Onion Service Authorization

Hi,

i am having trouble setting up client authorization for my hidden service.

I created a hidden service with client authorization.

To set up my Whonix client machine, i followed the instructions from here: http://www.dds6qkxpwdeubwucdiaord2xgbbeyds25rbsgr73tbfpqpt4a6vjwsyd.onion/wiki/Onion_Services#Onion_Service_Authentication_Client_Setup

But when browsing the site, there is a small window asking for the key. When entering the key it says, that it is of the wrong format.

Any ideas?

thanks for your help!

I tried that before and failed to figure that out.
