Enkripsi

Enkripsi dan Dekripsi hmm...
mungkin bagi beberapa orang kedua kata ini terasa sangat begitu asing.
Enkripsi sebenernya adalah proses untuk “mengaburkan” atau " informasi untuk membuat informasi tersebut tidak bisa dibaca tanpa pengetahuan khusus. Sedangkan Dekripsi yaitu kebalikan dari proses Enkripsi itu sendiri, atau mungkin bisa di sebut deklarasi Enkripsi. Algoritma penyandian yang paling klasik adalah dengan subtitution, yaitu menukarkann huruf yang satu dengan yang lain, sedangkan dekripsi adalah kebalikan dari enkripsi yaitu memecahkan informasi yang telah dikaburkan oleh enkripsi.

biasanya enkripsi dan dekripsi itu di aplikasikan ke dalam password

algoritma enkripsi yang cukup terkenal adalah caesar cipher




seperti gambar diatas caesar cipher melakukan metode geser dengan 3 huruf atau angka

semisal
Huruf asli : a b c d e f g h i j k l m n o p q r s t u v w x y z
Huruf sandi: d e f g h i j k l m n o p q r s t u v w x y z a b c



Pertama kali algoritma kriptografi ini digunakan sebagai petunjuk dalam perang. Menurut sejarah pada tahun 1900 SM Julius Caesar dikenal sebagai orang yang pertama kali telah mengembangkan algoritma kriptografi untuk mengirimkan pesan ketentaranya. Dan kurang dari 500 tahun yang lalu. Enkripsi digunakan untuk dokumen religius dan formula, serta komunikasi pemerintah

program untuk algoritma caesar cipher diatas sudah saya bahas di postingan sebelumnya
pada zaman sekarang banyak sekali kode kode sandi yang telah dibuat dari kalangan ilmuan sampai kalangan anak muda.

dulu waktu saya ngambil mta kuliah ethical hacking pernah mencoba mendekripsikan WEP dengan menggunakan BackTrack2 dengan mencrack WEP teman teman bisa lebih menegerti tentang konsep dari enkripsi dan dekripsi,

SWING dan AWT

Apakah sebenarnya swing dan AWT itu?? Makanan apa tuh..?? :D Klo masih terdengar asing maka akan Ane jelaskan. Singkatnya swing dan AWT (Abstract Window Toolkit) adalah penyedia komponen window/GUI (Graphical User Interface) pada java. Kalo anda orang yang sangat awam..awam..awam mengenai ini, bahasa bego-nya swing dan AWT adalah komponen pada java untuk membuat tampilan grafis. Kalo g ngerti juga silahkan kursus dulu di tempat-tempat kursus terdekat.. :p
Okeh, saya gkan berlama-lama menyesatkan anda pada semua tetek bengek teori bahasa Java yg mungkin membingungkan anda. Saya akan mencoba menjelaskan secara langsung dengan sebuah pembuatan program “Jendela Password”. Kayak gini nich tampilan outputnya :
 Dalam pembuatan program ini saya memakai :
  • Notepad ++, untuk text editor-nya. Yang lain juga bisa kaya notepad, edit plus, dll( yg simpel2 ajah).
  • Java Compiler(kudu/wajib ada!!!!), klo ga ada gimana mau buat program java, mas2/mbak2?? Untuk sekarang saya pake j2sdk1.4.2. Supaya bisa meng-compile Java di semua direktori, kita harus mengatur PATH-nya dulu (apa lagi ini!!!??). Sante ajach mas/mbak, gampank koq. Pertama klik kanan di My Computer > Properties.

Nanti langsung muncul jendela System Properties klik tab Advanced, di situ ada tombol Environment Variables, di klik trus muncul jendelanya.

Di jendela User Variables klik new, muncul jendela input New User Variables. Variable Name isi terserah yg kita mau, lalu Variable Value-nya diisi dengan direktori bin pada Java, misal defaultnya C:\j2sdk1.4.2\bin. Trus Tekan ok, ok, dan ok, restart deh. Gampank kan?? Udah gitu doank.
Yup pertama buka teks editornya lalu pilih menu File > Save As. Saya akan buat direktori baru C:\java.lat, simpan dengan nama PassFrame.java (nama File harus sama dengan nama public class-nya) di dalam direktori tersebut. Ketik program di bawah ini. baris yg ada tanda // cuma komentar :

import javax.swing.*; //pemanggilan seluruh kelas swing
import java.awt.*; //pemanggilan seluruh kelas awt
import java.awt.event.*; //pemanggilan kelas event yg berada dalam kelas awt

}

//menentukan aksi dari event dari tombol jCancel
//event tersebut akan di tangkap oleh jLogin_actionPerformed
public void jCancel_actionPerformed(ActionEvent e)
{
//aksinya adalah memunculkan kotak dialog "Anda telah keluar dari Program"
//dan keluar dari program
JOptionPane.showMessageDialog(null, "Anda telah keluar dari Program");
System.exit(0);
}
}

untuk mencoba isi ID, nama , dan passwordnya dengan :
ID : 1234
nama : kampreto
password : lupa

selamat mencoba!

