Summary

Analyze keywords

🟢 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).

Trying to import my PGP keys, i got the error "This key is not supported by FlowCrypt yet. Please write us at [email protected] to add support soon. (decrypt error: Error: Encrypted private key is authenticated using an insecure two-byte hash)"". What now? Can I update this authentication hash somehow?

Hello, I hope you're having a splendid day! I am currently seeking opportunities to expand my business operations by investing in extensions with a significant user base, beginning from 50,000 users and up. No matter if your extension has a modest user base or counts its users in the millions, I am interested and ready to negotiate a purchase. If you are in possession of such an extension and looking to turn it into a profit, please consider reaching out to me. We can discuss the price and proceed with a transparent and secure transaction through a trusted escrow service based in the United States. It's great that Google allows the transfer of extension ownership between accounts, so your Google account ownership will remain intact. If you have any needs, please contact us via the following contacts Whatsapp: +1 (248) 896‑8035 Telegram: t.me/harryysandersonn

works well - when it works. first test email went through right away. 2nd never arrived. 3rd was received ok, 4th and 5th havent arrived after 3 minutes. so... if you use this you will have to check using another method to make sure the encrypted email arrived at your destinstion -which makes it not very much use. sorry, I would have liked to use it but its not reliable enough.

Risk impact

FlowCrypt: Encrypt Gmail with PGP is very risky to use and it requires a lot of sensitive permissions. Avoid installing this extension unless you absolutely trust this publisher.
