Description
Hello, keybase is e2e, which means the server (api.keybase.io) should not know anything about msgs between peers; all messages go through the server, so i have a couple of questions:
-
What is the passphrase used for?
-
Is connection between the client-server using a stream cipher or a block cipher? (which one?)
-
Are you using Diffie-Hellman to exchange new keys for encryption in each session against the client-server?
-
How is e2e ensured in the app?
thanks for your time, i'm using keybase :-) great work!
