Java Requires Chilkat v11.0.0+

Workaround for the deprecated Crypt2.DecryptBytesENC method

Shows how to replace the deprecated DecryptBytesENC 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();

    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;

    //  ------------------------------------------------------------------------
    //  The EncryptBytesENC and DecryptBytesENC methods are deprecated:

    CkByteData unencryptedBytes = new CkByteData();
    unencryptedBytes.appendEncoded("AABBCCDDEEFF01020304","hex");

    CkByteData decryptedBytes = new CkByteData();

    crypt.put_EncodingMode("hex");
    String encryptedAsHex = crypt.encryptBytesENC(unencryptedBytes);
    System.out.println("Encrypted: " + encryptedAsHex);

    success = crypt.DecryptBytesENC(encryptedAsHex,decryptedBytes);

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

    CkBinData bd = new CkBinData();
    bd.AppendEncoded("AABBCCDDEEFF01020304","hex");

    //  in-place encrypt, then get as hex.
    crypt.EncryptBd(bd);
    encryptedAsHex = bd.getEncoded("hex");
    System.out.println("Encrypted: " + encryptedAsHex);

    //  load from hex, then decrypt.
    CkBinData bd2 = new CkBinData();
    bd2.AppendEncoded(encryptedAsHex,"hex");
    crypt.DecryptBd(bd2);
    System.out.println("Decrypted: " + bd2.getEncoded("hex"));
  }
