This small database shows how CAs are trusted across browsers (browser, webview, OS).
I created this database, because I had on my website big share of strange browsers (used by my visitors) and I needed to select right CA (to keep website working for them) - but there were no database like that.
Database is based on BenBE's SSLtest GitHub project.

I would like to say big thank you to Michal Špaček, for his advise, where to get data into this db.
