FlowCrypt a. s.

Simple end-to-end encryption to secure email and attachments on Google.

🟢 FlowCrypt adds a Secure Compose button to Gmail so you can send encrypted emails and attachments using OpenPGP. It is designed for individuals, teams, and Google Workspace organizations that need private email communication without changing their Gmail workflow. 🟢 You can generate a new PGP key in a few clicks, use an existing key, send encrypted attachments, sign messages, and exchange encrypted email even with recipients who don't use FlowCrypt. 🟢 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). ✔ Sign encrypted emails to let your recipients verify that the message is from you and that the content hasn’t been modified. 🌐 Website: https://flowcrypt.com/ 📁 Source code: https://github.com/FlowCrypt/ 📚 Documentation: https://flowcrypt.com/docs/ 🧠 Knowledge Base: https://flowcrypt.com/blog/questions/ 📱 Android & iOS apps: https://flowcrypt.com/download 📩 Looking forward to your feedback!
