Workaround for the deprecated Crypt2.OpaqueVerifyString method

Shows how to replace the deprecated OpaqueVerifyString 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;

    //  Specifies how the original data bytes are converted to characters
    crypt.put_Charset("utf-8");

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

    //  ------------------------------------------------------------------------
    //  The OpaqueVerifyString method is deprecated:

    CkByteData inData;
    inData.loadFile(path);

    const char *originalText = crypt.opaqueVerifyString(inData);

    //  ------------------------------------------------------------------------
    //  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);

    //  Indicate how the bytes are converted to chars by passing the charset.
    originalText = bd.getString("utf-8");
    }
