nn::crypto::DecryptAndVerifyAes128Ccm Function

bool DecryptAndVerifyAes128Ccm(
     void * pDst,
     const void * pSrc,
     size_t srcSize,
     const void * pKey
);

	Name	Description
out	pDst	Pointer to the buffer storing the decryption results. This buffer must be at least as big as srcSize - GENERATE_HEADER_SIZE.
in	pSrc	Pointer to the buffer storing the ciphertext.
in	srcSize	Ciphertext size in bytes.
in	pKey	Pointer to the buffer storing the key. The key is 16 bytes in length.

Returns whether the validity test succeeded. If TRUE, there is likely no tampering. If FALSE, the file has likely been tampered with.

Decrypts and tests for tampering.

Decrypts data encrypted using the EncryptAndGenerateAes128Ccm function, and tests the decrypted data to see if it has been tampered with.

Data decrypted by this function is reduced in size by GENERATE_HEADER_SIZE (that is, 16) bytes. Consequently, the buffer pointed to by pDst must be big enough to hold srcSize - GENERATE_HEADER_SIZE bytes of data.
