Workaround for the deprecated Crypt2.VerifyBytes method

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

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

void ChilkatSample(void)
    {
    CkCrypt2 crypt;

    const char *sigPath = "c:/someDir/example.p7s";
    const char *originalDataPath = "c:/someDir/example.dat";

    //  ------------------------------------------------------------------------
    //  The VerifyBytes method is deprecated:

    CkByteData detachedSigBytes;
    detachedSigBytes.loadFile(sigPath);

    CkByteData originalDataBytes;
    originalDataBytes.loadFile(originalDataPath);

    bool verified = crypt.VerifyBytes(originalDataBytes,detachedSigBytes);

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

    CkBinData bdSig;
    bdSig.LoadFile(sigPath);

    CkBinData bdOrigData;
    bdOrigData.LoadFile(originalDataPath);

    const char *encoding = "base64";
    crypt.put_EncodingMode(encoding);
    verified = crypt.VerifyBdENC(bdOrigData,bdSig.getEncoded(encoding));
    }
