http://www.cloudfogger.com/

Cloudfogger encrypts your data on the local device before it gets uploaded to the cloud. That guarantees that Dropbox and others never get access to the content of your files.Cloudfogger protects your privacy with 256bit AES (Advanced Encryption Standard) encryption. Cloudfogger uses transparent encryption, which makes daily use fast and simple: On the local system you still access your data as you always did – while all files are securely encrypted when they get uploaded to the cloud. Manual encryption and decryption of your files is not necessary with Cloudfogger. Cloudfogger-protected files can also be shared without sacrificing security. You can for example use your shared Dropbox folders securely together with others – without the need of giving them your Cloudfogger credentials. Also, distributing files via e-mail or USB sticks is easy with the portable Cloudfogger file format. Cloudfogger automatically detects cloud storage providers that are installed on your system. Additionally you can select any other folder on your computer that you want to protect. All files in protected folders will now be securely encrypted on your hard drive – and will only be uploaded to
your Dropbox fully protected. With Cloudfogger, you can also easily encrypt and decrypt single files via the Windows Explorer context menu. Handy when you only want to encrypt a few files because you want to take them with you on your USB pen drive. This will be added to Privacy Resources Subject Tracer™.
