I recently set up a new system with WinXP Pro SP2 and discovered that
algorithms under Outlook didn't include SHA1 or 3DES... which I'm required to
use under for a customer. I'm pretty sure the set of suported algorithms is
from the CryptoAPI, and so the theory is that I can install additional CSPs.
I recall doing this under prior versions of Windows with the "High Encryption
Pack". However, I can't seem to find any MS download or product that will do
this for XP.

I found a list of the MS CSPs defined for the CryptoAPI at the following:

Any suggestions or pointers?
