Is it possible to use a symmetric cipher with org-crypt.el? I'd really
like to encrypt certain outlines and encode/decode them on several
machines without worrying about managing public/private keys.
I can see how using public key crypto might be benefecial when sharing
files between several parties, but for the case where a single user
simply wants to synchronise org files between various machines (and
never store/transmit sensitive data unencrypted) then a symmetric cipher
seems preferable due to its lower overhead.
Has anyone done this?

Not that I know o, but I think, starting with org-crypt this should be
relatively straight forward.
There must be someone else around here who can take on this task, right?

Hi Rick,
I don't think anyone has done this, but I would certainly welcome
someone taking up org-crypt.el, adding different options like you
suggest. I'd be happy to work out the UI, but I do not know anything
about encryption or Emacs packages supporting it.

Thanks Carsten, I know a tiny bit about encryption, but I'm no guru. I
took a quick look at easypg which org-crypt appears to use, and being a
frontend to GnuPG it seems to support the use of symetric keys.
I'm convinced that it should be a trivial job, but I'm not familiar
enough with any of the packages to know precisely what needs done.
If I find some more time, in the next few weeks, I might take another look.
