Java Writing Base64 cipher

BASE64 encryption algorithm, widely used, especially in e-mail transmission, has a great use

The program code written in Java is as follows

Importjava.awt.BorderLayout;ImportJava.awt.EventQueue;Importjava.awt.event.ActionEvent;ImportJava.awt.event.ActionListener;Importjava.io.IOException;ImportJavax.swing.JFrame;ImportJavax.swing.JPanel;ImportJavax.swing.border.EmptyBorder;ImportJavax.swing.JTextArea;ImportJavax.swing.JButton; Public classBase64frameextendsJFrame {PrivateJPanel ContentPane; PrivateJButton Btnnewbutton; PrivateJTextArea TextArea; PrivateJButton btnnewbutton_1; PrivateJTextArea textarea_1; /*** Launch the application. */     Public Static voidMain (string[] args) {Eventqueue.invokelater (NewRunnable () { Public voidrun () {Try{base64frame frame=NewBase64frame (); Frame.setvisible (true); } Catch(Exception e) {e.printstacktrace ();    }            }        }); }    /*** Create the frame. */     PublicBase64frame () {Settitle ("Base64 cipher"); Setresizable (false);        Setdefaultcloseoperation (Jframe.exit_on_close); SetBounds (100, 100, 505, 405); ContentPane=NewJPanel (); Contentpane.setborder (NewEmptyborder (5, 5, 5, 5));        Setcontentpane (ContentPane); Contentpane.setlayout (NULL); TextArea=NewJTextArea (); Textarea.setbounds (14, 13, 471, 136);                Contentpane.add (TextArea); Textarea_1=NewJTextArea (); Textarea_1.setbounds (14, 206, 471, 151);                Contentpane.add (textarea_1); Btnnewbutton=NewJButton ("Encoding"); Btnnewbutton.setbounds (14, 166, 113, 27);                Contentpane.add (Btnnewbutton); Btnnewbutton_1=NewJButton ("Decode"); Btnnewbutton_1.setbounds (372, 162, 113, 27);        Contentpane.add (btnnewbutton_1); Btnnewbutton.addactionlistener (NewActionListener () {@Override Public voidactionperformed (ActionEvent e) {textarea_1.settext (Base64util.encryptbase64 (Textarea.gettext (). GetByt                            ES ()));        }        }); Btnnewbutton_1.addactionlistener (NewActionListener () {@Override Public voidactionperformed (ActionEvent e) {Try{textarea_1.settext (Base64util.decryptbase64 (Textarea.gettext ())); } Catch(IOException E1) {//TODO auto-generated Catch blockE1.printstacktrace ();    }                            }        }); }}

Importjava.io.IOException;ImportDecoder.base64decoder;ImportDecoder.base64encoder; Public classBase64util { Public StaticString EncryptBase64 (byte[] data) {        return NewBase64encoder (). Encode (data);//Coding Algorithm    }         Public StaticString decryptBase64 (String data)throwsioexception{byte[] Resultbytes =NewBase64decoder (). Decodebuffer (data);//data on behalf of ciphertext        return NewString (resultbytes);//returns the string form of a byte array    }}

The Base64util tool class is provided by the Geek College;

This requires support for the Sun.misc.BASE64Decode.jar JDK Development Kit, which can be downloaded from the JDK's website or by clicking this link.
