[in]	wrapping_key_data	Wrapping key material.
[in]	wrapping_key_size	Size of the wrapping key in bytes.
[in]	alg	Key wrapping algorithm.
[in]	data	Buffer containing the wrapped key data. The content of this buffer is unwrapped.
[in]	data_length	Size of the data buffer in bytes.
[out]	key	Key material of the unwrapped key.
[in]	key_size	Size of the buffer containing the unwrapped key.
[out]	key_length	On success, the number of bytes that make up the unwrapped key data
[out]	bits	On success, the number of bits that make up the unwrapped key data

Return values

PSA_SUCCESS	The operation completed successfully.
