I think they are refering to encrypting the database. They have SQL Server 2000 and I have a test server with SQL Server 2005. I need something that can work in these two versions of SQL server.
I know there are many ecryption types. I really dont care which one I use. The only requisite is that it has to be 128 bits.
What I dont know if the encryption must be handled by the database itself or by PHP. For example, maybe I can do a function in PHP that encrypts a string using AES and then storing that in a binary field in the database. Then retrieve it and decrypt it using PHP. I dont know if this is standard procedure, or there is something that can handle encryption by the database itself. But then I dont know if the queries have to change, and this is why I dont know if I can use ADODB abstraction layer to handle those special queries.
