Hi Albert,

>>I have started testing using an AES encryption/decryption class that is accessed through a dot-net bridge (wwClient tools). It works but do not know which AES is it using - AES256 or AES128 etc.

Unless there's reason not to, you might be better off with the very good vfpencryption.fll which is freeware from Craig Boyd/Sweet Potato software. It's a standard VFP fll with loads of encryption options including AES. It allows you to specify not just AES bit level, but also Block Cipher mode. For years most AES implementations defaulted to ECB for block cipher, but this is no longer regarded as secure with some state entities now disallowing EBC in their apps. Vfpencryption does default to ECB but this is easily overridden to one of the other block ciphers.

The other option would be VFP C++ Compiler that allows you to bake AES-256 right into your app, with no external libraries required. There's actually an example of this in the demo installset and hopefully there will be time to go over this in the upcoming Foxfest session on VFP C++ Compiler if you're attending. - J
