I'm not trying to produce a high-security system, just something which
deters the casual user from downloading PDFs that members of the group
have paid their membership fee to receive. I doubt if anyone wants to
go to all the trouble of decrypting a PDF file in order to avoid paying
£7.50

I am a bit worried by your statement that the decryption code is in
plain sight, how can that be protected better than it already is? The
filename in the GET of the link url is also encrypted (very crudely) so,
although it is in plain view, it wouldn't lead the hacker directly to
the encrypted PDF file.

That 'someone' would have to be a member and they could equally well
send their password to a friend. There is a download log which should
alert me if something untoward is happening through the password system.

I agree it isn't suitable for a high security website, it is just making
the best of a "Topsy".
