Java Requires Chilkat v11.0.0+

Workaround for the deprecated Crypt2.OpaqueVerifyString method

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

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();

    //  Specifies how the original data bytes are converted to characters
    crypt.put_Charset("utf-8");

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

    //  ------------------------------------------------------------------------
    //  The OpaqueVerifyString method is deprecated:

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

    String originalText = crypt.opaqueVerifyString(inData);

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

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

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

    //  Indicate how the bytes are converted to chars by passing the charset.
    originalText = bd.getString("utf-8");
  }
