severity 839575 serious thanks I digged a bit deeper. Tinyca 0.7.5-5 worked for me in Jessie. So I tried 0.7.5-6 there. It worked, too! After updating openssl from 1.0.2g-2 (jessie-backports) to 1.1.0e-1 (stretch) tinyca stopped working!
The last thing what happened when creating a CA is a messagebox saying that the RSA key will be produced (in german: "Die Erstellung des RSA Schlüssels läuft...") but after a while the slider stopped moving and the messages mentioned by Richard appeared in the console window. Tinyca should be fixed or removed from stretch.
