Excellent software that just works. It makes using PGP with Gmail actually practical. I actually had a problem where it broke, and one of the developers replied within a few minutes and suggested I reinstall. Very attentive support for something that is free.
Cool product, love the gmail integration, which makes it super easy to use. Also particularly love the ability to send people to a page where they can send me secure messages, even if they only have their mobile with them :D
Easy to use, quick to setup.
Easy to use, works great. Glad to have PGP for Gmail.
awesome... an excellent balance between security and convenience. fantastic, quick support, even for the free version. thanks very much!
1. Great works. Important features work very well. 2. A few defects about ready-to-sign/encrypt mail editing on Gmail. All the text editing features (like font size, typesetting, insert pictures, ... etc) are gone. When I want to reply with quotation it is not convenient this way. 3. Switching encrypt/original view would sometimes keep the mail page there, couldn't do anything. I need to reload the page to make it work again. Generally speaking one of my dream extensions. I appreciate the developers' work very much! Thank you!
Top App. Perfekte integration in GMAIL. Klar, Übersichtlich, leicht verständlich und kein zusätzliches Fachwissen für die Bedienung nötig. Vielen Dank für diese App, eine Bereicherung für die Welt.
After various paid softwares for email encryption this one tops it! Highly recommended.
Fantastic, simple tool
Facile d'utilisation. Support super avec human
