I've used cfs a few times for things like this.  From memory:

  $ cmkdir foo
  <enter passphrase>
  $ cattach foo bar
  <passphrase>
  $ ls -l /crypt/bar
  $ cdetatch bar

No special privileges needed to use it.  It uses nfs tricks to make
your encrypted directory (foo) appear unencrypted in /crypt/bar.
While it's mounted, only the owning user can see that directory.  If
foo is not attached, you can backup the encrypted directory as is, and
restore it and remount it somewhere else.

It's in debian as cfs (of course).
