Keybase is a free, open source security app. It's also a public directory of people.
The Keybase app helps you perform cryptographically-secure operations with people you know on the Internet: chatting, file sharing, even publishing public documents. It's all easier and safer with Keybase.
The Keybase app is improving every day. To get started, download the app, create an account, and connect one or more of your social identities.

Welcome to Keybase
Keybase connects your social identities (say, your Twitter, Facebook, or Reddit account) to your public keys. Public key cryptography allows encrypted conversations, digital signatures, and other sweet, savory security. It is magical, but confusing. Keybase tries to make it easier.
Our mobile app (with chat and file sharing) is almost ready. In the meantime, you can create a web account to start connecting your social id's.
The desktop app is available on macOS, Windows, and Linux: download it here.
