They are asking you for your personal data, arrival date, travel itinerary, etc.
And, of course, the place where you will stay at your 10 days of mandatory quarantine.
In the background it's sending your entered zip code to a server, asking for a crypto public key in return.
You can check if your local health authority has a pubkey by asking the api endpoint for it. Have fun:
@vidister Thanks for the analysis. Indeed sounds very good!
Great to see some good news about digitalisation in Germany, too.
@vidister Welp just checked my zip code and there's a name: CLEAR. Seems like no keys for my region :(
@vidister hmmm, it seems Berlin and Braunschweig (38100) are handled by the same office, at least they have the same key and "GA number" in the API
