Hi jleech
what is the different between SecureRandom class and Random class, should i use SecureRandom, my ideal is to genreate a completely reandom password, the code that show below which genreate 8 character between 0 to Z, and each character are in reandom, I thing that is quite secure, isn't it.
public boolean genPassword()
   int rand;
   char c;
   try
    while(password.length() < 8)
     rand=48+(int)(Math.random()*122);
     if((rand>=48&&rand<=57)||(rand>=65&&rand<=90)||(rand>=97&&rand<=122))
      c=(char)rand;
      password+=c;
    } //end of while loop
    return true;
   catch (Exception e)
    System.out.println(e.getMessage());
    setPassword("");
    return false;
}
