Gets a list of all grants for the specified KMS key.

You must specify the KMS key in all requests. You can filter the grant list by grant ID or grantee principal.

For detailed information about grants, including grant terminology, see Using grants in the Key Management Service Developer Guide. For examples of working with grants in several programming languages, see Programming grants.

The GranteePrincipal field in the ListGrants response usually contains the user or role designated as the grantee principal in the grant. However, when the grantee principal in the grant is an Amazon Web Services service, the GranteePrincipal field contains the service principal, which might represent several different grantee principals.

Cross-account use: Yes. To perform this operation on a KMS key in a different Amazon Web Services account, specify the key ARN in the value of the KeyId parameter.

Required permissions: kms:ListGrants (key policy)

To list grants for a KMS key

var client = new AmazonKeyManagementServiceClient();
var response = client.ListGrants(new ListGrantsRequest 
    KeyId = "1234abcd-12ab-34cd-56ef-1234567890ab" // The identifier of the KMS key whose grants you want to list. You can use the key ID or the Amazon Resource Name (ARN) of the KMS key.

List<GrantListEntry> grants = response.Grants; // A list of grants.
bool truncated = response.Truncated; // A boolean that indicates whether there are more items in the list. Returns true when there are more items, or false when there are not.
