Parameters
| No. | Argument Type | Argument Name | Type | Description |
|---|---|---|---|---|
| 1 | st_Crypto_Hash_Blake_Ctx* | ptr_blakeCtx_st | Output | BLAKE variant algorithm and crypto handler selection |
| 2 | crypto_Hash_Algo_E | blakeAlgorithm_en | Input | Hash algorithm selection |
| 3 | uint8_t* | ptr_blakeKey | Input | (Optional) Key needed for the BLAKE algorithm Else NULL |
| 4 | uint32_t | keySize | Input | (Optional) Key length in bytes needed for the BLAKE algorithm else 0. Maximum length of key is allowed 64 bytes for BLAKE2b and up to 32 bytes for BLAKE2s. |
| 5 | uint32_t | digestSize | Input | Hash length required by user in bytes in multiples of 8 |
| 6 | crypto_HandlerType_E | blakeHandlerType_en | Input | Input to select the crypto engine i.e., SW library or HW crypto |
| 7 | uint32_t | blakeSessionId | Input | It defines the session ID, must be more than zero |
