Modes (CTR, GCM, CCM, etc.) can be supported either directly or fallback
to invoking the crypto callback with a "direct" (ECB) mode.
Software implementation and AES tables are stripped under CB_ONLY_AES.
wc_swdev gains AES support so WOLF_CRYPTO_CB_ONLY_AES builds can be
tested.
crypto find cb support added to wc_AesSetKey in order to support current
CI tests that use INVALID_DEVID.
Add WOLF_CRYPTO_CB_ONLY_SHA256: when set, the SHA-256 software.
wc_Sha256FinalRaw is reduced to a stub returning NO_VALID_DEVID, and
sha256.h force-defines WOLFSSL_NO_HASH_RAW so the constant-time TLS HMAC
path falls back to its backend-opaque variant.
Incompatible with
WOLFSSL_SHA224, which aliases the SHA-256 statics; #error guard added.
Add wc_swdev support for SHA-256 for testing.
utilities for generic SetKey and ExportKey operations on HMAC, RSA, ECC,
and AES. Add wc_ecc_size/wc_ecc_sig_size callback hooks for hardware-only
keys. Integrate into configure.ac as --enable-cryptocbutils=setkey,export
options with CI test configurations in os-check.yml.
Add test handlers in test.c and api.c with export/import delegation
pattern, small-stack-safe allocations, custom curve support, and
DEBUG_CRYPTOCB helpers.
Offload ML-DSA operations onto a PKCS#11 token via the cryptoCb
interface:
* Key generation
* Signature generation
* Signature verification
* Key import
Both the pure and pre-hash versions are supported. Not yet supported are
the pre-hash versions that also offload the hashing onto the token.
This also fixes casting errors introduced in #9780 due to usage of
uintptr_t, which is unavailable without including stdint.h on some
platforms. Use the wolfssl own wc_ptr_t instead.
Add CryptoCB-based AES key import support to enable Secure Element
offload without exposing raw AES key material to wolfCrypt.
When WOLF_CRYPTO_CB_AES_SETKEY is defined, wolfCrypt invokes a CryptoCB
callback during AES key setup. Behavior is determined by the callback
return value:
- If callback returns 0: Key is imported to the device (aes->devCtx).
Key is NOT copied to wolfCrypt RAM; GCM H/M tables are NOT generated.
Full hardware offload is assumed.
- If callback returns CRYPTOCB_UNAVAILABLE: Device does not support
SetKey. Normal software path is used; key is copied to devKey for
optional encrypt/decrypt acceleration.
- Any other error: Propagated to the caller.
Key points:
- Add wc_CryptoCb_AesSetKey() callback for AES key import
- Update AES SetKey paths to call CryptoCB and branch on return value
- Skip GCM H/M table generation when callback succeeded (devCtx set)
- Preserve existing behavior when devId is INVALID_DEVID or
WOLF_CRYPTO_CB_AES_SETKEY is not defined
Testing:
- Add unit test for CryptoCB AES SetKey (verifies key isolation when
callback succeeds)
- Add end-to-end AES-GCM offload test (SetKey, Encrypt, Decrypt, Free
via CryptoCB)
- Tests use a mock SE with software AES to validate routing

If the cryptocb provider supports specific SHA512/224 and SHA512/256
hashtype, this commit allows to:
1. avoid a copy
2. do not touch the output buffer outside of the cryptocb handler
2 might be important for cryptocb provider that needs special handling
of memory buffer (DMA, memory mapping).
which force on BUILDING_WOLFSSL and do boilerplate includes, and update library
sources to include them at the top.
wolfssl_sources.h includes types.h, error-crypt.h, and logging.h, and
conditionally, config.h. settings.h and wc_port.h are unconditionally
included at the top of types.h.
wolfssl_sources_asm.h includes settings.h, and conditionally, config.h.
Add wolfssl_sources*.h to wolfcrypt/src/include.am, and to several IDE/ project
files.
Also added a TEST_WOLFSSL_SOURCES_INCLUSION_SEQUENCE clause in
wolfssl/wolfcrypt/settings.h to allow coverage testing.
In wolfcrypt/src/misc.c, retain existing ad hoc boilerplate includes, and use
them if WOLFSSL_VIS_FOR_TESTS, otherwise include the new wolfssl_sources.h.
Define WOLFSSL_VIS_FOR_TESTS at top of wolfcrypt/test/test.c.
Also renamed WOLFSSL_NEED_LINUX_CURRENT to WOLFSSL_LINUXKM_NEED_LINUX_CURRENT,
for clarity.
