Workaround for the deprecated EncryptString and DecryptString methods

Shows how to replace the deprecated EncryptString and DecryptString methods. (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_CryptAlgorithm("aes");
    crypt.put_CipherMode("cbc");
    crypt.put_KeyLength(128);
    crypt.put_PaddingScheme(0);
    crypt.SetEncodedKey("000102030405060708090A0B0C0D0E0F","hex");
    crypt.SetEncodedIV("000102030405060708090A0B0C0D0E0F","hex");

    success = false;

    crypt.put_Charset("utf-8");
    String plainText = "text to be encrypted";

    //  ------------------------------------------------------------------------
    //  The EncryptString and DecryptString methods are deprecated:

    CkByteData encryptedBytes = new CkByteData();
    success = crypt.EncryptString(plainText,encryptedBytes);

    String decryptedStr = crypt.decryptString(encryptedBytes);
    System.out.println("Decrypted: " + decryptedStr);

    //  ------------------------------------------------------------------------
    //  Replace the above CkByteData usage with the following code:
    //  (Chilkat is moving away from using CkByteData)

    CkBinData bd = new CkBinData();
    bd.AppendString(plainText,"utf-8");

    //  in-place encrypt
    crypt.EncryptBd(bd);

    //  in-place decrypt
    crypt.DecryptBd(bd);
    decryptedStr = bd.getString("utf-8");
    System.out.println("Decrypted: " + decryptedStr);
  }
