🟢 FlowCrypt lets you use PGP encryption by generating a private and public key. It uses the recipient’s public key to encrypt the email, and only the recipient’s private key can decrypt the message and reveal its content.

🟢 We update the extension regularly (see the "Updated" field to the right).

FlowCrypt allows you to: ✔ Set up the extension in just a few clicks. ✔ Generate private keys using the ECC and RSA (up to 4096-bit) algorithms. ✔ Use FlowCrypt’s own Attester public key server. ✔ Send and receive encrypted emails and attachments (up to 25MB, with previewing functionality) to anyone. ✔ Send and receive encrypted emails directly or through Encrypted Contact Page. ✔ Send password-protected emails to the recipient who doesn’t have any OpenPGP software (as well as receive such emails).
