CSHA256::Final
void Final( unsigned char* pDest );
Parameters
pDest
[out] Pointer to the memory
buffer that will receive the message digest.
Remarks
Call this member function to retrieve the message digest from the CSHA256
object. The digest is retrieved in the memory buffer
pointed by pDest. The size of the memory buffer pointed by pDest
must be at least CSHA256::DIGESTSIZE bytes.
After the Final method is performed, the CSHA256
object is initialized for new calculations, as it would be constructed
again.
Example
#include <fstream>
#include <QuickHash.h>
using namespace std;
using namespace QuickHash;
const unsigned int BUFF_SIZE = 1024;
int main()
{
fstream file( "c:\\test.txt", ios::in | ios::binary );
if( !file )
return 1;
unsigned char buff[ BUFF_SIZE ];
unsigned char digest[ CSHA256::DIGESTSIZE ];
//Instantiate a CSHA256 object
CSHA256 hash;
//Calculate the digest by calling Update for each block of the file
while( !file.eof() )
{
file.read( ( char* )buff, BUFF_SIZE );
hash.Update( buff, file.gcount() );
}
//Do final changes and get the digest
hash.Final( digest );
//Use the digest
//...
file.close();
return 0;
