If not already done, initialize the HASH peripheral then processes pInBuffer.
- Note
- Field hhash->Phase of HASH handle is tested to check whether or not the Peripheral has already been initialized.
- The input buffer size (in bytes) must be a multiple of 4 otherwise, the HASH digest computation is corrupted.
- Parameters
-
hhash HASH handle. pInBuffer pointer to the input buffer (buffer to be hashed). Size length of the input buffer in bytes, must be a multiple of 4. Algorithm HASH algorithm.

| uint8_t * | pOutBuffer, | ||
| uint32_t | Timeout | ||
| ) |
Return the computed digest.
- Note
- The API waits for DCIS to be set then reads the computed digest.

Initialize the HASH peripheral, next process pInBuffer then read the computed digest.
- Note
- Digest is available in pOutBuffer.
- Parameters

| uint8_t * | pInBuffer, | ||
| uint32_t | Size, | ||
| uint32_t | Algorithm | ||
| ) |
Initialize the HASH peripheral then initiate a DMA transfer to feed the input buffer to the Peripheral.
- Note
- If MDMAT bit is set before calling this function (multi-buffer HASH processing case), the input buffer size (in bytes) must be a multiple of 4 otherwise, the HASH digest computation is corrupted. For the processing of the last buffer of the thread, MDMAT bit must be reset and the buffer length (in bytes) doesn't have to be a multiple of 4.
- Parameters
-
hhash HASH handle. pInBuffer pointer to the input buffer (buffer to be hashed). Size length of the input buffer in bytes. Algorithm HASH algorithm.
- Return values

| ) |
Initialize the HASH peripheral in HMAC mode then initiate the required DMA transfers to feed the key and the input buffer to the Peripheral.
