1.5.2.1 DRV_CRYPTO_HASH_Digest()
HASH_ERROR DRV_CRYPTO_HASH_Digest (void * contextData, HASHCON_MODE mode, const uint8_t * data, uint32_t dataLength, const uint8_t * digest, uint32_t digestLength)
This function performs a complete hash operation and generates a digest.
| contextData |
A pointer to the context block that contains the hash context data. |
| mode |
The HASHCON_MODE to use. |
| data |
The data to add to the operation. |
| dataLength |
The length of the data. |
| digest |
Buffer to contain the digest. |
| digestLength |
The size of the digest buffer. |
| HASH_NO_ERROR |
Success. |
| HASH_CONTEXT_ERROR |
Invalid or corrupted hash context. |
| HASH_INITIALIZE_ERROR |
Failure during hash initialization. |
| HASH_STATE_ERROR |
Invalid or unexpected hash state. |
| HASH_EXECUTE_ERROR |
Failure during hash execution. |
Note:
A hash operation must be in progress (initialized by DRV_HASH_CRYPTO_Initialize()).
