Hello,  You will have to create a CSR and a key by yourself. Personnally I'm using openssl for that. Then you will have to create a certificate with certificate authority and copy the certificate and the public key to the Unity with a tool like WinSCP. Be aware that the certificate file and the key should have the same name (for example unity.crt and unity.pk) and they have to be stored in the same folder. You can then import the certificate into the Unity with the command svc_custom_cert  Please let me know if you need more details.  Regards,  Erwan
