Hi to all:
    
      I implemented my own CSP which has my own encryption algrithum . I try
to send S/MIME email use my own CSP and my algrithum in Outlook express.
Certificates in MY store are set KEY_PROV_INFO to point to my CSP.

     But,
     1. I can't select my algrithum in Outlook Express's
Tool|account|security, the default algrithum shows

     2. Outlook Express uses the default CSP to verity the incoming email
signature and encrypt the outgoing email, but I want to use my own CSP.

     I want to know how to resolve my problem?

 best regards
