I use EncFS to encrypt my files. So far, I've been using the installer provided by BoxCryptor.
It packs EncFS 1.7.4, MacFuse and MacFusion in one installer and works nicely on Mountain Lion. But MacFuse is not actively developed and most people might replace it with Fuse for OS X or something similar.
Are there other packaged installers for EncFS? Or do you always compile EncFS from source? If so, is there a tutorial on how to compile?
