Out of the blue my hosting provider finally offers one SSL certificate for free to use with my site. I’ve been using StartSSL certificates for my home servers for a long time now, but on the shared hosting servers I couldn’t just install my certificates and I felt the prices for regular ones are a pure rip-off.
In any case, kilgus.net finally got HTTPS support and I have adapted the site accordingly. I had to change all download links for this to work, so if I have missed a broken link or in case of any other problems, give me a shout.
