Referring to the question asked here, Azure: manually add app service certificate to key vault
Also quoting to answer given,
" App Service Certificate stores the private certificate into a user-provided Key Vault secret. When App Service Certificate is deployed into a web app, a Web Apps resource provider deploys it from the Key Vault secret that's associated with App Service Certificate.
So, when you add app service certificate to azure keyvault, you could not see anything in Certificate option. "
As I cannot see certificates in the key vault but the certificate is stored in user provided secret, but how to export it then?

I was trying to see if the purpose of this TLS/SSL settings in function app is similar to the cert store? i.e. can we store a public cert in this section of the function app and let function app access the public cert in the code by getting the cert from this location? If yes, is there any sample that I can take a look into?

The purpose of this TLS/SSL settings in function app is not similar to the cert store.
A certificate uploaded into an app is stored in a deployment unit that is bound to the app service plan's resource group and region combination (internally called a webspace). This makes the certificate accessible to other apps in the same resource group and region combination.
If you are using cert store( key vault ) to store you ssl certificates then you need to pass the key vault certificate uri as application setting to the functions app.
can we store a public cert in this section of the function app and let
function app access the public cert in the code by getting the cert
from this location? If yes, is there any sample that I can take a look
into?
As per the Azure documentation , you can store the public cert under the function app ttl/ssl settings & refer this documentation for accessing the certificate in your application code.
Created an app service certificate in Azure to enable SSL for Application Gateway.
Had already configured SSL on the Application Gateway with a self-signed .pfx certificate to test the functionality but wanted to go with a more robust, auto-renewed and Microsoft managed solution.
However, it seems that an "App Service Certificate" is not the same as a generic certificate and doesn't show up on the listener options config page on the Application Gateway when trying to add the cert from key vault to the app gateway.
Is there any way to re-use this certificate with the Application Gateway?
I came across this today and found out that it is the 'Azure Portal' that is incapable of adding a certificate stored as key vault secret. If you use Terraform/REST API/Az CLI etc, you can add a key vault secret to Application Gateway.
This is already documented by MS.
The Azure portal supports only Key Vault certificates, not secrets. Application Gateway still supports referencing secrets from Key Vault, but only through non-portal resources like PowerShell, the Azure CLI, APIs, and Azure Resource Manager templates (ARM templates).
Again, there is a partially correct warning which is only true for 'Azure Portal'
Azure Application Gateway currently supports only Key Vault accounts in the same subscription as the Application Gateway resource. Choosing a key vault under a different subscription than your Application Gateway will result in a failure.
A simple but manual solution is to download the certificate from key vault secret via Azure Portal and upload it as a key vault certificate. You will need to do this again when the certificate is renewed.
My Azure App service is loading a certificate from the Azure Key Vault. I have set cert as auto-renew in key vault. My appservice is loading the new certificate, whenever Keyvault renews the cert.
I know AppService keep syncing with Azure Key Vault in a background process. How does it happen when AppService finds there is a renewed certificate in Key Vault? Does appservice loads new renewed cert in the Current User and restart the AppService?
Thanks
How does it happen when AppService finds there is a renewed certificate in Key Vault?
The Web App service runs a background job that periodically (once a day ) that syncs all App Service certificate. Hence when you rotate or update a certificate, sometimes the application is still retrieving the old certificate and not the newly updated certificate. This is because the job has not run to sync the certificate resource. It will automatically update the hostname bindings for the certificate in App Service within 48 hours.
Does app service loads new renewed cert in the Current User and restart the AppService?
It will automatically updates the certificate in App Service without causing any downtime to your apps.
I want to know how can we move an app service certificate with all the webapps.
In my case webapps contains other certificate thumbprints and it also contains App service certificates thumbprint, and we have various app services distribute in 4 RG and the app service certificate and keyvault are in another resource group, how should I move those across subscription.
Should I delete all the certificates from the webapps and then move them?
Or should I only delete the certificate thumbprints and leave the app service certificate thumbprint into the appservice and then move them all together with the app service certificate.
I am looking for a best practice measure in this scenario anyone performed this before?
You can move App Service Certificates to a new resource group or subscription without limitations. If you have multiple web apps that use the same App Service Certificate, first move all the web apps, then move the certificate.
Note that, you can move an App Service Certificate to a new resource group or subscription without any issues. However, if your web app includes an SSL certificate that you purchased externally and uploaded to the app, you must delete the certificate before moving the web app. For example, you can perform the following steps:
Delete the uploaded certificate from the web app
Move the web app
Upload the certificate to the web app
Refer the App Service limitations for more details.
Hope this helps.
I have a worker role that is used to provision databases. In order to do this it has to hit the Azure Management API and to do this it requires a certificate.
You can store certificates in the portal against the subscription (Settings tab) or against individual cloud services. Where should the certificate be stored?
Worker role that needs to talk to Management API needs to have the .PFX certificate uploaded into it as if it is an SSL cert (against individual service).
Matching public cert (.cer) needs to be uploaded to the Management Certificates area, against the subscription itself.
