@martinrust @alice quite frankly I don't know where that's even from considering the android.com page makes no mention of the word "evidence", though that's not to say it provides any clarity on the matter.

@martinrust @reiddragon @alice I would have thought that it meant you can prove you have the private key by signing a message back to Google with it, and then they verify by using the public key to decrypt.

@martinrust @reiddragon @alice i had been under the impression that "evidence" just meant "proof that you have access to that key" i.e. a very basic test where they send you random data, you encrypt it with your Private Key, and they verify with your Public Key. I've done no reading on this topic tho. Is that not the case then?

@Li @alice again, though, read Google's own site and that one never mentions proof of anything. The vague concept of proof of private keys is NOT what Google is saying, it's an interpretation of what google said because they made everything so vague there's no functional difference between Google's posts on the topic and a David Lynch movie: everyone kinda just understands something different and none of it is wrong because the original text technically didn't actually say anything concrete.
