Workaround for the deprecated Crypt2.OpaqueVerifyBytesENC method

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

#include <C_CkCrypt2.h>
#include <C_CkByteData.h>
#include <C_CkBinData.h>

void ChilkatSample(void)
    {
    BOOL success;
    HCkCrypt2 crypt;
    HCkByteData outData;
    HCkBinData bd;

    success = FALSE;

    crypt = CkCrypt2_Create();

    CkCrypt2_putEncodingMode(crypt,"base64");

    //  ------------------------------------------------------------------------
    //  The OpaqueVerifyBytesENC method is deprecated:

    outData = CkByteData_Create();

    success = CkCrypt2_OpaqueVerifyBytesENC(crypt,"base64 encoded p7m",outData);

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

    bd = CkBinData_Create();
    CkBinData_AppendEncoded(bd,"base64 encoded p7m","base64");

    //  If the opaque signature is validated, the contents of bd are replaced with the original data that was signed.
    //  
    success = CkCrypt2_OpaqueVerifyBd(crypt,bd);


    CkCrypt2_Dispose(crypt);
    CkByteData_Dispose(outData);
    CkBinData_Dispose(bd);

    }
