Amazingly useful and simple, thanks for making the world of encryption within the reach of everyone!

Great extension!

Excelent GMail integration! Congratulations and thank you!
Very easy to use, and the developer is really helpfull as well! Works perfectly.
Worked perfectly in spite of my noobish-ness. ;) An excellent product.
Easy to setup and use. Encrypts messages with all recipients. Tom is on top of things.
It is so simple to set up and just works!
Awesome platform and really simple to use, but the best part was the customer service assistance I got from Tom. I was new to encrypting and he really helped every step of the way and even offered to send me the Android link when it's ready. Really amazing experience.
