Generation and authentication of Message Digests (aka hashes) must be done in parts using the following sequence:
psa_drv_hash_setup_tpsa_drv_hash_update_tpsa_drv_hash_update_tpsa_drv_hash_finish_tIf a previously started Message Digest operation needs to be terminated before the psa_drv_hash_finish_t operation is complete, it should be aborted by the psa_drv_hash_abort_t. Failure to do so may result in allocated resources not being freed or in other undefined behavior.
| typedef struct psa_drv_hash_context_s psa_drv_hash_context_t |
The hardware-specific hash context structure.
The contents of this structure are implementation dependent and are therefore not described here
Definition at line 64 of file crypto_accel_driver.h.
| typedef psa_status_t(* psa_drv_hash_setup_t) (psa_drv_hash_context_t *p_context) |
The function prototype for the start operation of a hash (message digest) operation.
Functions that implement this prototype should be named in the following convention:
Where ALGO is the name of the underlying hash function
| [in,out] | p_context | A structure that will contain the hardware-specific hash context |
| PSA_SUCCESS | Success. |
Definition at line 81 of file crypto_accel_driver.h.
| typedef psa_status_t(* psa_drv_hash_update_t) (psa_drv_hash_context_t *p_context, const uint8_t *p_input, size_t input_length) |
The function prototype for the update operation of a hash (message digest) operation.
Functions that implement this prototype should be named in the following convention:
Where ALGO is the name of the underlying algorithm
| [in,out] | p_context | A hardware-specific structure for the previously-established hash operation to be continued |
| [in] | p_input | A buffer containing the message to be appended to the hash operation |
| [in] | input_length | The size in bytes of the input message buffer |

| typedef psa_status_t(* psa_drv_hash_finish_t) (psa_drv_hash_context_t *p_context, uint8_t *p_output, size_t output_size, size_t *p_output_length) |
The function prototype for the finish operation of a hash (message digest) operation.
Functions that implement this prototype should be named in the following convention:
Where ALGO is the name of the underlying algorithm
| [in,out] | p_context | A hardware-specific structure for the previously started hash operation to be fiinished |
| [out] | p_output | A buffer where the generated digest will be placed |
| [in] | output_size | The size in bytes of the buffer that has been allocated for the p_output buffer |
| [out] | p_output_length | The number of bytes placed in p_output after success |
| PSA_SUCCESS | Success. |
Definition at line 127 of file crypto_accel_driver.h.
| typedef void(* psa_drv_hash_abort_t) (psa_drv_hash_context_t *p_context) |
The function prototype for the abort operation of a hash (message digest) operation.
Functions that implement this prototype should be named in the following convention:
Where ALGO is the name of the underlying algorithm
| [in,out] | p_context | A hardware-specific structure for the previously started hash operation to be aborted |
