Research conducted by Christopher Soghoian demonstrated that Dropbox lacks a security model that genuinely protects user data. As a consequence, while Dropbox is a convenient service it isn’t one that can really be trusted. Regardless, individuals around the world do, and will, continue to use the service.
Recognizing the user-constrains around cloud file-storage solutions, BoxCryptor has provided the tools to encrypt files before they are sent to Dropbox. This lets users rely on Dropbox for convenient storage while also reducing their risk profiles. All in all, it’s a win-win for the consumer.
The instructions are for OS X, Leopard, Snow Leopard, and Lion, and are relatively easy to follow. If you want to secure yourself a little bit better than you likely are right now you’d be well served to set up automatic encryption now. As an added bonus, the instructions will let you also choose Microsoft’s or Google’s cloud services so long as you point the “EncFS Raw Path” to the file path of these other services (don’t worry: it’ll be super clear what that refers to as you go through the instructions!).
