You should remove your Demo CA's self-signed certificate from your Web browser, both to avoid confusion in real use of your browser, and to enable this tutorial to be run again if required.
- In your browser, go to the options where you manage certificates.
- Internet Explorer, click
Tools >
Internet Options >
Content >
Certificates. Then go to the
Trusted Root Certification Authorities tab.
- In Mozilla Firefox, click
Tools >
Options >
Advanced. Then scroll down and click
Manage Certificates and click
Authorities.
- Select your Demo CA's certificate (the Common Name, not the organization name), then remove it.
- Close the browser and re-open it.
