GPG would probably work well. You can encryt files symmetrically and
put a passphrase on the file. Public Key encryption could work also, as
long as you have a decent passphrase on your private key. If your
private key is passphraseless and someone gets physical access to your
machine they'll have not much problem decrypting your file. GPG also
had other useful applications, such as signing emails and various files.
