Ratings and reviews

5 out of 5 Worth every penny! I recommend this to anyone who is looking for a decent app with cryptographic functions and learning. Things I want to see added. 1. Full GPG integration/Multiple keys etc. 2. Ability to encrypt multiple files. 3. Option to save key is not available when you type it in only when random is pressed. 4. Option to create more certificates. Look forward to seeing further updates. Thank you for creating such a useful application.

Bêst Encryption app by a long mile, everything's explained in detail and it couldn't be easier. Our only problem was settling in on a particular cipher for our needs, as the are so many ciphers and cipher options to choose from. App is very user friendly and easy for noobs interested in the world of encryption with defaults, but doesn't assume your learning disabled either, and won't make decisions for you if you don't want it to. Bravo, authors. Re: encrypting folders, zip them first.

Downloaded to test it and it seems to be a good app but the ads are ridiculous. They are full page ads. You can't do anything without a full page ad popping up. I click RSA to see what it's about, full page ad. The ads have timers on them. You have to close the app and start over. You click on another button, full page ad. Can't even test it so goodbye app!
