Cryptography on Windows

Is there a nice cryptography library for Windows which I'll be able to compile without mingw/cygwin?
CryptoAPI is dildos because you have to dick around with KeyContainers and ServiceProviders and other ENTERPRISE bullshit.

But it doesn't work with XP, does it? I can't use it, then.

I didn't actually look closely into the CryptoAPI documentation; but you need to install certificates and key stores and shit like that, right? I shouldn't do that if I'm writing an application which should make as few changes to the system as possible.
