Re: Encrypt a file to prevent unwanted viewers?

This is what I would like to do:

Send a file through email so only that person can read it.

PGP or GPG will do that with public/private keys, if you can get that
person to learn how to use those, generate a pub/private key pair, and
send you his public key so you can encrypt the message with his public
key.

Only he, with his private key, could decrypt that message.

I want to prevent him from sending it to anyone. For his eyes only.

Now you've got a challenge.

Is there an encryption program that can do that? I don't want a
password or anything like that. I want the receiver to not have to do
anything, but make it so if he forwards the email to someone else they
are not able to read it.


Some mail clients like Lotus Notes have a "prevent forwarding" feature
that you can flag on messages. You both need to be using notes
though, and the feature is circumventable.

The file that I am sending through email is .doc. I was think of
sending PDF's though.

I'm afraid short of having a face to face meeting and patting them
down for a hidden recorder or wire, I'm not sure you can achieve what
you seek in a fool proof way.
