This function is used to perform the CHACHA-POLY encryption and authentication operation.

Returns:: CRYS_OK on success.; A non-zero value on failure as defined crys_chacha_poly_error.h.

Parameters:

[in]	pNonce	A pointer to a buffer containing the nonce value.
[in]	pKey	A pointer to the user's key buffer.
[in]	encryptDecryptFlag	A flag specifying whether the CHACHA-POLY should perform an Encrypt or Decrypt operation.
[in]	pAddData	A pointer to the buffer of the additional data to the POLY. The pointer does not need to be aligned. must not be null.
[in]	addDataSize	The size of the input data. must not be 0.
[in]	pDataIn	A pointer to the buffer of the input data to the CHACHA. The pointer does not need to be aligned. must not be null.
[in]	dataInSize	The size of the input data. must not be 0.
[out]	pDataOut	A pointer to the buffer of the output data from the CHACHA. must not be null.
[in,out]	macRes	Pointer to the MAC result buffer.
