Keybase Andrey Petrov ,Chris Coyne מאת

Keybase for Firefox is an official Keybase extension for composing ENCRYPTED messages to any Twitter, Facebook, Reddit, HackerNews, or Github user, from the convenience of your browser. It's an easier chat, and it's end-to-end encrypted.

This works even if they have yet to join Keybase. The quick summary:

• Everyone with a social network account has a Keybase inbox, *even before they join Keybase*
• You don't need to know the recipient's email address or phone number or Keybase username—just a social media username is enough
• No one (at Keybase or the social networks) can read your private exchanges
• Look for the "Keybase Chat" button on profiles around the web
• Toggle specific features in the extension options

At no point in Keybase's protocol does Keybase ever have the keys necessary to read your messages. This is end-to-end encryption, powered by the convenience of public social media usernames.

Keybase is open source, and so is this extension:
• https://github.com/keybase/client

You can find the recent changes for the extension in the history of the "browser" directory.
