Workaround for the deprecated Crypt2.OpaqueVerifyBytesENC method

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

import com.chilkatsoft.*;

public class ChilkatExample {

  static {
    try {
        System.loadLibrary("chilkat");
    } catch (UnsatisfiedLinkError e) {
      System.err.println("Native code library failed to load.\n" + e);
      System.exit(1);
    }
  }

  public static void main(String argv[])
  {
    boolean success = false;

    CkCrypt2 crypt = new CkCrypt2();

    crypt.put_EncodingMode("base64");

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

    CkByteData outData = new CkByteData();

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

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

    CkBinData bd = new CkBinData();
    bd.AppendEncoded("base64 encoded p7m","base64");

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