If you can just unencrypt and re-encrypt whenever necessary, use gnupg (with the --symmetric option if you don't want to deal with keys) or somesuch. Do be careful about temporary files, but this can be made quite convenient (consider e.g. http://www.vim.org/scripts/script.php?script_id=661). Otherwise, you may consider the old and crufty security/cfs port; it may be cross-platform. Joachim
