Question

I want to convert my JS variable to its MD5 hash.
I think using passing JS variable to PHP and again use in JS i think this can be possible?
If no, is there any other way to do the same?

An example for PeeHaa answer:

File ajax.php:

header( 'Content-type: text/javascript' );
$var = isset( $_GET['var'] ) ? $_GET['var'] : NULL;
echo md5( $var );

File test.html:

<script type="text/javascript">
function get_md5(str)
{
    var xmlhttp;
    if (window.XMLHttpRequest)
    {
        xmlhttp = new XMLHttpRequest();
    }
    else
    {
        xmlhttp = new ActiveXObject('Microsoft.XMLHTTP');
    }
    xmlhttp.onreadystatechange = function ()
    {
        if (xmlhttp.readyState == 4 && xmlhttp.status == 200)
        {
            document.getElementById('result').innerHTML = xmlhttp.responseText;
        }
    }
    xmlhttp.open('GET', '/ajax.php?var=' + str, true);
    xmlhttp.send();
}
function init_md5()
{
    var str = document.getElementById('str').value;
    get_md5(str);
}
</script>

str: <input type='text' id='str' value='test'/>
<input type='button' onclick='init_md5()' value='get md5'/><br/><br/>
md5: <span id='result'></span>
