Get the expiration date on an Azure storage account-lvel SAS? - azure-storage

Question

I'm looking for a way to find any expired or expiring SAS signatures on an Azure storage account.
Using C# I have examined all the public properties and methods of the CloudStorageAccount class, I have also looked at this class in ILSpy and Azure Resource explorer - just can't see a way to retrieve the SAS expiry date/time.
void Main()
{
CloudStorageAccount account = new CloudStorageAccount(new
StorageCredentials(GetName(), GetKey()), true);
account.Dump();
CloudBlobClient client = account.CreateCloudBlobClient();
foreach (CloudBlobContainer container in client.ListContainers())
{
var sabp = new SharedAccessBlobPolicy();
var sas = container.GetSharedAccessSignature(sabp);
Console.WriteLine(container.Name);
Console.WriteLine(sas);
Console.WriteLine();
}
}
internal string GetName() {return #"myaccountname";}
internal string GetKey() {return #"myaccountkey";}
The is no error but also no way (I can see) to get the account-level SAS.
Note I do not want any blob SAS but the SAS set against the container.
Thanks

If you want to know if your account-level SAS is expired or expiring of , based on this doc , you can just check the SignedExpiry param. in SAS , its name is se.
Try the code below to get a account-level SAS with blob object read permission and has 1 day's lifetime:
static void Main(string[] args)
{
CloudStorageAccount account = new CloudStorageAccount(new StorageCredentials("<storage account name>", "<storage key>"), true);
var accesspolicy = new SharedAccessAccountPolicy()
{
Permissions = SharedAccessAccountPermissions.Read,
Services = SharedAccessAccountServices.Blob,
SharedAccessExpiryTime = DateTime.UtcNow.AddDays(1),
ResourceTypes = SharedAccessAccountResourceTypes.Object
};
var accountSAS = account.GetSharedAccessSignature(accesspolicy);
Console.WriteLine(accountSAS);
Console.ReadKey();
}
Result :
As you can see, the se param is there and indicates this sas will expire after 1 day.
So you can use this sas to access your blobs :
