ListKeyPolicies

Gets the names of the key policies that are attached to a KMS key. This operation is designed to get policy names that you can use in a GetKeyPolicy operation. However, the only valid policy name is default.

Cross-account use: No. You cannot perform this operation on a KMS key in a different AWS account.

Required permissions: kms:ListKeyPolicies (key policy)

Eventual consistency: The AWS KMS API follows an eventual consistency model. For more information, see AWS KMS eventual consistency.

Request Syntax

   "KeyId": "string",
   "Limit": number,
   "Marker": "string"
}

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

Note

In the following list, the required parameters are described first.

KeyId

Gets the names of key policies for the specified KMS key.

Specify the key ID or key ARN of the KMS key.

For example:

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

To get the key ID and key ARN for a KMS key, use ListKeys or DescribeKey.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 2048.

Required: Yes

Limit

Use this parameter to specify the maximum number of items to return. When this value is present, AWS KMS does not return more than the specified number of items, but it might return fewer.

This value is optional. If you include a value, it must be between 1 and 1000, inclusive. If you do not include a value, it defaults to 100.

Only one policy can be attached to a key.

Type: Integer

Valid Range: Minimum value of 1. Maximum value of 1000.

Required: No

Marker

Use this parameter in a subsequent request after you receive a response with truncated results. Set it to the value of NextMarker from the truncated response you just received.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 1024.

Pattern: [\u0020-\u00FF]*

Required: No

Response Syntax


{
   "NextMarker": "string",
   "PolicyNames": [ "string" ],
   "Truncated": boolean
}

Response Elements

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.

NextMarker

When Truncated is true, this element is present and contains the value to use for the Marker parameter in a subsequent request.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 1024.

Pattern: [\u0020-\u00FF]*

PolicyNames

A list of key policy names. The only valid value is default.

Type: Array of strings

Length Constraints: Minimum length of 1. Maximum length of 128.

Pattern: [\w]+

Truncated

A flag that indicates whether there are more items in the list. When this value is true, the list in this response is truncated. To get more items, pass the value of the NextMarker element in this response to the Marker parameter in a subsequent request.

Type: Boolean

Errors

For information about the errors that are common to all actions, see Common Errors.

DependencyTimeoutException

The system timed out while trying to fulfill the request. You can retry the request.

HTTP Status Code: 500

InvalidArnException

The request was rejected because a specified ARN, or an ARN in a key policy, is not valid.

HTTP Status Code: 400

KMSInternalException

The request was rejected because an internal exception occurred. The request can be retried.

HTTP Status Code: 500

KMSInvalidStateException

The request was rejected because the state of the specified resource is not valid for this request.

This exceptions means one of the following:

The key state of the KMS key is not compatible with the operation.

To find the key state, use the DescribeKey operation. For more information about which key states are compatible with each AWS KMS operation, see Key states of AWS KMS keys in the AWS Key Management Service Developer Guide .
For cryptographic operations on KMS keys in custom key stores, this exception represents a general failure with many possible causes. To identify the cause, see the error message that accompanies the exception.

HTTP Status Code: 400

NotFoundException

The request was rejected because the specified entity or resource could not be found.

HTTP Status Code: 400
