Transfer an SSL Certificate from a Windows Server to Apache
Export an Installed SSL Certificate from a Windows Server using the Utility
To make an SSL connection, your server needs two parts, a private key the certificate files to send to clients, so they can verify the certificate comes from a trusted authority.
There are a couple of different ways that these certificate files can be exported to other servers for installation; Microsoft uses the .PFX SSL Certificate file format which combines both of these parts into a single file for installation, whereas Apache (and many other server and types) separate these two certificate parts into separate .KEY file and .CRT files.
Download and Open the DigiCert Certificate Management Utility onto the Microsoft server that the SSL certificate will be exported from.
Select the certificate you want to export and click Export.
Select the key file (Apache compatible format) option and click Next.
Choose the location and filename for your certificate key file and click Finish.
This will create the following files named that will need to be copied to your other server(s):
Private Key: your_domain_com.key
Server Certificate: your_domain_com.crt
Intermediate Certificate: DigiCertCA.crt
To enable these certificate files in Apache please consult our SSL Certificate installation instructions for Apache or find the SSL Installation Instructions for your server type that uses certificate files in Apache format.
