>>>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.

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.

You can use different block ciphers with wwEncryption as well.
