Usable Encrypted Email


Confidante is a research project, which we have released for beta-testing and community evaluation. Though Confidante aims to provide the security properties described below, this beta version may contain bugs or other errors.

Please use Confidante only at your own risk.

And please give us feedback!

Confidante is an end-to-end encrypted email client. Our goal in building Confidante was to provide strong security properties and make it easy to use. We tested the first version of Confidante with journalists and lawyers (read the research paper here), and now we’d like you to try it out and help us improve it!

Confidante is built on top of Gmail and Keybase. It uses your Gmail account to send and receive messages, and uses Keybase to store your private keys and look up public keys. Emails are automatically encrypted and decrypted in the Confidante client; neither Gmail nor Confidante’s servers can access the unencrypted versions of your emails.
