Example: Crypt2.SetEncodedIV method

Demonstrates how to call the SetEncodedIV method. Android™

// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.
package com.test;

import android.app.Activity;
import com.chilkatsoft.*;

import android.widget.TextView;
import android.os.Bundle;

public class SimpleActivity extends Activity {

  private static final String TAG = "Chilkat";

  // Called when the activity is first created.
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    CkCrypt2 crypt = new CkCrypt2();

    crypt.put_CryptAlgorithm("aes");
    crypt.put_CipherMode("cbc");
    crypt.put_KeyLength(256);

    //  Note: The lenght of the IV is equal to the block size of the symmetric encryption algorithm.
    //  The block size for AES is 16 bytes.  Therefore, the IV is 16 bytes regardless of the encryption strenght (128-bit, 256-bit, etc.)
    crypt.SetEncodedIV("000102030405060708090A0B0C0D0E0F","hex");

    //  ...
    //  ...

  }

  static {
      System.loadLibrary("chilkat");

      // Note: If the incorrect library name is passed to System.loadLibrary,
      // then you will see the following error message at application startup:
      //"The application <your-application-name> has stopped unexpectedly. Please try again."
