbuf.pl + wolfssl/certs_test.h: outer guards migrated to the
canonical WOLFSSL_HAVE_MLDSA spelling.
* tests/api/test_mldsa.c: adds compile-time API surface validators
(canonical wc_MlDsaKey_* surface plus legacy alias surface) so
signature drift produces a build error during make check.
* IDE files (Xcode, INTIME-RTOS, WIN10, VS2022, CSharp wrapper), Zephyr
CMakeLists.txt, and autotools include.am updated for the rename.
* DYNAMIC_TYPE_DILITHIUM and ML_DSA_PCT_E retained as internal symbols;
scheduled to be renamed alongside the eventual shim removal.
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.
wrapper/CSharp/wolfSSL_CSharp/wolfCrypt.cs: update for new calling conventions around wc_AesNew, wc_curve25519_new, wc_ed25519_new, wc_HashNew, and wc_NewRsaKey, and the corresponding delete functions.
* Adds RNG, ECC(ECIES and ECDHE), RSA, ED25519/Curve25519, AES-GCM, and Hashing to the CSharp wrapper.
* Adds GitHub action for building the CSharp wrapper solution and running wolfCrypt test and a TLS server/client example.
* Adds "new" API's for wolfCrypt for platforms that cannot tolerate the structs directly.
* Fixes for several scan-build warnings.
