(C++) Workaround for the deprecated Crypt2.OpaqueVerifyBytes method

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

Note: This example requires Chilkat v11.0.0 or greater.

    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.
    bool success = crypt.OpaqueVerifyBd(bd);
    }
