<div class="textblock"><p>A client class to access kdesud, the KDE su daemon. </p>
<p>Kdesud can assist in password caching in two ways:</p>
<ul>
<li>For high security passwords, like for su and ssh, it executes the password requesting command for you. It feeds the password to the command, without ever returning it to you, the user. The daemon should be installed setgid nogroup, in order to be able to act as an inaccessible, trusted 3rd party. See exec, setPass, delCommand.</li>
</ul>
<ul>
<li>For lower security passwords, like web and ftp passwords, it can act as a persistent storage for string variables. These variables are returned to the user, and the daemon doesn't need to be setgid nogroup for this. See setVar, delVar, delGroup. </li>
</ul>
