CSHA384::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 CSHA384 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 CSHA384::DIGESTSIZE bytes.

After the Final method is performed, the CSHA384 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[ CSHA384::DIGESTSIZE ];

    //Instantiate a CSHA384 object

    CSHA384 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;
}
