I wanted to ask if I can create App Services managed certificates using powershell command? I tried to find such information, but unfortunately I did not manage to do so, and it would make my job much easier.
Second question - Can I find the certificate without using the thumbprint? After creating the certificate, I would like to assign it to a custom domain with a given name, but I was unable to "search" for the certificate by domain name, just using the exact thumbprint.
Thanks for any info!
There are no direct power shell command let available by you can make a use of ARM template documented here.
coming to second store, thumbprint is the only way to extract certificate either from a given file system or from certificate store.
If you want certificate with domain then you need programming certificate to iterate over each certificate and fetch domain property of X509Certificate class.

I have a strange problem when importing a certificate from Azure Key vault to be used in an App Service. As you can see in the images below, it says the certificate is imported successfully but it does not show up as expected.
This have previous worked just fine for other app services and my custom domain matches the wildcard certificate that I am trying to use.
Any ideas what causes this strange behavior?
If you choose to upload or import a private certificate to App Service, your certificate must meet the following requirements:
Exported as a password-protected PFX file, encrypted using triple DES.
Contains private key at least 2048 bits long
Contains all intermediate certificates in the certificate chain
Some certificate authorities provide certificates in different formats, therefore before importing the certificate, make sure that they are either in .pem or .pfx format.
When you are importing the certificate, you need to ensure that the
key is included in the file itself. If you have the private key
separately in a different format, you would need to combine the key
with the certificate.
you can also refer https://www.huuhka.net/app-service-imported-ssl-certificate-from-another-subscription-kv/ if you have any failure messages while importing the key vault certificate
If you are using free managed certificate , you may check its pre-requisites to be fulfilled as free certificates come with few limitations , which can be referred from https://learn.microsoft.com/en-us/azure/app-service/configure-ssl-certificate?WT.mc_id=AZ-MVP-5003781#private-certificate-requirements
So, I made a workaround solution by setting an Managed Identity on my App Service giving it correct permissions to the keyvault. And then adding the application and correct permissions in Access policies for the keyvault.
After that the certificate showed up as expected when adding a binding on my App Service.
Seems you got the right solutions and might have encountered this issue due to your logged in user RBAC role.
When ever you use app service certificate it gets stored inside Azure Key vault and to use that key vault certificate/secret you need to have access policies to get the secret and set the secret.

In the Azure App Registrations portal I need to generate a new certificate to let my domain services access the Graph.
I generate a certificate with Powershell like this:
New-SelfSignedCertificate -CertStoreLocation "Cert:\CurrentUser\My"
-Subject "CN=sampleAppCert" -KeySpec KeyExchange
The result looks good, but if I want to export this certificate with the certlm.msc to a file, it does not appear in the list.
If I add -DnsName 'my-domain.com' to the parameter list a certificate appears.
But regarding the Microsoft docs, this value should be left blank.
In general I am pretty confused to understand the different kinds of certificates and what the parameters mean.
If I use the -DnsName attribute - will this generate a SSL/TLS certificate to secure internet domains?
What does CN stand for instead?
Why is the certificate not appearing in the certlm store? How can I export my generated certificate to use it in the Azure Portal when not using the DnsName attribute.
Are there any recommandable resources to get a better understanding of digital certificates? I am very confused about the whole topic and would like to read something. But especially the microsoft docs are confusing me even more. :(
Let me try to answer your queries.
if you will use -DnsName attribute , it will will add SAN ("subject alternative name") to your certificate. you can check the SAN in the details of your certificate.
SAN is basically used to secure multiple domains using single certificate (https://www.geocerts.com/support/ssl-certificate-subject-alternative-names-sans).
Also please note that these are self signed certificates which cannot be used to secure internet domains, for securing internet domains you need certs which are signed by CA like digicerts etc.
CN stands for COMMON NAME , its basically the fully qualified domain name of your website (https://www.entrustdatacard.com/pages/digital-certificate-glossary).
you need to first export your certificate and then import it. you can use Export-PfxCertificate command to export your certificate on disk and then click it to import it.

