Protecting directory trees with gpgdir
gpgdir uses GNU Privacy Guard (GnuPG) to encrypt and decrypt files or a directory tree. You could accomplish the same objective by tarring the filesystem up and then encrypting the tar.gz file with GnuPG, but then you would still have to shred or wipe every file in the original directory tree. With gpgdir the whole tree is encrypted in one command.
The program's sources as well as i386 and x64_64 RPM files are available on the gpgdir download page. Packages are not available from the standard Ubuntu, openSUSE, or Fedora repositories.
