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!
works perfectly with my gmail workflow on mobile and chrome browser! THX
Relativity easy to use and very convenient.
I like it!
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!
