The best/easiest solution now is to use CAPICOM 2 functionality:
   http://www.microsoft.com/downloads/release.asp?ReleaseID=44155
(unless you have very unusual requirements, in which case you may
 need to use capi directly).

There are excellent samples in the CAPICOM 2 download for:
  asp, c#, C++, html, vb, vbs

The CAPICOM 2 install is rather small :-) and is supported on
 Win98 - XP (and also the 2.0.0.1 version seems to work in most
cases on Win95).
