how about something like this:

you want to move file.zip with .exe files in it and your mail provider
dont like it.

pgp -ea file.zip

It'll ask for a passphrase and produce 'file.zip.pgp'
rename it to 'file.jpg' and email it.
then on the other end, save the 'file.jpg'
rename it to 'file.zip.pgp'

pgp -decrypt file.zip.pgp

it asks for the passphrase
and you have the original file back

sounds like a lot, not hard to write a batch file to handle most of it
and this would work even with pgp262 which would fit on a floppy.

will also work with gpg (command line differs some) and real easy with
full gui modern pgp
