Procedure
u
Obtain the CA certificates from one of the following sources.
n
A Microsoft IIS server running Microsoft Certificate Services. See the Microsoft TechNet Web site
for information on installing Microsoft IIS, issuing certificates, and distributing certificates in your
organization.
n
The public root certificate of a trusted CA. This is the most common source of a root certificate in
environments that already have a smart card infrastructure and a standardized approach to smart
card distribution and authentication.
What to do next
Add the root certificate, intermediate certificate, or both to a server truststore file.
Obtain the CA Certificate from Windows
If you have a CA-signed user certificate or a smart card that contains one, and Windows trusts the root
certificate, you can export the root certificate from Windows. If the issuer of the user certificate is an
intermediate certificate authority, you can export that certificate.
Procedure
1 If the user certificate is on a smart card, insert the smart card into the reader to add the user
certificate to your personal store.
If the user certificate does not appear in your personal store, use the reader software to export the
user certificate to a file. This file is used in Step 4 of this procedure.
2 In Internet Explorer, select Tools > Internet Options.
3 On the Content tab, click Certificates.
4 On the Personal tab, select the certificate you want to use and click View.
If the user certificate does not appear on the list, click Import to manually import it from a file. After
the certificate is imported, you can select it from the list.
5 On the Certification Path tab, select the certificate at the top of the tree and click View Certificate.
If the user certificate is signed as part of a trust hierarchy, the signing certificate might be signed by
another higher-level certificate. Select the parent certificate (the one that actually signed the user
certificate) as your root certificate. In some cases, the issuer might be an intermediate CA.
6 On the Details tab, click Copy to File.
The Certificate Export Wizard appears.
7 Click Next > Next and type a name and location for the file that you want to export.
8 Click Next to save the file as a root certificate in the specified location.
What to do next
Add the CA certificate to a server truststore file.
