To start using HTTPS with CDN you have to provide us with certificate (and private key) for your content distribution domain in CDN cdn.domain.com or wildcard *.domain.com . In this case you can use links to your files like https://cdn.domain.com/path/to/file.mp4 but after request user will be redirected to streaming server with ahcdn.com domain URL https://ip123456.ahcdn.com/… (this is most popular scheme) .

If you want we can setup redirect to subdomains on your domain like https://ip123456.cdn.domain.com/… but this will require from you wildcard certificate for *.cdn.domain.com and delegating DNS zone for cdn.domain.com to our NSes ns1.ahcdn.com ns2.ahcdn.com ns3.ahcdn.com .
