Welcome to Keybase

Keybase is a new and free security app for mobile phones and computers. For the geeks among us: it's open source and powered by public-key cryptography.

Keybase is for anyone. Imagine a Slack for the whole world, except end-to-end encrypted across all your devices. Or a Team Dropbox where the server can't leak your files or be hacked.

Download the app to join.
