Workaround for the deprecated Crypt2.VerifyBytesENC method

Shows how to replace the deprecated VerifyBytesENC 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[])
  {
    CkCrypt2 crypt = new CkCrypt2();

    //  Encoding mode property must match the encoding of the detached signature.
    crypt.put_EncodingMode("base64");

    String originalDataPath = "c:/someDir/example.dat";
    String base64_detached_signature = "....";

    //  ------------------------------------------------------------------------
    //  The VerifyBytesENC method is deprecated:

    CkByteData originalDataBytes = new CkByteData();
    originalDataBytes.loadFile(originalDataPath);

    boolean verified = crypt.VerifyBytesENC(originalDataBytes,base64_detached_signature);

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

    CkBinData bdOrigData = new CkBinData();
    bdOrigData.LoadFile(originalDataPath);

    verified = crypt.VerifyBdENC(bdOrigData,base64_detached_signature);
  }
}
