Product summary

🟢 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:

E2E encryption in the easiest possible way and all the goodness of PGP. Fast acting development team, great support. Looking forward to the mobile solutions and I am thinking about supporting this project by getting the upgrade for a monthly free. Well done so far.

it's pretty great. simple and intuitive. there were a couple of things that i would like added, such as signing (by default), PK setting, etc. i emailed support and they were very quick and helpful.

CryptUp is a great tool. It makes it easy to use encryption even for private mails without a PKI structure. Thank you very much!

I am a cyber security incident response specialist. And given GMail currently does not provide built in E2E encryption, CryptUp couldn't be simpler and it just works. Highly recommend.
