nn::crypto::CtrEncryptor::Encrypt Member Function

static size_t Encrypt(
     void * pDst,
     size_t dstSize,
     const void * pSrc,
     size_t srcSize,
     const void * pIv,
     size_t ivSize,
     const BlockCipher & c
);

	Name	Description
out	pDst	Pointer to the buffer storing the encryption results.
in	dstSize	Size of the buffer pointed to by pDst.
in	pSrc	Pointer to the buffer storing the plaintext.
in	srcSize	Plaintext size in bytes.
in	pIv	Pointer to the buffer storing the IV.
in	ivSize	IV size in bytes.
in	c	Instance of the block encryption implementation used in encryption.

Returns the number of bytes written to pDst.

Handles batch encryption when in CTR mode.

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

For c, specify an instance of a class derived from the BlockCipher class that implements the block cipher used in encryption. You must have previously used the BlockCipher::SetKey function to set the key used in encryption.

The function fails and displays an error if the size of the return value is larger than the buffer size specified in dstSize. Data is not written to the buffer beyond the size specified in dstSize. If the size of the return value is not larger than dstSize, the function indicates a successful completion and writes the size of the return value in pDst.

If this function fails, encryption cannot continue. You must then try again, starting by calling the Initialize function.
