nn::crypto::CcmDecryptor::DecryptAndVerify Member Function

static bool DecryptAndVerify(
     void * pDst,
     size_t dstSize,
     const void * pAdata,
     size_t adataSize,
     const void * pCdata,

	Name	Description
out	pDst	Pointer to the buffer storing the decryption results.
in	dstSize	Size of the buffer pointed to by pDst.
in	pAdata	Pointer to the buffer storing the Adata.
in	adataSize	Adata size in bytes.
in	pCdata	Pointer to the buffer storing the Cdata.
in	cdataSize	Cdata size in bytes.
in	pIv	Pointer to the buffer storing the IV.
in	ivSize	IV size in bytes.
in	pMac	Pointer to the buffer storing the MAC.
in	macSize	MAC size in bytes.
in	c	Instance of the block cipher implementation used in decryption.

Returns whether MAC verification succeeded. Returns TRUE if MAC verification succeeded and FALSE otherwise. If TRUE, there is likely no tampering.

Handles batch decryption and verification when in CTR mode.

When all data is loaded into memory, you can call this function to decrypt and verify all of the data at once.

For c, specify the same key used in encryption for the block cipher of the same algorithm used in encryption.

Specify a pointer to an IV object in pIv, and its size in ivSize. You must specify the same IV, adataSize, and macSize values as those used for encryption.

You must specify the same cdataSize value as the pdataSize value used for encryption.
