>We are planning to encrypt the passwords and Credit Card Numbers here, and want to see what is available.I would suggest the Windows CryptoAPI. This gives you professional-level encryption routines.

If you have VFP 7.0, there is a class in the FFC under Utilities (_crypt.vcx) that makes it very easy to use.
