[Java] Generate MD5 Hash

[Praetorian503]

Here's the simple java security tutorial on generating MD5 hash of input text using java.security API functions.

import java.security.MessageDigest;

public class MD5Class
{
  public static void main(String args[]) throws Exception
  {
    String input = "test text";

    MessageDigest m = MessageDigest.getInstance("MD5");
    m.update(input.getBytes("UTF8"));
    byte s[] = m.digest();
    String result = "";

    for (int i = 0; i < s.length; i++)
    {
      result += Integer.toHexString((0x000000ff & s[i]) | 0xffffff00).substring(6);
    }

    System.out.println("MD5 Hash of input text" + input);
    System.out.println(result);
  }
}