I am trying to read Azure Configuration values and I also followed the answer provided in
Read configuration settings from azure cloud service with .NET C#
I want to know from where I can get the following parameter values:
subscriptionId
thumbprint
StoreLocation.CurrentUser
StoreLocation.LocalMachine
X509Store store = new X509Store("My", location) -- what i need to write at the place of "My"
-- what i need to write at the place of "My"
You also need to use My. For more information please refer to What are the Windows system certificate stores?
Each of the three stores contain a number of folders which certificates go into
Personal (can be known as My when using scripts to add certs)
Trusted Root Certification Authority (can be known as Root)
Enterprise Trust
Intermediate Certification Authority
Active Directory User Object
Trusted Publishers
Untrusted Certificates
Third Party Root Certification Authorities
Trusted People
We could get the subscriptionId from Azure portal, details please refer to this document.
About thumbprint please refer to How to: Retrieve the Thumbprint of a Certificate
StoreLocation.CurrentUser and StoreLocation.LocalMachine is StoreLocation Enum
I am learning about Azure Key Vault, and one of the scenarios it supports is certificate authentication, which you can read about here.
The samples do a great job of explaining how to make a self-signed certificate for local testing, which I have gotten to work without an issue. My question now is, how do I go about making a certificate for production deployments? Do I purchase this from a service somewhere? If so, what type of certificate do I need, exactly?
Unfortunately, there is no documentation anywhere that I could find in Azure Key Vault that outlines how to make (or what is expected/assumed) in a production-level certificate.
I basically have a few requirements/expectations based on my research/investigation so far:
I would like to use a trusted, external service (CA?) to purchase the certificate from.
The cheaper the certificate the better. :)
I would like to be able to create a certificate with custom data extensions.
In addition to my requirements, I have a specific question in regards to the certificate: What type of certificate do I need? Is this a server authentication certificate? Or a client authentication certificate? Or... ?
I have spent the past hour going through several SSL certificate providers, but none of them really could give me a great answer for the type of certificate I am looking for (when I provided the link to Azure certificate above to them). So, I decided to do what I should have done in the first place, and put my question up here to the esteemed community. :)
Thanks in advance for any assistance.
If you want the cert for SSL you want to get a Server Authentication certificate (it proves that the server, ie your site, is who it claims to be).
You can buy it from any trusted service and upload it to Azure Key Vault. Just google "buy ssl certificate". I think you can get one for as little as $30 if I remember correctly.
You can use Key Vault to enroll for certificate from public CAs such as DigiCert and GlobalSign. Look at the "Enroll programmatically from Public CA" section in https://blogs.technet.microsoft.com/kv/2016/09/26/get-started-with-azure-key-vault-certificates/
You can use the Key Vault REST API to programmatically enroll for certificates -https://learn.microsoft.com/en-us/rest/api/keyvault/createcertificate
The certificate policy allows for some customization like specifying which KeyUsage and EKUs you want in your certificate.
I am developing one asp.net website and I will be hosting the site on windows azure. My requirement is when user access the site like www.xyz.com\admin then live id authentication should happen but when the user access the site www.xyz.com then no need do authentication.
After referring to an MSDN document I come to know about ACS with WIF, so I created the namespace and did so on so on.
But whenever I am accessing the federation URL (https://xyz.accesscontrol.windows.net/FederationMetadata/2007-06/FederationMetadata.xml) I am getting error:
ID:1089 unable to connect the remote server.
I unfortunately deleted the certificate and keys and service identities in windows azure I don't know how to get it back, also I don't how do fulfill my requirement.
If you deleted the certificates and keys they all you need is to just create new one(s). You can either use Self Signed certificates, or use X.509 certificates issued by a trusted Certificate Authority. Once you get your X.509 certificate (it shall include a private key) you can upload it in the ACS management portal (which is locate at https://xyz.accesscontrol.windows.net/):
The FederationMedatadata.xml cannot be generated without the Token Signing certificate.
Or, the easiest for you, would be to just delete that namespace and create a new one.
