Importing a Server Certificate on Windows

In this use case, we import a Microsoft CA server certificate to a Windows system. In this case, the purpose is to use an SSL certificate for application offloading to a mail server.

The server certificate is mail.chaoslabs.nl. This certificate needs to be exported in base-64 format as the server.crt file that is put in a .zip file and uploaded as a Server Certificate.

The private key is not included in the .p7b file. The private key needs to be exported from wherever it is and saved in a base-64 format and included in a server.key file in the .zip file.

1
Double-click on the mail.chaoslabs.nl.pb7 file and navigate to the certificate.

2
Double-click the certificate file and select the Details tab.
3
Click Copy to File.
4
In the Certificate Export Wizard, select Base-64 encoded X.509 (.CER).
5
Click Next and save the file as server.crt on your Windows system.

The certificate is exported in base-64 encoded format.

Add the server.key file to the .zip file that contains server.crt.
