Add support for compiling ASM for Thumb2
Add Curve25519 ASM for Thumb2
Limit assembly code compiled when Ed25519 not required.
Rework all assembly implementations to replace ge_*() functions instead
of having fe_ge_*() versions that take many parameters.
Get ARM32 inline asm working.
tweak several #includes of settings.h to include types.h instead (all of these are for clarity, as types.h is indirectly included by later #includes), and add #include <wolfssl/wolfcrypt/types.h> where missing;
remove trailing semicolons from PRAGMA*() macro invocations as they are unneeded and can be harmful (inducing frivolous -Wdeclaration-after-statement etc.).
Add support for:
- SM2 elliptic curve and SM2 sign/verify
- SM3 digest
- SM4 cipher with modes ECB/CBC/CTR/GCM/CCM
Add APIs for SM3 and SM4.
Add SM2 sign and verify APIs.
Add support for SM3 in wc_Hash and wc_Hmac API.
Add support for SM3 and SM4 through EVP layer.
Add support for SM2-SM3 certificates. Support key ID and name hash being
with SHA-1/256 or SM3.
Add support for TLS 1.3 cipher suites: TLS-SM4-GCM-SM3, TLS-SM4-CCM-SM3
Add support for TLS 1.2 SM cipher suite: ECDHE-ECDSA-SM4-CBC-SM3
Add support for SM3 in wc_PRF_TLS.
Add SM2-SM3 certificates and keys. Generated with GmSSL-3.0.0 and
OpenSSL.
wolfssl/wolfcrypt/types.h: add 'U' suffix to W64LIT() macro defs, and add SW64LIT() macro defs (not yet used anywhere);
wolfcrypt/src/asn.c: add !WOLFSSL_ECC_CURVE_STATIC gate around DataToHexStringAlloc() to resolve -Wunused;
wolfcrypt/src/ecc.c: guard against zero-valued "len" arg to wc_ecc_get_curve_id_from_oid();
wolfcrypt/src/wc_port.c: fix several argument implicit sign changes in USE_WINDOWS_API paths;
wolfssl/wolfcrypt/ecc.h: remove const attribute from inline buffers in WOLFSSL_ECC_CURVE_STATIC struct ecc_set_type.
wolfssl_sce_unit_test.c:
sce_crypt_Sha_AesCbcGcm_multitest(): duplicate condition
ssl_asn1.c:
wolfSSL_i2t_ASN1_OBJECT(): done is not needed
MonthStr(): fix bounds check on i
woolfcrypt_test.c, test_main.c, wolfssl_tsip_unit_test.c, devices.c,
aes.c, des3.c:
Variable not used.
asn.c:
DecodeSubjKeyId(): sz is unsigned - check for less than zero does
nothing
kcapi_rsa.c:
KcapiRsa_Decrypt(): fix ret check by using else
KcapiRsa_Encrypt(): make same change for consistency
kcapi_hash.c:
KcapiHashFinal(): move ret into #ifdef where it is needed
stm32.c:
wc_Stm32_Hash_GetDigest(): i redeclared with different type - use ii
instead
bio.c, conf.c:
XFREE checks for NULL
Reduce scope of varialbes.
Condition same.
AES C impl: don't align to 32 bytes, align to 16 as buffer is 16 bytes
long.
SP int: Don't call _sp_mulmod but call sp_mul and _sp_div to do mod
operation. For RSA, fewer calls for mod operation means less stack used
at deepest point.
fix for benign clang-analyzer-deadcode.DeadStores in aes.c:wc_AesFeedbackEncrypt();
fix for cppcheck:selfAssignment in chacha.c:wc_Chacha_wordtobyte().
Tested with `./configure --disable-asm --enable-32bit --enable-asn=original --enable-cryptonly CFLAGS="-Wconversion -pedantic" && make`. Some progress with ASN template, but not complete.
ForceZero the client and server secret regardless of whether TLS 1.3 as
it may change but have been copied in.
ForceZero the input buffer in wolfSSL_Clear() when encryption was on.
Changed wc_PRF_TLS to only check the parts of data used.
Changed where scatch is added for checking in wc_AesCtrEncrypt.
Change wc_MakeRsaKey to memset p, q, tmp1, tmp2 and tmp3 to all zeros so
that MemZero check works. Memset not needed otherwise.
Changes for new compiler - thinks uninitialized.
AES-GCM stremaing was caching IV even when larger than buffer copying
into.
Instead, require calls to wc_AesGcmSetIV() or wc_AesGcmSetExtIV() to
cache IV.
wc_AesGcmInit() now uses passed in IV or retrieves from cache.
fix file descriptor leaks in AF_ALG code, and fix return codes (WC_AFALG_SOCK_E, not -1) in afalg_aes.c;
fixes for sanitizer-detected forbidden null pointer args in AfalgHashUpdate() and AfalgHashCopy();
fixes for resource leaks in api.c test_wolfSSL_AES_cbc_encrypt() (missing wc_AesFree()s);
fixes for resource leaks in test.c openssl_test() (missing wolfSSL_EVP_CIPHER_CTX_cleanup());
also some local fixes for bugprone-signed-char-misuse, readability-redundant-preprocessor, and clang-diagnostic-strict-prototypes, in src/pk.c and src/ssl.c.
