QuickHash Library C++ Interface


void Final( unsigned char* pDest );



    [out] Pointer to the memory buffer that will receive the message digest.


Call this member function to retrieve the message digest from the CRIPEMD160 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 CRIPEMD160::DIGESTSIZE bytes.

After the Final method is performed, the CRIPEMD160 object is initialized for new calculations, as it would be constructed again.


#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[ CRIPEMD160::DIGESTSIZE ];

    //Instantiate a CRIPEMD160 object

    CRIPEMD160 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

    return 0;
