describe-custom-key-stores¶

Description¶

Gets information about custom key stores in the account and Region.

This operation is part of the custom key store feature feature in KMS, which combines the convenience and extensive integration of KMS with the isolation and control of a single-tenant key store.

By default, this operation returns information about all custom key stores in the account and Region. To get only information about a particular custom key store, use either the CustomKeyStoreName or CustomKeyStoreId parameter (but not both).

To determine whether the custom key store is connected to its CloudHSM cluster, use the ConnectionState element in the response. If an attempt to connect the custom key store failed, the ConnectionState value is FAILED and the ConnectionErrorCode element in the response indicates the cause of the failure. For help interpreting the ConnectionErrorCode , see CustomKeyStoresListEntry .

Custom key stores have a DISCONNECTED connection state if the key store has never been connected or you use the DisconnectCustomKeyStore operation to disconnect it. If your custom key store state is CONNECTED but you are having trouble using it, make sure that its associated CloudHSM cluster is active and contains the minimum number of HSMs required for the operation, if any.

For help repairing your custom key store, see the Troubleshooting Custom Key Stores topic in the Key Management Service Developer Guide .

Cross-account use : No. You cannot perform this operation on a custom key store in a different Amazon Web Services account.

Required permissions : kms:DescribeCustomKeyStores (IAM policy)

Synopsis¶

  describe-custom-key-stores
[--custom-key-store-id <value>]
[--custom-key-store-name <value>]
[--cli-input-json | --cli-input-yaml]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]

Options¶

--custom-key-store-id (string)

Gets only information about the specified custom key store. Enter the key store ID.

By default, this operation gets information about all custom key stores in the account and Region. To limit the output to a particular custom key store, you can use either the CustomKeyStoreId or CustomKeyStoreName parameter, but not both.

--custom-key-store-name (string)

Gets only information about the specified custom key store. Enter the friendly name of the custom key store.

By default, this operation gets information about all custom key stores in the account and Region. To limit the output to a particular custom key store, you can use either the CustomKeyStoreId or CustomKeyStoreName parameter, but not both.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command’s output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command’s output. If the total number of items available is more than the value specified, a NextToken is provided in the command’s output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

See ‘aws help’ for descriptions of global parameters.

Examples¶

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To get details about a custom key store

The following describe-custom-key-store example displays details for the specified custom key store.

To identify a particular custom key store, use the custom-key-store-name or custom-key-store-id parameter. To get all custom key stores in the account and Region, omit all parameters.

aws kms describe-custom-key-stores \
    --custom-key-store-name ExampleKeyStore

The output of this command includes useful details about the custom key store including its connection state (ConnectionState). If the connection state is FAILED, the output includes a ConnectionErrorCode field that describes the problem.

Output:

{
    "CustomKeyStores": [
        {
            "CloudHsmClusterId": "cluster-1a23b4cdefg",
            "ConnectionState": "CONNECTED",
            "CreationDate": "1.599288695918E9",
            "CustomKeyStoreId": "cks-1234567890abcdef0",
            "CustomKeyStoreName": "ExampleKeyStore",
            "TrustAnchorCertificate": "<certificate appears here>"
        }
    ]
}

For more information, see Viewing a Custom Key Store in the AWS Key Management Service Developer Guide.

Output¶

CustomKeyStores -> (list)

Contains metadata about each custom key store.

(structure)

Contains information about each custom key store in the custom key store list.

CustomKeyStoreId -> (string)

A unique identifier for the custom key store.

CustomKeyStoreName -> (string)

The user-specified friendly name for the custom key store.

CloudHsmClusterId -> (string)

A unique identifier for the CloudHSM cluster that is associated with the custom key store.

TrustAnchorCertificate -> (string)

The trust anchor certificate of the associated CloudHSM cluster. When you initialize the cluster , you create this certificate and save it in the customerCA.crt file.

ConnectionState -> (string)

Indicates whether the custom key store is connected to its CloudHSM cluster.

You can create and use KMS keys in your custom key stores only when its connection state is CONNECTED .

The value is DISCONNECTED if the key store has never been connected or you use the DisconnectCustomKeyStore operation to disconnect it. If the value is CONNECTED but you are having trouble using the custom key store, make sure that its associated CloudHSM cluster is active and contains at least one active HSM.

A value of FAILED indicates that an attempt to connect was unsuccessful. The ConnectionErrorCode field in the response indicates the cause of the failure. For help resolving a connection failure, see Troubleshooting a Custom Key Store in the Key Management Service Developer Guide .

ConnectionErrorCode -> (string)

Describes the connection error. This field appears in the response only when the ConnectionState is FAILED . For help resolving these errors, see How to Fix a Connection Failure in Key Management Service Developer Guide .

Valid values are:

CLUSTER_NOT_FOUND - KMS cannot find the CloudHSM cluster with the specified cluster ID.

INSUFFICIENT_CLOUDHSM_HSMS - The associated CloudHSM cluster does not contain any active HSMs. To connect a custom key store to its CloudHSM cluster, the cluster must contain at least one active HSM.

INTERNAL_ERROR - KMS could not complete the request due to an internal error. Retry the request. For ConnectCustomKeyStore requests, disconnect the custom key store before trying to connect again.

INVALID_CREDENTIALS - KMS does not have the correct password for the kmsuser crypto user in the CloudHSM cluster. Before you can connect your custom key store to its CloudHSM cluster, you must change the kmsuser account password and update the key store password value for the custom key store.

NETWORK_ERRORS - Network errors are preventing KMS from connecting to the custom key store.

SUBNET_NOT_FOUND - A subnet in the CloudHSM cluster configuration was deleted. If KMS cannot find all of the subnets in the cluster configuration, attempts to connect the custom key store to the CloudHSM cluster fail. To fix this error, create a cluster from a recent backup and associate it with your custom key store. (This process creates a new cluster configuration with a VPC and private subnets.) For details, see How to Fix a Connection Failure in the Key Management Service Developer Guide .

USER_LOCKED_OUT - The kmsuser CU account is locked out of the associated CloudHSM cluster due to too many failed password attempts. Before you can connect your custom key store to its CloudHSM cluster, you must change the kmsuser account password and update the key store password value for the custom key store.

USER_LOGGED_IN - The kmsuser CU account is logged into the the associated CloudHSM cluster. This prevents KMS from rotating the kmsuser account password and logging into the cluster. Before you can connect your custom key store to its CloudHSM cluster, you must log the kmsuser CU out of the cluster. If you changed the kmsuser password to log into the cluster, you must also and update the key store password value for the custom key store. For help, see How to Log Out and Reconnect in the Key Management Service Developer Guide .

USER_NOT_FOUND - KMS cannot find a kmsuser CU account in the associated CloudHSM cluster. Before you can connect your custom key store to its CloudHSM cluster, you must create a kmsuser CU account in the cluster, and then update the key store password value for the custom key store.

CreationDate -> (timestamp)

The date and time when the custom key store was created.

NextMarker -> (string)

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

Truncated -> (boolean)

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 thisresponse to the Marker parameter in a subsequent request.
