Workaround for the deprecated Crypt2.OpaqueVerifyBytes method

Shows how to replace the deprecated OpaqueVerifyBytes method. (Chilkat is moving away from the use of CkByteData.) C++

#include <CkCrypt2.h>
#include <CkByteData.h>
#include <CkBinData.h>

void ChilkatSample(void)
    {
    bool success = false;

    CkCrypt2 crypt;

    const char *path = "c:/someDir/example.p7m";

    //  ------------------------------------------------------------------------
    //  The OpaqueVerifyBytes method is deprecated:

    CkByteData inData;
    inData.loadFile(path);

    CkByteData outData;

    success = crypt.OpaqueVerifyBytes(inData,outData);

    //  ------------------------------------------------------------------------
    //  Workaround.
    //  (Chilkat is moving away from using CkByteData)

    CkBinData bd;
    bd.LoadFile(path);

    //  If the opaque signature is validated, the contents of bd are replaced with the original data that was signed.
    success = crypt.OpaqueVerifyBd(bd);
    }
