Encryptr is one of the first “in production” applications built on top of Crypton. Encryptr can store short pieces of text like passwords, credit card numbers and other random pieces of information privately, in the cloud. Since it uses Crypton, all data that is saved to the server is encrypted first, making even a server compromise an exercise in futility for the attacker.
A key feature is that you can run Encryptr on your phone as well as your desktop and all data is available in each place immediately. Have a look:
The author of Encryptr, my colleague Tommy @therealdevgeeks, has recently blogged about building Encryptr. I hope you give it a try and send him feedback through the Github project page.
