This PR adds Doxygen documentation for native wolfSSL API functions that were previously undocumented. It includes documentation notes for APIs gated on specific preprocessor macros:
- WOLF_PRIVATE_KEY_ID: _Id and _Label init helpers (wc_AesInit_Id, wc_AesInit_Label, wc_ecc_init_id, wc_ecc_init_label, wc_InitRsaKey_Id, wc_InitRsaKey_Label) require this for PKCS11 support
- WC_NO_CONSTRUCTORS: New/Delete constructor functions (wc_AesNew/Delete, wc_curve25519_new/delete, wc_ed25519_new/delete, wc_NewRsaKey/DeleteRsaKey) are only available when this is not defined. WC_NO_CONSTRUCTORS is automatically defined when WOLFSSL_NO_MALLOC is defined.
- WOLFSSL_PUBLIC_ASN: ASN functions marked with WOLFSSL_ASN_API include notes indicating they are not public by default
- WOLFSSL_DUAL_ALG_CERTS: wc_GeneratePreTBS and wc_MakeSigWithBitStr for Post-Quantum dual algorithm certificate signing
The New/Delete functions are documented as being exposed to support allocation of structures using dynamic memory to provide better ABI compatibility.
In defense against attack, assume the imported public key is not trusted
and check it matches the private key if set.
Added APIs that allow application to explicitly trust public key.
Original APIs default to not trusting public key.
* Added PK callback context tests for client/server examples (`SetupPkCallbackContexts`).
* Added new test define for `TEST_PK_PRIVKEY` to allows simulating hardware based private key.
* Added new test.h function for loading PEM key file and converting to DER (`load_key_file`).
* Added way to get private key signature size (`GetPrivateKeySigSize`).
* Added new ECC API `wc_ecc_sig_size_calc` to return max signature size for a key size.
* Added inline comments to help track down handshake message types.
* Cleanup of RSS PSS terminating byte (0xbc) to use enum value.
* Fixed bug with PK callback for `myEccVerify` public key format.
* Fixed bug with PK callback for ED25519 verify key buffer in DoServerKeyExchange.
