Compute a MAC in a single operation.

Parameters

[in]	attributes	Key attributes.
[in]	key_buffer	Key material buffer.
[in]	key_buffer_size	Size of the key buffer in bytes.
[in]	alg	MAC algorithm.
[in]	input	Input data to authenticate.
[in]	input_length	Length of the input data in bytes.
[out]	mac	Buffer to store the MAC.
[in]	mac_size	Size of the MAC buffer in bytes.
[out]	mac_length	Length of the generated MAC in bytes.

Return values

PSA_SUCCESS	The operation completed successfully.
PSA_ERROR_INVALID_HANDLE	The key handle is invalid.
PSA_ERROR_NOT_SUPPORTED	The algorithm is not supported.
PSA_ERROR_BUFFER_TOO_SMALL	The MAC buffer is too small.