Event Handling

Nah kali ini saya akan mencoba menjelaskan tentang Event Handling di Bahasa Java, langsung aja monggo di baca... :D
Dalam event handling pada Java ada empat bagian penting yang harus diketahui:
  1. Event Object merupakan object yang mendiskripsikan sebuah event yang di-trigger oleh event source.
  2. Event Handler merupakan method yang menerima event object dan melakukan respond yang sesuai dengan event object tersebut.
  3. Event Listener merupakan interface yang akan meng-handle event yang terjadi. setiap type event mempunyai interface yang bersesuaian. Listener tersebut harus diimplementasikan oleh class yang akan meng-handle event
  4. Event Source merupakan pembangkit / trigger sebuah event objects
Nah, setiap event object mempunyai  type event yang berbdea beda. sehingga kita harus menentukan type event sebelum menentukan jenis interface listener. karena setiap type event mempunyai jenis interface listener yang bersesuaian.
berikut ini type type event yang ada di Java :

  1. ActionEvent
  2. ItemEvent
  3. WindowEvent
  4. ContainerEvent
  5. ComponentEvent
  6. FocusEvent
  7. TextEvent
  8. KeyEvent
  9. MouseEvent
  10. AdjustmentEvent
Berikut ini Interface Listener
  1. ActionListener
  2. ItemListener
  3. WindowListener
  4. ContainerListener
  5. ComponentListener
  6. FocusListener
  7. TextListener
  8. KeyListener
  9. MouseListener
  10. MouseMotionListener
  11. AdjustmentListener
Berdasarkan tulisan diatas, setiap type event mempunyai satu jenis interface listener kecuali MouseEvent yang mempunyai dua jenis interface listener. dan setiap interface mempunyai method abstract yang harus di override class yang meng-impletasikan interface. event listener dan event handler terdapat pada package java.awt.event
Bagaimana event handling dalam Java? ada tiga langkah penting dalam event handling
  1. Deklarasikan class yang akan meng-handle event yang terjadi dan tuliskan code yang menyatakan class tersebut meng-implement interface listener
  2. Event source mendaftarkan sebuah listener melalui method add<type>Listener
  3. Kode yang mengimplementasikan method pada interface listener pada class yang akan meng-handle event. [ Override ]


    Dan Ini adalah Contoh yang Ane dapet dari file latihan ane... Ini skrip nya...    Contoh 1
    MouseEventsDemo.java
    package mouseeventsdemo;
    import java.awt.*;
    import java.awt.event.*;
    /**
    *
    * @author Ren
    */
    public class MouseEventsDemo extends Frame implements MouseListener, MouseMotionListener {  // Langkah 1
    TextField tf;
    public MouseEventsDemo( String title){
    super(title);
    tf = new TextField(60);
    addMouseListener(this); // Langkah 2
    }
    public void launchFrame() {
    /* Menambah komponen pada frame */
    add(tf, BorderLayout.SOUTH);
    setSize(300,300);
    setVisible(true);
    }
    public void mouseClicked(MouseEvent me) { // Langkah 3
    String msg = “Mouse clicked.”;
    tf.setText(msg);
    }
    public void mouseEntered(MouseEvent me) {
    String msg = “Mouse entered component.”;
    tf.setText(msg);
    }
    public void mouseExited(MouseEvent me) {
    String msg = “Mouse exited component.”;
    tf.setText(msg);
    }
    public void mousePressed(MouseEvent me) {
    String msg = “Mouse pressed.”;
    tf.setText(msg);
    }
    public void mouseReleased(MouseEvent me) {
    String msg = “Mouse released.”;
    tf.setText(msg);
    }
    public void mouseDragged(MouseEvent me) {
    String msg = “Mouse dragged at ” + me.getX()
    + “,” + me.getY();
    tf.setText(msg);
    }
    public void mouseMoved(MouseEvent me) {
    String msg = “Mouse moved at ” + me.getX()
    + “,” + me.getY();
    tf.setText(msg);
    }
    }
    main.java
    package mouseeventsdemo;
    /**
    *
    * @author Ren
    */
    public class Main {
    /**
    * @param args the command line arguments
    */
    public static void main(String[] args) {
    // TODO code application logic here
    MouseEventsDemo med = new MouseEventsDemo(“Mouse Events Demo”);
    med.launchFrame();
    }
    }

     
    Selamat belajar :D
