FlowCrypt: Encrypt Gmail with PGP

Simple end-to-end encryption to secure email and attachments on Google. 🟢 A simple end-to-end encryption to secure your emails and attachments on Google, including Google Workspace, Business, and Enterprise using OpenPGP. 🟢 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. 🟢 Adds a Secure Compose button to Gmail, allowing you to send private PGP-encrypted emails when you choose to. 🟢 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). ✔ Sign encrypted emails to let your recipients verify that the message is from you and that the content hasn’t been modified. 📩 Looking forward to your feedback!
