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.

Great for sending and receiving secure emails! Its not only important for it to be simple for the sender but this makes it super easy on the recipient too. Not clunky, just simply easy and reliable. USA review. Big 'Thank you' to the developers and their support.
FlowCrypt Browser Extension is not approved by Advanced Protection! So Google users with Advanced Protection can't use it.
Hello! when will you guys be set up with outlook? I've used flowcrypt before and it's VERY useful
When will this app be Reverified by Google ?
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?
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.
Honestly, I normally do not write review but WOW, I've tested many options (free) and all worked VERY WELL! Not sure why yours isn't working but to me... it was smooth and easy to test it out! And, yes... I've tested other 2 (no names here) and it was CUMBERSOME, geez! Great Job!
I sent a test email 50 minutes ago and it has not yet been received. Tried again and it has been 15 minutes and not received also. This is disapointing

Does not work at all, gets stuck in a Google sign in page loop, wasted of time installing and trying to fix.

I liked this extension when I used it in the past. However, it does not work with Google's Advanced Protection service. I really wish that Google would allow this app for those that are enrolled in the Advanced Protection Program. The inability to use this app under that service really irritates me.

This software is already obsolete. No support response, no update nor no severe security fix. In addition, hardcoded part is also too old, so many functions don't work. To keep your pgp/gpg providing security, this is already dead. We need other open sourse fine pgp/gpg frontend for gmail. I completely disappointed this front end of pgp/gpg. Especially, this extention breaks our pgp/gpg encryped or signed email. At this moment, we must call it non-secure ware just saying itself sesure, unfortunately this is same as malware. Do not use it.

Крутая вещь
I just recently started using , and as others have said the onboarding process is seamless so for now four stars , I will revisit after some testing. A big thanks to the dev team @ FlowCrypt.)

No undo in secure composed emails. Just started using it, there is no undo after email is sent for a certain time (seconds). would be a good feature. Thanks.

It's a nice extension but it is reserved for experts on encryption like me <: Just kidding everyone can use it and it is a really helpful extension. I send AES-256 bit encrypted files with a software like this. Yes I said software. This is like one.

Lässt sich superschnell und einfach einrichten.
Very easy to use. It loses a star because it does not yet support autocrypt, particularly sending autocrypt headers. I'd also really like to see the compose encrypted mail interface replace the regular compose mail interface (particularly when it comes to Gmail shortcuts). Since the new interface can also send mail unencrypted, I don't need both. It would make the UI cleaner.

Very pleased that I can use something like this for my small business. Thanks for helping secure our Gmail account because so many people use Gmail and it still comes off as a professional extension for emails. -JR

The UI is decent but there are some serious functional issues with it. Their (hard-coded) key server doesn't seem to find keys in the other key servers it claims to look in. Their key server and/or UI doesn't seem to handle multiple keys that match a given recipient in public key servers. There is no ability to choose one and It's unclear how it's even choosing the key it chooses to use when multiple exist. I would have assumed newest key of highest strength, or most signatures, etc. but neither of those are the case. With these key server issues, the extension is not useful for all but very narrow use-cases. I've contacted support about these issues but the only one response I got back was pretty lack-luster and my followup has gone unanswered. So TL;DR: I cannot recommend this extension.

I've been looking for a way to send encrypted emails to a loan officer and I'm so glad I found this extension. This is the answer to all my problems, easy to use and it doesn't require the other party to install it. 6 stars !!!

Muy cómodo y sencillo de utilizar.
So happy to find this. I lknow PGP for long time, but lost hope it would finally make it into Gmail. Here we are! Easy install, works great.

This extension is a PGP encryption tool that doesn't suck. It's very easy to use and also is quite secure. Tip: spread the word! If you don't do that, you won't have anyone to securely email!

Awesome way to integrate PGP into Gmail! I'm using the Android app plus the chrome extension with great results!

simple efficace merci
Thanks so much for making a free ( and very very secure; I've uploaded my own PGP key to verify ) app that helps society and Americans follow the US Constitution as intended, which helps humanity by definition!

The apps works great and when I had questions the developer answered right away. Great app and great service!
