My Agent Security Scenario: The Code -Father & Global Class

//the folder Sec is sub folder at examples folder
//I created to place my java classes in
package examples.Sec;

//and Decrypt Aglets
public class Global

 //before calling the ncrypt or decrypt method
 public static char array_char[];
 //at encrypt or decrypt method the character at
 //array of characters need to be casted into ASCII 
 //value and stored at array of integers to encounter
 //an arithmetic operation then the resulted value represent 
 //an ASCII code ,which will be casted to char and stored into
 //the array of characters 
 public static int array_int[];
 public static String array_in_string()

     //this method store the content 
  //of the array of characters into

  //theString may be the username in encrypted or clear text manner
