* implement wc_local_AesGcmCheckTagSz() with pedantic checks for valid authtag size. SP 800-38D restrictions are now uniformly imposed, unless WC_AES_GCM_ALLOW_NONSTANDARD_TAG_LENGTH is defined (not allow with FIPS).
* refactor tag size checks in wc_AesGcmEncrypt(), wc_AesGcmDecrypt(), wc_AesGcmEncryptFinal(), wc_AesGcmDecryptFinal(), and wc_PKCS7_DecodeAuthEnvelopedData().
* in test.c, update aesgcm_non12iv_test() to skip tag sizes expected to fail.
* add WC_VAES_MIN_BLOCKS, WC_VAES_ECB_MIN_BLOCKS, and WC_VAES_GCM_MIN_BLOCKS, and check against them before using AVX512/VAES implementations.
* in AesCfbDecrypt_C(), enlarge the tmp[] buffer and parameterize its size with newly added WC_AES_CFB_DEC_BUF_BLOCKS.
linuxkm/linuxkm_memory.c: use packed-struct intermediates rather than memcpy()s for wc_get_unaligned() and wc_put_unaligned().
linuxkm/linuxkm_wc_port.h: on old FIPS, retrofit nonnull attribute to GHASH() arg 1, so that it unconditionally writes out the hash.
wolfcrypt/src/aes.c and wolfssl/wolfcrypt/aes.h: in GHASH(), add nonnull attribute to arg 1, and remove runtime nullness check for arg 1 in the implementations.
ARM64/ARM32/Thumb2:
- Inline-asm use param names not registers.
- Return value through first parameter and not first register
- 32-bit values zero extended when loaded off stack
aes.c: Aligned-accedd GHASH for 32-bit CPUs.
test.c: #ifdef protection update.
sha3.h: make digest and block size constants defines for use in hash.h
sha512.h: internal Transform_Sha512* functions declared when only SHA-384.
sp_int.h: include WOLFSSL_SP_MATH_ALL in SP_INT_BITS selection
memory.c: fix printf format to be compatible with more platforms
With WOLFSSL_SMALL_STACK_CACHE, wc_Sha512Free and wc_Sha384Free freed the
cached W buffer as DYNAMIC_TYPE_TMP_BUFFER, but it is allocated as
DYNAMIC_TYPE_DIGEST in InitSha512_Family/InitSha384 and the Copy functions
(the in-Init error cleanup already frees it as DYNAMIC_TYPE_DIGEST).
The mismatch is flagged by the memusage test (DHE_RSA TLS1.2 reports
Errors: 2) and matters for type-bucketed static memory pools. SHA-256/224
already use DYNAMIC_TYPE_DIGEST consistently. Free W as DYNAMIC_TYPE_DIGEST.
use target native int for WC_ATOMIC_INT_ARG, add user overrideability, and
adjust WC_INIT_STATE_COUNT_BITS to depend on sizeof(WC_ATOMIC_UINT_ARG). add
a wc_static_assert to sanity-check WC_INIT_STATE_STATE_BITS, and use CHAR_BIT
opportunistically in the other wc_static_assert to sanity check that CHAR_BIT
is at least 8.
Support AES-XTS AVX512/VAES
Support AES-GCM AVX512/VAES
Support AES-ECB/CBC/CTR AVX512/VAES/AVX1/AES-NI.
Remove code from aes_asm.S/aes_asm.asm
Add CPU defines for AVX512 and VAES
Updated ASM files with new defines for AVX512.
Added support for printing out the new CPU Id flags in benchmark.
Added new files to Windows projects.
aes.c: Supports ECB/CBC/CTR in assembly. Supports calling AVX512/VAES assembly.
