The official Tesla App is unfortunately not available for Ubuntu Phone. And there is no indication that it will be on my next phone, the Librem5 from Purism. On the bright side, from the computer I can control my car using the VisibleTesla desktop app running inside a docker container. But the best part about… Continue reading Why I deactivated Tesla app access

Verifying downloads
Last week I stumbled across a post from last year, where somebody described how it was impossible to download an important infrastructure program securely on Windows. My first reaction was of course to pity the poor souls that are still stuck with Windows. How easy is it to just type apt-get install and have all… Continue reading Verifying downloads
connecting home securely
It has been probably close to a decade that I run a small server at home. At first it was only because I could not find a web hosting company that would serve my fcgi libwt apps at an affordable price. Then I added this blog to it. In the meantime I added a lot… Continue reading connecting home securely

On one hand, I don’t know if… Continue reading locally encrypted remote storage
Full disk encryption with the crypto stick
Last week I finished the udacity applied cryptography course. I did not as well as in the other courses, nonetheless I learned a lot and it was (as always) really interesting. We learned about symmetric and asymmetric encryption, hashes as well as key exchange and management. Each week in addition to the regular homework, we… Continue reading Full disk encryption with the crypto stick
Playing with Smart-Cards
Ever since reading the book “Kryptographie und IT-Sicherheit” where I first learned about how SmartCards work, I wanted to do some SmartCard programming. In the book it describes some inner workings of Smart Cards, and that some of them have a small Java VM inside. But it turned out that the entry was not as… Continue reading Playing with Smart-Cards
