Linux shared-secret encryption for burning CD ROM

["sun sadm" <sunsadm () gmail com>]

Hi colleague

I am searching for a strong, password-protected encryption of
directories and files. I will use it for burning CD ROMs. Don't wish
to us async encryption with certificates. The decryption should work
on every Linux and UNIX like OS without installing additional
software.

What would you do?
