#include <crypto/nrf_cc310_platform/include/nrf_cc3xx_platform_shadow_key.h>

Function to finalize the encryption/decryption operation.

The tag buffer is used as an ouput buffer when performing authenticated encryption and an input buffer when performing authenticated decryption. The tag_length parameter is only used when the tag is an output buffer (authenticated encryption).

Parameters

[in,out]	ctx	Pointer to the derived key context.
[out]	output	Pointer to the output buffer.
[in]	output_size	The size of the output buffer in bytes.
[out]	output_length	The number of bytes written to the output buffer.
[in,out]	tag	Pointer to the authentication tag.
[in]	tag_size	The size of the tag buffer in bytes.
[out]	tag_length	The number of bytes written to the tag buffer.

Returns

NRF_CC3XX_PLATFORM_SUCCESS on success, otherwise a negative value.
