Ah, a fellow Delphi programmer...! I noticed in another context that Mercury includes the CryptLib library, and that there is a Delphi interface for it here: http://cryptlib.sogot.de/delphi.html
Not sure if that could be of any use for you, but it would at least be independant of any Microsoft version problems.
It's actually delivered with Pegasus Mail as well, but I don't want to use it for several reasons:
1. I'm already using the CryptoAPI in my PGP extension, so I'm a bit familiar with it.
2. CryptLib doesn't provide any user interface and especially no convenient key/certificate management tools.
3. People switching from any kind of "Windows Mail" may already be accustomed to using the built-in user interface and "certificate store".
4. There is a CAPICOM interface for Delphi as well (you need to use the TLIBIMP tool to extract it), so that's not the main issue (except for a couple of fixes required), it's just getting accustomed to new interfaces no matter which one. And like I said, CAPICOM solves the version issues.
