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
Enable with: CPPFLAGS="-DWOLF_CRYPTO_CB_AES_SETKEY -DWOLF_CRYPTO_CB_FREE"

Mostly combinations of NO_WOLFSSL_CLIENT, NO_WOLFSSL_SERVER and
WOLFSSL_NO_CLIENT_AUTH were failing.
Added configurations to CI loop.
wc_AesGcmDecryptFinal: use WC_AES_BLOCK_SIZE to satisfy compiler.
* More PQC configurations
* More CMake setups
* Fix various bugs uncovered by these tests
Added some missing feature additions to CMake to make the example
`user_settings_all.` config file work for the CI test.
Update ret code to match docs and update docs
Replace magic numbers with appropriate define
Define MAX_ENTROPY_BITS when MEMUSE not enabled
Fix type cast windows detection
Older FIPS modules still need the old check
CodeSpell you're wrong, that is what I want to name my variable
Turn the hostap into a manual dispatch until it gets fixed
Upon closer review we can not skip the test when memuse enabled
Fix whitespace stuff found by multitest
More syntax things
Correct comments based on latest findings
wolfssl/wolfcrypt/settings.h: if DEBUG_WOLFSSL && !WC_NO_VERBOSE_RNG, set WC_VERBOSE_RNG, and add WOLFSSL_NO_DEBUG_CERTS to allow inhibition of WOLFSSL_DEBUG_CERTS.
