Cipher

Cipher is an easy to use simple solution for securing your data, be it documents, pictures, presentations or corporate secrets. Secure the data on your device, on SkyDrive or in your cloud. Did I mention easy to use, because it doesn't get any simpler to encrypt your info. Simple, clean Windows 8 interface.

Its a powerful lock.Well worth my money.

After a file is encrypted and you have to close the app all the way down. Otherwise the passwords are still locked into the prompt and any file can be opened. It'd be nice to be able to encrypt a whole directory too. Otherwise it does what it says pretty fast too.
