Generate an MD5 hash from a string.
This form is AJAX enabled, so using the submit button is not necessary unless you aren't using JavaScript.
I find this useful to generate a starter password for a new web application. I wouldn't type anything important into this form.
Source Code:
md5.php
<script language="javascript" type="text/javascript">
function handleHttpResponse() {
if (http.readyState == 4) {
document.output.output.value=http.responseText;
}
}
function getmd5() {
var md5input = document.getElementById("input").value;
http.open("GET", "md5_worker.php?input=" + escape(md5input), true);
http.onreadystatechange = handleHttpResponse;
http.send(null);
}
function getHTTPObject() {
if (typeof XMLHttpRequest != 'undefined') {
return new XMLHttpRequest();
}
try {
return new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try {
return new ActiveXObject("Microsoft.XMLHTTP");
} catch (e) {}
}
return false;
}
var http = getHTTPObject(); // We create the HTTP Object
</script>
<?php
if (@$_POST['input']) {
$input = $_POST['input'];
$input = substr($input,0,255);
$output = md5($input);
}
?>
<h3>Generate an MD5 sum from a string.</h3>

md5_worker.php
<?php

$input = substr($input,0,255);
echo md5($input);
}
?>
