convert password encryption from java to php

Question

I\'m trying to create a PHP version of an existing JSP program, however I\'m stuck at the password encryption part.

Could you please tell me how to convert this one?

UPDATE: There are some discrepancies between the two versions. To fix this see @bobince answer.Here is the test code:

Java

package tests;

import java.security.MessageDigest;

/**

public class Md5Test {
    public static String encryptPassword(String password) {
        String encrypted = "";
        try {
            MessageDigest digest = MessageDigest.getInstance("MD5");
            byte[] passwordBytes = password.getBytes();

            digest.reset();
            digest.update(passwordBytes);
            byte[] message = digest.digest();

            StringBuffer hexString = new StringBuffer();
            for (int i = 0; i < message.length; i++) {
                hexString.append(Integer.toHexString(
                        0xFF & message[i]));
            }
            encrypted = hexString.toString();
        }
        catch (Exception e) {
        }
        return encrypted;
    }

    public static void main(String[] args) {
        System.out.println("Pass1 md5 = " + encryptPassword("Test123FORXTREMEpass"));
        System.out.println("Pass1 md5 = " + encryptPassword("Ijdsaoijds"));
        System.out.println("Pass1 md5 = " + encryptPassword("a"));
        System.out.println("Pass1 md5 = " + encryptPassword(" "));
    }

}


Output:
Pass1 md5 = dc3a7b42a97a3598105936ef22ad2c1
Pass1 md5 = df7ca542bdbf7c4b8776cb21c45e7eef
Pass1 md5 = cc175b9c0f1b6a831c399e269772661
Pass1 md5 = 7215ee9c7d9dc229d2921a40e899ec5f

PHP

";
echo "Pass2 md5 = ".md5("Ijdsaoijds")."
";
echo "Pass3 md5 = ".md5("a")."
";
echo "Pass4 md5 = ".md5(" ")."
";
?>

output:

Pass1 md5 = dc3a7b42a97a35981059036ef22ad2c1
Pass2 md5 = df7ca542bdbf7c4b8776cb21c45e7eef
Pass3 md5 = 0cc175b9c0f1b6a831c399e269772661
Pass4 md5 = 7215ee9c7d9dc229d2921a40e899ec5f
