I don't think you want one-way encryption, that would mean you can't
unencrypt it!

What about the usual functions for encrypting strings in PHP? Couldn't
you encrypt the file as a string and output that? Or did you want the
file to request a password when it was opened? What about a
password-protected compressed archive file?
