void emberAfPluginAesMacAuthenticate (const uint8_t * key, const uint8_t * message, uint8_t messageLength, uint8_t * out)
Compute the Cipher-based Message Authentication Code (CMAC) corresponding to the passed message and the passed key.
Parameters
| Type | Direction | Argument Name | Description |
|---|---|---|---|
| const uint8_t * | [in] | key | The key to be used to produce the cipher-based authentication code. |
| const uint8_t * | [in] | message | A pointer to the message for which a cipher-based authentication code should be computed. |
| uint8_t | [in] | messageLength | The length in bytes of the message to be authenticated. |
| uint8_t * | [out] | out | A pointer to a 16-byte area memory in which the resulting cipher-based authentication code will be stored. |
