1.4.2.5 DRV_CRYPTO_ECDSA_Sign_Start()
CRYPTO_PKE_RESULT DRV_CRYPTO_ECDSA_Sign_Start (uint8_t * inputHash, uint32_t hashLength, uint8_t * privateKey, uint32_t privateKeyLength, PKE_ECC_CURVE eccCurve)
Initialize and start the non-blocking ECDSA signature generation process.
| inputHash |
Hash input to use for the signature generation. |
| hashLength |
Length of the hash input. |
| privateKey |
Public key input for signature generation. |
| privateKeyLength |
Length of the public key. |
| eccCurve |
ECC curve used for generation. |
CRYPTO_PKE_RESULT_SUCCESS on success. CRYPTO_PKE_RESULT_ERROR_FAIL on failure. |
Note:
This function initializes the hardware crypto engine with ECDSA parameters.
