QuickHash Library C++ Interface

CMD5::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 CMD5 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 CMD5::DIGESTSIZE bytes.

After the Final method is performed, the CMD5 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[ CMD5::DIGESTSIZE ];

    //Instantiate a CMD5 object

    CMD5 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;
}
