Is there any free or inexpensive OS X app that will allow me to encrypt
some files, take them on a CD or a USB stick to a Windows PC, and then
open them on the PC, without having to install any additional
decrypting software on the PC? Perhaps something like an encrypted .zip
creator for the Mac?

Thanks.

I've heard of but never tried TrueCrypt (http://www.truecrypt.org/).
but from what I've heard, it's very good. See Security now
(http://www.grc.com/securitynow.htm) episode 133 for lots of details
and analysis. There are alternatives (Compusec? and IronKey) are
talked about in other episodes, later episodes will have more details.
There are also transcripts available from the same site - there is a
lot of detail which can get very confusing.

Aren't there PGP applications that do that?

I think the mac's unix zip (the one you activate from the terminal) does
encryption. (I used it once to decrypt a zip)

Cool, thanks. It looks like zip -e should do what I want. But I am
having a problem with it. I did this to zip the contents of my
Desktop folder:

cd ~/Desktop
zip -e stuff *

It appeared to create the encrypted archive properly. But when I try to
open it in the Mac, Archive Utility launches, and displays this error
message:

'Unable to unarchive "stuff.zip" into "Desktop". (Error 1 - Operation
not permitted.)'

What am I doing wrong? I haven't even tried opening it in Windows yet.
