I used Mailvelope for a long time and was pretty happy, but FlowCrypt really plays in another league. The fact that it automatically recognizes if contacts use PGP makes it extremely convenient to use. Moreover, the support has been amazing when I had an issue with a minor bug (now corrected). I can highly recommend it.
Fantastically easy to use.
Superb. Best pgp/ encryption app I've found. Developer is also very responsive to issues and feedback.
Finally, a simple seamless way to use PGP keys with Gmail. Love it!!
Perfect! Easy to install & works great with gmail-just what I needed!!! Thank-you FlowCrypt
easy to use and fast.
So far a great experience considering how horrible many PGP UX have been. Cant wait to see what else is to come. Trying the beta Android App, works great cant wait to see biometric security setting/PIN. Keep impressing me.
Great plugin. The dev team is super helpful. Thanks, Human!
Very easy to set up and use. Their support is also very reactive. Works when encrypting messages to other encryption suites too (e.g. GPG Tools), so it is not a closed network. Can provide your own PGP key, or generate a new one. Public keys can be downloaded as files and/or included as an email signature. Fantastic product.
So easy to set up and use and no impact on browser performance. An incredibly eloquent solution to PGP end to end encryption.
