>>>I need to implement in my VFP application being converted to SQL Server backend a Password feature. Currently in the VFP application I have a table MyPasswords.dbf that has (simplified) two column USER_NAME (C(20)) PASS_STR (C(200)). The PASS_STR contains a string like this “YNYNNNY” (just bunch of Y and N) encrypted using a very basic algorithm (which I created so it can be cracked in about 20 seconds <g>). But the application does not need much of security so it works.
>>>I can basically duplicate the same approach with a SQL Server table but before I do I thought I would ask if SQL Server has a simple (emphasize SIMPLE) way to encrypt a table and un-encrypt it in VFP application?
