[xquery-talk] Log users into existdb using md5 password (xquery)

[Luca Cervone]

Hi,
I need to log users into existdb using xquery. Of course I can use this code:

xquery version "3.0";
declare namespace exist = "http://exist.sourceforge.net/NS/exist";
declare namespace request="http://exist-db.org/xquery/request";
declare namespace xmldb="http://exist-db.org/xquery/xmldb";
declare option exist:serialize "method=json media-type=text/javascript";

let $userName := request:get-parameter("userName", ())
let $hash := request:get-parameter("hash", ())
let $login := xmldb:authenticate('/db', $userName, $hash)
return  <ajax-response>
            <success>{$login}</success>
        <username>{$userName}</username>
    </ajax-response>

The problem is that, due to the fact that I receive the password and the username from another service, I receive them in hash form encrypted with md5 (because the can't be passed in clear from a service to another).
But the xmldb:authenticate function needs the password in clear. How can I resolve this? Any idea? Is there a way to login 'manually' in xquery without using the authenticate function?
