Here’s a simple Password Encryption technique using hashCode(), It is just a basic style that does not expose your password in the source code. The Password I have set is - password

import java.io.Console;

public class pwd {

public static void main(String[] args) {

char[] passwordChar = null;

Console console = System.console();

int hashInt = 1216985755;                     // value of the string “password”

try {

passwordChar = console.readPassword(”Enter Password : “);

} catch (NullPointerException e) {

System.out.println(”You Might Be Running The Program From An IDE , Try In Terminal”);

System.exit(1);

}

String passwordString = new String(passwordChar);

System.out.println(”The Hash value of the Entered String : ”

+ passwordString.hashCode());

System.out.println(”The Hash Value Required : ” + hashInt);

if (passwordString.hashCode() != hashInt)   {                     // hash coded check

System.out.println(”Wrong password”);

System.exit(2);

}

System.out.println(”Correct Password”);

}

}

There are better ways to do it than hashcode() method which is fragile, md5 or sha1 would be better techniques. The ONE TIME PADDING or encrypting the password using a secret key and storing it, but just for the program access I dont think it is that necessary, but the latter techniques will be useful while transmitting messages.
