Just to clarify: CryptoAPI is a set of encryption functions available in
Windows that expose standard cryptographic algorithms. .Net encryption
routines offer a higher level interface to CryptoAPI. The encryption in
SQL Server 2005 is also based on CryptoAPI. Any Windows application can
use these routines. For a list of the algorithms available through
CryptoAPI, you can take a look at:

Yes, that could be used. (I'm not sure if it's status is still considered
secure...)

What about Microsoft's Crypto API?

Very limited.

If using a .NET applicaiton, there is a rich encryption library that
could be used at the application level to encrypt data before it is
stored in the server, and decrypt it after if is retreived.

And there are several third party 'Add-ins' to allow encryption via
extended procedures.

A very crude 'hiding (and generally ineffective) scheme would be to use
one of the checksum() functions and do a one-way process. You couldn't
'decrypt' it but you could use a comparison to verify if an input value
matches.

As far as I know, the application level method is the only way to keep
a determined DBA (or Admin) from being able to access the encrypted
data AND the means to decrypt it. (But then, the question is "Is that a
wise decision?, Are you feeling lucky? Go ahead, make my ..."

What is the recommended way to store data in SQL Server 2000 encrypted
so not even DBA can see the values? I know SQL 2005 has encryption at
the row level, but what are my options in SQL 2000?

Thank you,

Steve
