FlowCrypt is a tool that makes email encryption simple.

It integrates directly with Gmail, but also supports Outlook, Yahoo, and other email services, as well as mobile devices. It uses PGP encryption to keep your emails secure.

FlowCrypt works like a locked safe with two doors: the front door faces the public so anyone can put a message in, and the back door faces only you so only you can open it.

You encrypt messages using the recipient’s front door, and only they can open them through their back door. You can also digitally sign messages to prove they really came from you.

For recipients who don’t have a public key, FlowCrypt offers a password-protected option, allowing secure messages to be sent and opened with a shared password.
