Here is something to consider regarding the FFC class library _crypt..
We have successfully used this in the past for one of our clients, who is still using it today. However, we just very recently tried to implement it for another client and have had consistent problems with certain users on their network getting garbled results. It seems to be related to what version of Windows the user is running (although this is not completely confirmed), but a couple of particular users always end up encrypting data which is not able to be decrypted by any of the other users.
We have stopped using the _crypt library for that client, and will likely be using the vfpencryption.fll utility instead, or something else.
We are not exactly sure what the problem is with _crypt, but since researching this matter, we have found a lot of online bug reports from others as well.
The library is easy to work with and I imagine it would always work on any one particular computer, but it becomes a real mess when different computers end up with different encrypted results.

Thanks. I saw that out there somewhere; I'll be checking it out.
I have also learned that there is a FoxPro FFC classlib named _crypt.vcx that shippied with VFP 7 and newer. Si I will be checking into this one too.
I have used vfpencryption.fll with good success and it is free.

Rick - I'm wanting to encrypt a password before I save it to a DBF table, and un-encrypt when I read it back out of the table. I'm creating a basic app login strategy (client app, not web).
Do any of your Client Tools classes provided this feature? Or can you recommend anything?
I'd prefer a pure FoxPro solution if possible, but I could use wwDotNetBride if I have to.
