Parameters

[in,out]	operation	Pointer to the AEAD operation structure.
[out]	ciphertext	Output buffer for remaining ciphertext (typically none for CCM).
[in]	ciphertext_size	Size of the ciphertext buffer.
[out]	ciphertext_length	Pointer to store the actual ciphertext length.
[out]	tag	Output buffer for the authentication tag.
[in]	tag_size	Size of the tag buffer.
[out]	tag_length	Pointer to store the actual tag length.

Return values

PSA_SUCCESS	Operation finished successfully; tag generated.
PSA_ERROR_BUFFER_TOO_SMALL	Tag buffer too small.
PSA_ERROR_BAD_STATE	Operation not initialized.
