I had some self inflicted troubles configuring this extension (because I wholly failed to follow the directions) for which I contacted the developer. He was amazingly pleasant and helped me get even my odd issues resolved. As a long time GPG user, this brings the functionality of something like Enigmail to the ease of use and ubiquity of Chrome. Thanks Tom!
This is exactly what I've needed to complete, both, my Google and PGP ecosystems! Great fast support directly from Tom. (As a fellow "small-time" developer, I can totally relate!) I look forward to all the great features to come in the future!
Great, and great support
Awesome extension, quick response from developer!
Installed app about one month ago. Very pleased. Thanks Tom
Easy as water to use, the setup is quick takes few seconds and you are ready to go. The App, in general, was made to be super user-friendly, no need to change any settings, even though the settings GUI is well made. The App can send encrypted messages and attachments to most applications the support PGP and even users that don't have PGP. The best part is the incredible fast support from Tom, the lead developer. Thanks a lot Tom for making this amazing App, I had a blast using it!
The best solution at this moment: open source, balanced freemium, pretty good UI/UX. Wish you good luck!
Finally PGP for the masses! I hope Google will not try to block it in some way.
Seamless integration with Gmail. I'm not very tech savvy but need to send secure encrypted messages with attachments. CryptUp is the most user friendly app of its kind that I found - there's really nothing that compares for ease of use. The developer is highly responsive and has big plans for future development of the app. I look forward to seeing how this evolves.
We've been looking for something like this for a while. Initially we had a a compatibility issue with enigmail, but the issue was fixed and released a few days after encountering it and it now works seamlessly. The creator, Tom, has been very responsive.
