Workaround for the deprecated Crypt2.HashBytes method

Shows how to replace the deprecated HashBytes 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();

    crypt.put_HashAlgorithm("sha256");

    String path = "c:/someDir/example.dat";

    //  ------------------------------------------------------------------------
    //  The HashBytes method is deprecated:

    CkByteData inData = new CkByteData();
    inData.loadFile(path);

    CkByteData outData = new CkByteData();

    success = crypt.HashBytes(inData,outData);

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

    CkBinData bdIn = new CkBinData();
    bdIn.LoadFile(path);

    crypt.put_EncodingMode("base64");
    String base64_hash = crypt.hashBdENC(bdIn);
  }
