super specific login program(ugly draft code) - ICE_ - 12-13-2012
hey guys! here's a little program I made when I was bored in computer science, the code is SUPER ugly because its just a draft for a different program I'm going to make that will implement it, here it is:
Code:
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.DataInputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileWriter;
import java.io.InputStreamReader;
import java.util.Arrays;
import java.util.Scanner;
import java.util.UUID;
/**
* This program demonstrates how to generate a secret-key object for
* HMAC-MD5, and initialize an HMAC-MD5 object with it.
*/
