For those who may not know, the "Mike C" above is actually the amazing Michael Coles an expert in this area (see here: http://www.amazon.com/Expert-SQL-Server-2008-Encryption/dp/1430224649) and a great guy to boot. I know that Michael is a humble person and doesn't normally promote himself, however, I thought it important that the OP know that between Gail, Sarab and now Mike, you're getting some of the best help in existence.
