Linux Poison shows you how to create and manage encrypted folder (EncFS) in Ubuntu with Cryptkeeper

EncFS creates a virtual encrypted filesystem which stores encrypted data in the rootdir directory and makes the unencrypted data visible at the mountPoint directory. The user must supply a password which is used to (indirectly) encrypt both filenames and file contents.

If EncFS is unable to find a supported filesystem at the specified rootdir, then the user will be asked if they wish to create a new encrypted filesystem at the specified location. Options will be presented to the user allowing some control over the algorithms to use. As EncFS matures, there may be an increasing number of choices.

EncFS offers several advantages over other disk encryption software simply because each file is stored individually as an encrypted file somewhere else in the host's directory tree.
