The DescribeKeyRequest type exposes the following members


Public Method DescribeKeyRequest()


Public Property GrantTokens System.Collections.Generic.List<System.String>

A list of grant tokens.

For more information, see Grant Tokens in the AWS Key Management Service Developer Guide.

Public Property KeyId System.String

Gets and sets the property KeyId.

A unique identifier for the customer master key (CMK).

To specify a CMK, use its key ID, Amazon Resource Name (ARN), alias name, or alias ARN. When using an alias name, prefix it with "alias/". To specify a CMK in a different AWS account, you must use the key ARN or alias ARN.

For example:

  • Key ID: 1234abcd-12ab-34cd-56ef-1234567890ab

  • Key ARN: arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab

  • Alias name: alias/ExampleAlias

  • Alias ARN: arn:aws:kms:us-east-2:111122223333:alias/ExampleAlias

To get the key ID and key ARN for a CMK, use ListKeys or DescribeKey. To get the alias name and alias ARN, use ListAliases.


The following example returns information (metadata) about the specified CMK.

To obtain information about a customer master key (CMK)

var response = client.DescribeKey(new DescribeKeyRequest 
    KeyId = "1234abcd-12ab-34cd-56ef-1234567890ab" // The identifier of the CMK that you want information about. You can use the key ID or the Amazon Resource Name (ARN) of the CMK.

KeyMetadata keyMetadata = response.KeyMetadata; // An object that contains information about the specified CMK.
