To install a certificate on Windows, you use the CertMaker utility. CertMaker uses a certificate which you copy and paste from a certificate response email message from a Certificate Authority.
To install a certificate, follow these steps:
If you followed the instructions in Requesting certificates with CertMaker, the Certificate Authority should send you a certificate response email.
The CertMaker utility appears.
A dialog box prompting you for a certificate appears.
By default, CertMaker looks for the last private key file it created. If you need to use a different key, be sure to select it by clicking the button next to the Private Key File field.
CertMaker parses the input certificate file and extracts the issued certificate from the mail message body. It then inserts the private key into the certificate and installs the results in an output certificate (.pem) file in the same directory as the private key file. It forms the certificate filename by appending a .pem extension to the basename of the private key file. For example, if the private key file name is mycert.pvk, the name of the certificate file will be mycert.pem.
