Keybase

Keybase is a secure messaging and file-sharing service built on public key cryptography, designed so that chats and stored files remain private. It supports one-to-one conversations, teams for groups such as families, roommates, clubs, and work groups, and encrypted storage for photos, videos, and documents.

Features include team creation, encrypted file storage, links to public identities on platforms such as Twitter and Reddit, and messages that can be set to expire. Keybase is available on multiple platforms and can be reached through Tor.

The service is aimed at both personal and work use, with no pricing or plan details indicated on the page.
