How to Edit a Digital Certificateby Stephen Lilley
A digital certificate, also called an SSL certificate, is a digital file downloaded to your computer via your Web browser when you attempt to load a secure Web page. This certificate authenticates the page as secure in the eyes of your Web browser. If you want to make any edits to the contents of the certificate, you can do so using tools native to your computer's default Web browsing software, Internet Explorer.
Open Internet Explorer.
Click "Internet Options."
Click "Certificates." Double-click on the listing for the digital certificate you want to edit. Make the appropriate changes with your keyboard and mouse by changing the values listed in the boxes onscreen. Click "OK" to save your changes.
