Enumeration Type Documentation

HASH_result_status

enum HASH_result_status

HASH function status return.

Enumerator
HASH_ERR_OK	No errors, good status.
HASH_ERR_NOT_INIT	Error, HASH driver not initialized.
HASH_ERR_ALREADY_INIT	Error, HASH driver already initialized.
HASH_ERR_DEV_BAD_STATE	Error, HASH bad state.
HASH_ERR_INVALID_PARA	Error, invalid HASH parameter.

hash_type

enum hash_type

HASH function type.

Enumerator
HASH_TYPE_MD5	HASH type MD-5.
HASH_TYPE_SHA1	HASH type SHA-1.
HASH_TYPE_SHA256	HASH type SHA-256.

Function Documentation

hal_hash_close()

int hal_hash_close

(

void

)
