# Keybase

> Keybase is an end-to-end encrypted messaging, file-sharing, and public-key
> directory platform. It maps human-readable usernames to public keys and
> cryptographically verifiable social-identity proofs, and exposes a public
> read-oriented HTTP JSON API (v1.0) plus officially supported chat-bot SDKs.
> Founded by Chris Coyne and Max Krohn; acquired by Zoom in 2020.
