BoxCryptor: Easy, On-the-fly Dropbox Encryption


Cloud file storage service Dropbox is a long-time favorite here at WWD — it provides a quick and easy way to store files in the cloud, sync them between different machines and share large files. However, although Dropbox encrypts your data, to be completely sure that your data is secure, you need to encrypt it yourself. Up until now that’s been a fairly laborious process. Enter BoxCryptor, a Windows-only (s msft) tool that can encrypt and decrypt files on your Dropbox account in a completely seamless fashion.

After installation, you’ll need to provide a password to encrypt your files with and a directory to save the encrypted files in. BoxCryptor then acts as a virtual harddisk, encrypting and decrypting data in real-time. Save a file to the virtual disk, and BoxCryptor automatically encrypts it and stores it in the directory you specified. Retrieving a file is just as seamless.

BoxCryptor is currently free and requires the .NET Framework 2.0 to run. It’s a really easy-to-use tool, but you should note that the version that can currently be downloaded is only an alpha that will fall into read-only mode on 31st March 2011; the author recommends not using it for production purposes just yet.

Is there a cross platform alternative?

I’m interested in some form of transparent encryption… but need to support both Windows and Linux. I would not want to encrypt all my files, just a specific folder. I rely on Dropbox on a daily basis… it really is a great service! I take for granted how easy it is to get to my files on my PC, notebook, android phone, and iPod.

If someone reading this doesn’t already have a dropbox account… give it a try using my referral link.

You’ll get an additional 250 MB and so will I :-)
It’s just one of those great it “just works” services.

Added encryption like this will protect your data if your Dropbox account is compromised. Additionally, Dropbox theoretically has access to your data because it holds the keys. Note that I’m not saying that Dropbox (or any other cloud storage provider) is untrustworthy, but particularly for users using Dropbox to store confidential IP this added encryption is an easy way to keep the data secure.

It’s similar, but BoxCryptor is easier to use IMO as there’s no mounting/unmounting to do. BoxCryptor is Windows-only, though.