* in USE_WINDOWS_API wc_GenerateSeed(), recognize HAVE_AMD_RDSEED, and properly enforce FORCE_FAILURE_RDSEED when CPU support is missing;
* in WOLFSSL_LINUXKM wc_GenerateSeed(), initialize ret to RNG_FAILURE_E, and properly enforce FORCE_FAILURE_RDSEED when CPU support is missing;
* in WOLFSSL_BSDKM wc_GenerateSeed(), properly enforce FORCE_FAILURE_RDSEED when CPU support is missing;
Allow x86 to build with assembly for enable all - disable assembly when x86 and not assembly code available. Add file fe_operations.c when assembly and x86.
x86: fix ECB decrypt to use corect offsets for parameters
fix AES-NI and AVX1 assembly code
fix sp_int with assembly to compile
minor optimizations of AES-GCM
x64: Don't emit move instruction if source and destination are the same reg
Use xor instead of mov 0
minor optimizations of AES-GCM for AES-NI
wolfcrypt/test/test.c: add missing !HAVE_SELFTEST gate around AES-CCM counter overflow test in aesccm_128_badarg_test();
wolfcrypt/src/error.c and wolfssl/wolfcrypt/error-crypt.h: update messages for AES_{GCM,CCM}_OVERFLOW_E.
DecodeExtensionType() guarded the certificatePolicies duplicate check
(VERIFY_AND_SET_OID) under WOLFSSL_SEP only, because the extCertPolicySet
tracking bit was SEP-only. In a WOLFSSL_CERT_EXT-without-WOLFSSL_SEP build a
cert with two certificatePolicies extensions was accepted and the second
silently overwrote the first (RFC 5280 4.2 forbids repeats). Make the bit and
the guard available under WOLFSSL_CERT_EXT too, matching every other
non-repeatable extension.
Add test_DecodeCertExtensions_dup_certpol (DecodeExtensionType now
WOLFSSL_TEST_VIS).
Instead of failing when top bit is set, the standard and current research says to mask it.
WOLFSSL_X25519_NO_MASK_PEER is added to allow the rejection when required.
Use readUnaligned32/64 to ensure no unaligned read faults.
Updated implementations of read/write unaligned 32/64 to not worry about alignment on CPUs that are known to not care.
Regenerate the SP backends so the ECDH secret generators check the caller's
buffer against the number of bytes actually written. Adds a P-384/P-521
buffer-size regression test.
Zeroization:
- Add missing ForceZero on the PRF outputs and WOTS+ chain state that hold
secret key material.
- Route the WOTS sign leaf through a temp so secret chain values never touch
the public signature buffer.
- Add SLHDSA_SHAKE_X4_STATE_W so buffer and wipe sizes stay in sync.
Leak / alloc-failure fixes:
- Fix chain_idx_x4 returning on SAVE_VECTOR_REGISTERS2 failure without freeing
state/fixed (memory leak, and the secret was left unzeroized); break to the
cleanup path instead.
- Guard all function-scope wipes with WC_VAR_OK to avoid a NULL deref when an
allocation fails under WOLFSSL_SMALL_STACK.
Return PUBLIC_KEY_E for wc_ed25519_export_key if public key is not
present.
Return PUBLIC_KEY_E for wc_ed448_export_key if public key is not
present.
Rename several inLen parameters to outLen for consistency.
Fix F-4427
wolfcrypt/src/aes.c: enforce AES-XTS K1!=K2 constraint in wc_AesXtsSetKeyNoInit() unless WC_AES_XTS_ALLOW_DUPLICATE_KEYS and !HAVE_FIPS:
tests/api/test_aes.c: add negative tests to test_wc_AesXtsSetKey() for K1==K2;
wolfcrypt/test/test.c: fix keys in aes_xts_128_inplace_test() and aes_xts_192_inplace_test() so that K1!=K2, update test vectors, and remove associated !HAVE_FIPS gating;
linuxkm/lkcapi_aes_glue.c: synchronize aes_xts_128_test() test of ciphertext stealing in-place with wolfcrypt/test/test.c.
wrapper/rust/wolfssl-wolfcrypt/src/aes.rs: synchronize XTS streaming test with wolfcrypt/test/test.c.
linuxkm/: refactor self-test sensing with version-gated setup in linuxkm_wc_port.h and refactored gates in lkcapi_glue.c.
