I want to link a key vault generated certificate with a service principal automatically. The end goal is to have the key vault auto renew the certificate and link it to the app registration. Is this possible?

Azure Key Vault is a cloud service that enables the secure storage and access of secrets and keys. Your Verifiable Credentials service stores public and private keys in Azure Key Vault. These keys are used to sign and verify credentials.
https://learn.microsoft.com/en-us/azure/active-directory/verifiable-credentials/verifiable-credentials-configure-tenant
How can we find our Public and Private key for verifiable credentials?
I can see Recovery, Signing, and Update key in my Key Vault used for VC.
• Recovery, signing, and encrypting are various key management and cryptographic operations that are needed to be selected while creating an access policy for the said user selected thus limiting the scope of operations that can be performed by the keys, secrets and certificates issued by that user.
Similarly, the private key and the public key of the verifiable credential cannot be accessible by the ‘USER’ as the user has delegated that authority to the application registered in Azure AD with the permissions ‘VerifiableCredential.Create.All’ and this application registered in Azure AD has been granted API permission for the API Verifiable Credential Request Service. Thus, the private key is generated and is with the service principal of the Azure resource which issues a ‘Verifiable credential’ through the registered Azure AD application to create a key, secret, or a certificate in the Azure keyvault.
• While the public key is with the key, secret or certificate generated in the Azure key vault thus, completing the nexus of secure communication through the concerned application hosted. Thus, in this way, just based on RBAC (Role Based Access Control) and the ensuing access policy actions created in the key vault, you can create secure communication through the web app without exposing the private and the public keys.

We are managing our customers' azure subscriptions using Microsoft Partner Centre >> and using a username I create a new Azure Vault for a customer>> but when I tried to create a new Secret inside the Azure Vault , I got this error:-
The operation "Set" is not enabled in this key vault's access policy.
now when I access the Key Vault >> Access Policy >> I am unable to add the login username which I used to create the Key Vault inside the Key Vault access policy, where I am only able to add the office 365 admin:-
so any advice why i am able to create a new Key Vault, while i am unable to add Secrets inside it?
When you create the Key vault, you should add the CSP access policy rather than normal access policy.
After you click on it, you can specify CSP security group (it has shown the steps to get the group id).
Then the CSP user can create secret in this key vault after it's created.
I have added below properties to arm template (link) to create storage accounts and encrypt them with customer managed keys.
"keySource": "Microsoft.Keyvault",
"keyvaultproperties": {
"keyname": "xxxx",
"keyversion": "xxxxxx",
"keyvaulturi": "xxxxxxx"
}
But when I try to create this resource I get
"Missing pre-requisites to enable EncryptionAtRest/Customer Managed
Key for this storage account."
The reason is the storage account service principal(managed idendity) is not having access to the encryption key in Azure key vault. You cannot give the access in advance until storage account (service principal - managed idendity) is created.
But I see that the storage account managed identity is not created automatically. It is created at the time when we enable the encryption.
I have faced this too, MS doc and this answer were helpeful.
Here is why this is happening actually ( from the MS doc ) :
Choose a managed identity to authorize access to the key vault
When you enable customer-managed keys for a storage account, you must specify a managed identity that will be used to authorize access to the key vault that contains the key. The managed identity must have permissions to access the key in the key vault.
The managed identity that authorizes access to the key vault may be either a user-assigned or system-assigned managed identity, depending on your scenario:
When you configure customer-managed keys at the time that you create a storage account, you must specify a user-assigned managed identity.
When you configure customer-managed keys on an existing storage account, you can specify either a user-assigned managed identity or a system-assigned managed identity.
I am trying to authenticate a local hadoop cluster to Azure using a service principal and certificate authentication. I have created a service principal, and put had the key vault create the certificate. I know how to get that information once I am authenticated, but I am trying to figure out how I would re-authenticate automatically once the certificate expires.
I've created a vault in Azure and gave it access to API management (registered app in AAD). I'm trying to not store any passwords in header while making API calls, but instead get them from the keyvault. Is there a way to do this? If yes how?
Been looking for days and haven't found something
Thanks
You need to use API Management Policy to get the job done (https://learn.microsoft.com/en-us/azure/api-management/api-management-policies).
The policy needs to be constructed to post HTTP request to Azure AD OAuth endpoint to receive access token (https://learn.microsoft.com/en-us/azure/api-management/api-management-transformation-policies#TransformationPolicies). Using access token you just need to call to Key Vault API and retrieve the secret (https://learn.microsoft.com/en-us/azure/api-management/api-management-advanced-policies#SendRequest). That secret will be passed along in your header (set-header)
Sample to get access token: https://learn.microsoft.com/en-us/azure/api-management/policies/use-oauth2-for-authorization?toc=api-management/toc.json
Here is an end to end example of Azure API Management and Azure Key Vault, including how to setup authorization in Azure AD so APIM can read secrets, certificates, etc. from Key Vault.
https://github.com/kevinhillinger/azure-api-management-keyvault
The integration requires that a service principal is registered in the Azure AD tenant for the subscription that the Key Vault instance belongs to. Then we're going to authorize it to talk to key vault.
In the example provided, I am retrieving a certificate since this is the more "difficult" option.
Here is the flow for the integration of Azure Key Vault:
Get a minted token (bearer) from Azure AD (make sure the scope is properly set for Key Vault)
Get the response and set a variable with the token value
Send a request to Key Vault with Authorization header loaded up with the token
Get the certificate info
Fetch the entire PFX file in base64
