Hi Rodd,

The VFP _crypto class is a wrapper around the Windows Cryptographic API. It uses whatever level of encryption your particular version of the operating system has. It works quite well but requries some knowledge of how Windows encryption works. Depending on your needs, you might look at CAPICOM, a COM component available for download from MS. There is quite a bit of info on it in the security section of the MSDN library. I have used CAPICOM with VFP without any problems. HTH
