If you already have an existing SSL certificate that you would like to use for Cerberus FTP Server, you can export the certificate from the Windows certificate store to a .pfx file and then use that file directly with Cerberus FTP Server. See the step-by-step instructions below.
This article assumes that you have already successfully installed the SSL certificate on the Windows machine. You will follow these steps to move or copy that working certificate to Cerberus FTP Server:
- Export the SSL certificate from the Windows server with the private key and any intermediate certificates into a .pfx file.
- Move the .pfx certificate and private key to the certificates folder of Cerberus FTP Server.
- Configure Cerberus FTP Server to use the certificate.
