algorithm context |
| 2 | crypto_HandlerType_E | handlerType_en | Input | Enum for
crypto operation handler i.e., SW, HW |
| 3 | uint8_t* | ptr_key | Input | Key for the
AES-GMAC cipher operation |
| 4 | uint32_t | keyLen | Input | Key length for
the AES-GMAC algorithm in bytes |
| 5 | uint32_t | sessionID | Input | It defines the
session ID, must be more than zero |
Returns
| Return Type | Description |
|---|
| crypto_Mac_Status_E | Function
returns the status of the API. |
Prerequisites
- To use the HW handler, the
algorithm must be enabled in Crypto v4 in MPLAB® Code Configurator.
- To use the SW handler, the
algorithm must be enabled in wolfCrypt, and linked to Crypto V4 in MPLAB® Code
Configurator.
