encfs – encrypted filesystem in user-space

Quoting from Wikipedia:
EncFS is a Free (GPL’ed) FUSE-based cryptographic filesystem that transparently encrypts files, using an arbitrary directory as storage for the encrypted files.

Two directories are involved in mounting an EncFS filesystem: the source directory, and the mountpoint. Each file in the mountpoint has a specific file in the source directory that corresponds to it. The file in the mountpoint provides the unencrypted view of the one in the source directory. Filenames are encrypted in the source directory.

Files are encrypted using a volume key, which is stored encrypted in the source directory. A password is used to decrypt this key.

Sounds complicated, but it’s really not. Basically what we are going to accomplish here is creating Directory that has all the files in it encrypted.
This will work on any system, this requires 3 applications if they are not already installed. fuse rlog encfs For me, it’s simply a matter of using pacman and installing them. You can use whatever package manager your distro provides or you can install from source.

My new 8,192 bit public key.

I’ve been playing with gpg again, and decided it was time to bump up my key size in order to have a key that was acceptable for encryption for the next few years. Until quantum computing kicks in, then I’ll have to double/quadruple the key size again… who knows. But for now, I think this will suffice for awhile.

Modifying gpg source code to allow 8,192 bit keys was simple to accomplish and the information is freely available on the net, so I won’t repost it here. However, if you want my new key, here it is :)
