This is interesting, and I am super glad that you are here, haha. I am about to (in 2 hours) give a presentation on keybase.io for a MS-level cryptography course. I like all of the features, but I was curious what the primary goal was.
I see a lot of people mentioning the encryption tools (which are awesome and easy-to-use); however, I cannot help but think that keybase.io is really about identity proofs and signing. Would you say that this is the case?
If so, are there any plans to, say, add driver's licenses, passports, or other documents to a user's signature chain? There are some countries which actually give citizens public/private keys for cryptographic purposes like voting, etc.? I ask about this specifically because my professor is Josh Benaloh (author of the Benaloh cryptosystem [https://en.wikipedia.org/wiki/Benaloh_cryptosystem]), and one of his major passions is voting and identity proofs for internet users.
Thanks for joining in, by the way!
Bonus question if you have time: any thoughts about forward secrecy as part of the encrpytion stack in keybase.io?
