I've been looking into encfs as a solution to encrypt my personal data. However I want to access this data both on Linux and Windows on different machines (synced through Dropbox). So far all Google searches have brought up pages which specify that there is no Windows client that reads encfs.
Can it be done?
There's also Safe. It's fully compatible with EncFS and works on Windows and Mac OS X.
I recently released a new project called EncFSMP, a multiplatform EncFS implementation. It works on Windows and Mac OS X. It is open source, however it contains a closed-source component for the file system access. Since it is based on the same source code as the Linux implementation, it is 100% compatible.
Note: this answer was written a long time ago and no longer applies to modern Windows version and currently supported software.
Since encfs is built on top of fuse, the obvious way would be to port it to a fuse driver for Windows. Apparently the two most likely possibilities are Dokan and Eldos Callback Filesystem, though neither currently advertises encfs support.
In the meantime, an alternative would be to run a tiny Linux file server inside a virtual machine or with Colinux.
An encrypted filesystem that is supported by both Windows and Linux is Truecrypt. Synchronization via Dropbox is likely to be a lot more expensive than with encfs, but it might still be doable if your files are small enough.
You might take a look at http://boxcryptor.com/ which uses Dokan to implement a encfs compatible file system and integrates with Dropbox. It's still in early beta, but really worth a look.
I just installed encfs4win on a Win7 box - and it works. Truecrypt worked for a while, then wouldn't open the file from one machine - while still opening it from another. Flaky. I like that encfs is open source and more likely to be around in 5-10 years (imo).
