How to make hash in PHP and Node.js have the same value?

In node.js, I have: 

var h = crypto.createHash("md5");   // md5
h.update("AAA");
h.digest("hex");

In PHP I have:

md5("AAA");

However, both have different value. How can I make it the same? or else, what other algorithm I should use to make them the same, so that I can use it as signature calculation. Thanks.

Oppss.. actually. my mistake. when I test it, there is a bug.. it will md5 the same thing.

var hash = crypto.createHash('md5').update(password, 'latin1', 'latin1').digest('hex');

This worked for me. Try different encodings: 'utf8', 'ascii', or 'latin1'.

I had the same issue with creating hash for non UTF8 string : 

var non_utf8_str = "test_merchant;www.market.ua;DH783023;1415379863;1547.36;UAH;Процессор
Intel Core i5-4670 3.4GHz;Память Kingston DDR3-1600 4096MB
PC3-12800;1;1;1000;547.36";

The results in PHP and NodeJS was different until I used utf8 library. So following code works equivalent for both PHP and NodeJS :

crypto.createHash('md5').update(utf8.encode(non_utf8_str)).digest('hex');

Simple googling I did in the past gave me => http://japhr.blogspot.com/2010/06/md5-in-nodejs-and-fabjs.html

Node.js

Script:

var crypto = require('crypto');
var hash = crypto.createHash('md5').update('AAA').digest("hex");
console.log(hash);

Output:

alfred@alfred-laptop:~/node/hash$ node hash.js 
e1faffb3e614e6c2fba74296962386b7

PHP

Code

<?php
echo md5("AAA");

Output:

alfred@alfred-laptop:~/node/hash$ php md5.php 
e1faffb3e614e6c2fba74296962386b7

The output for both PHP and node.js are equal.

C extension

Also you might have look at https://github.com/brainfucker/hashlib which uses C implementation which is going to be faster.

Your code creates the same hash value for me, you might doing it wrong at some point
