Hi, Theo.
Yes, you have to use a third party product.
I used NetLib (www.netlib.com) in the past. It wasn't so expensive then, but I think it is now around $1000. Also, many time ago it used to be a bigger product, but now is separated in different Kits. The Encryption one is which cost 'round a grand. I can be wrong, check the site.

I know other people use Cryptor, and it provides basically the same features when used from a VFP app. It is around $299 at hallogram (www.hallogram.com).

NetLib (and as far as I know Cryptor, too), just intercept the read and write operations made by your app, so data is never decrypted, except when your app is accessing it. No matter how many users are using your app, if someone else tries to open a table right from VFP or via ODBC, she just gets trash.

The setup is VERY simple. You have to encrypt your data (generally a five line PRG) with a password, and then call a function (with the same password) in your app startup that basically enables encryption/decryption troughout the rest of the application. So you don't have to make any chages except for these little things.

Hope this helps.
