Encrypting DBFs in Windows Vista

I had used Cryptor 4 to encrypt DBFs but this one doesnt work in Windows
Vista. Cryptor 5 can run here but I found many messages of problems with
this version.

Netlib which I used before is now very expensive.

What can I use now to encrypt DBFs in Vista?

Thanks.

Mind to the post error messages from both 4 and 5?

I had never heard of Cryptor until now. It sounds like something I could
really use, if it worked.

What has been your experience with it? What are the error messages you're
getting?

I see on Hallogram that "Cryptor 5.0 currently does not support Windows
Vista". Too bad.


What is it like to use? I mean, what do you have to do in your programs to
use it? Maybe I should write something like that myself.

Thanks Man-wai and Paul:

I use Cryptor 4 to encrypt critical data-several DBFs. I had written an app
in which creating DBFs involved a lot of work and time. These files are as
important as the source code. So I decided protect them.

In Cryptor, DBF files remain encrypted all time in your disk and when your
program is executing they are decoded to memory. It uses a password that
your program have internally. So no one can open such files out of your
program because of the message "Its not a table"

The error message from version 4 in Vista is irrelevant. It doesnt work here
at all. Some people say version 5 works in Vista, but with troubles as
registering the COM object with regsver32 . I had not used this version
until now.

Maybe you have some different idea to protect data. Share it to me please.

The main alternative that I know of would be a different back end, like SQL
Server. But encryption would be enough for my current application, if only
it would work on Vista.
