Keybase

About Keybase

Keybase provides end-to-end encrypted messaging and secure file sharing across multiple platforms, enabling private chats and encrypted documents for individuals, families, teams, and organizations. It relies on public key cryptography to ensure confidentiality, so even the service operators cannot read users’ conversations. The project supports macOS, Windows, Linux, iOS, and Android, and emphasizes cross-device access and identity verification for communities and open networks.
