View expiry date of certificate inside a pfx file stored in Azure KeyVault

This may seem like a very basic question, but I've created a KeyVault in Azure and have added a pfx file containing a certificate/publickey to it .

Now using C# code I'm trying to access the public key and from that I want get the expiry-date attribute details. I can see that the certificate expiry date from the certificate manager utility in windows, however I can't seem to work out any way to actually retrieve the same thing in my c# code.

//Below is the code i'm using KeyVaultClient client = new KeyVaultClient(GetAccessToken); var keyBundle = client.GetKeyAsync(vaultUri, wrappingKeyName).Result; // After this KeyBundle.Key doesn't have the necessary details

Can anyone provide the missing link, as the current documentation on the Microsoft site isn't too expansive at present.

You should be able to get the Expiry from the key bundle as below

var keyIdentifier = "https://rahulkeyvault.vault.azure.net:443/keys/NewKey";
var key = await keyClient.GetKeyAsync(keyIdentifier);
var keyExpiry = key.Attributes.Expires;

This depends on if you have mentioned an expiry at the time of creating the key by setting the -Expires flag
