I have a single file (Openoffice spreadsheet) that I have kept on a
3.5 floppy disc that I would like to put on my Ubuntu linux system
(~/) for convenience. It contains sensitive financial information (my
investment data, account info, passwords). Any thoughts on the
easiest and yet secure method of single file encryption? Or would it
be best to just continue to keep it on the floppy and access as needed?

I'm sure there are several aps that can encrypt the file. I'm only
familiar with GPG (and not familiar with Ubuntu).

Do a "man gpg" and see what happens. If GPG is not available then
install it. It can be used from the command line or there are various
GUI's available depending on your "desk top".

Try your question in alt.security.pgp.

I would recommend GnuPG. If you don't already have a keypair, create one,
and then you just need to do a:

gpg --encrypt FILENAME
shred --remove FILENAME

And then keep FILENAME.gpg anywhere on your filesystem. When you need to
use it again, do a:

gpg FILENAME

enter the passphrase for your key when prompted. You can then use the file
as normal. Once you are done making changes, save the file and exit the app
you are using, then run the two commands up above to re-encrypt the file.

Oh, shred is a more secure way of deleting a file. It overwrites that
section of the disk 7 times, to make sure that the data can't be recovered.

I really like ccrypt, it's easy, and with the GUI integration Script, you can
add enties to the right click menu, you can also do it CLI if you wish/must.

Ccrypt
http://ccrypt.sourceforge.net/

GUI script

Although the GUI script page seems to be down at the moment, it may or may
not be only a temp thing ?

GPG is really good for that. It supports many encryption algos and is a
stable and mature software, which is very important when it comes to
securing sensitive data.
