Secure a custom DNS name with an SSL binding in Azure App Service
I don´t know how you feel. Pages like https://docs.microsoft.com/en-us/azure/app-service/configure-ssl-bindings
Frist you need to upload the public certificate to Azure
In the next step you need to convert the PEM & Key to PFX. I am using here openssl for this. Note you need to you the key file you have create your SSL with.
openssl pkcs12 -export -out Zertifikat.pfx -inkey Zertifikat.key -in Zertifikat\ Server\ \(PEM\).crt -certfile Zwischenzertifik\ \(PEM\).crt
You need to confirm it with a password. Now upload the PFX file to Azure
Retry your password here.
Confirm the binding for the domain
