I have to create a tag in a ViewHelper in my own extension, but I don’t know how to do it, that it works with Typo3. It has to use for an anchor element, but this anchor is only a small part of the ViewHelper. This is the URL:

/sonstiges/test?tx_review_listreviews[action]=list&tx_review_listreviews[controller]=Reviews

For which part I have to create the cHash?

And how can I create the cHash inside the Viewhelper?

clyssCan I use md5?

Is there any function which I use inside the ViewHelper class?

A example would be great!
