Wie man unter Typo3 URLs mit der uid des eingeloggten Benutzers erzeugt

Das Einfügen eines Links mit der Benutzer-ID ist nicht-trivial, da auf die uid nicht mit TypoScript zugegriffen werden kann. Man muß dazu PHP bemühen und eine user function user_* beispielsweise in der Datei fileadmin/templates/miscfunctions.php anlegen:

function user_getuserid($content,$conf)
{
        return $GLOBALS['TSFE']->fe_user->user[uid];
}

Anschließend wird im Template im Setup-Bereich die PHP-Datei eingebunden:

 includeLibs.get_userid = fileadmin/templates/miscfunctions.php

Nun kann man das PHP-Skript mit Typoscript auslesen:

temp.mein_link = COA
temp.mein_link.wrap (
    <a href="irgendeineurl.php?uid=|"> mein_link </a>
    )
temp.mein_link.10 = UINT
temp.mein_link.10.userFunc = user_getuserid

openssl speed measurements

I recently did some speed measurements for crypto algorithms with different hardware. The background was to compare the SSL negotation/handshake drawback when switching from 1024 to 2048 bit with RSA and DSA, especially for openvpn.

It shows that even with the oldest hardware (166 MHz Pentium) its affordable in terms of speed to use a 2048 bit RSA key. Note that normally a public key handshake is only done at the beginning of the communication process and then perhaps every hour. With hybrid algorithms the speed of the communication path depends from the symetric cipher.
