Table Encryption

[Martin]

Hi all,

I am looking to send a VFP application to someone that has several lookup
tables within it.

I dont want people being able to access and\or view the data.

Is there a way of encrpyting the data? Or are there better suggestions.

I am currently using VFP6 - is there something that upgrading to VFP7 would
help me with.

Many thanks

Martin

Martin,
One of the easiest and most secure is Cryptor IV by Xitech
(http://www.xitech-europe.co.uk/ ), but you do have to pay to use it. They
have a demo version to show how easy it is to implement, and in my testing,
there was very little overhead introduced on all but the largest tables.
I've used different versions in custom apps under both FPW and VFP.

NetLib also has Encryptionizer (http://www.netlib.com), but I've never used
it.

One freeware solution is the CryptPak by Milan Kosina
(http://milan.jikos.cz/). Another is CIPHER50.FLL based on work by Tom
Rettig and available at the UT (http://www.universalthread.com/ ) in the
Download area.

While VFP 7.0 has a Crypto API component in the Foundation Classes (I
believe it uses the MS API encryption), and Database Events that can make
the timing for encryption/decryption easier, it doesn't have anything
"built-in".
