connect-custom-key-store

Description

Connects or reconnects a custom key store to its associated AWS CloudHSM cluster.

The custom key store must be connected before you can create customer master keys (CMKs) in the key store or use the CMKs it contains. You can disconnect and reconnect a custom key store at any time.

To connect a custom key store, its associated AWS CloudHSM cluster must have at least one active HSM. To get the number of active HSMs in a cluster, use the DescribeClusters operation. To add HSMs to the cluster, use the CreateHsm operation.

The connection process can take an extended amount of time to complete; up to 20 minutes. This operation starts the connection process, but it does not wait for it to complete. When it succeeds, this operation quickly returns an HTTP 200 response and a JSON object with no properties. However, this response does not indicate that the custom key store is connected. To get the connection state of the custom key store, use the DescribeCustomKeyStores operation.

During the connection process, AWS KMS finds the AWS CloudHSM cluster that is associated with the custom key store, creates the connection infrastructure, connects to the cluster, logs into the AWS CloudHSM client as the ` kmsuser crypto user <https://docs.aws.amazon.com/kms/latest/developerguide/key-store-concepts.html#concept-kmsuser>`__ (CU), and rotates its password.

The ConnectCustomKeyStore operation might fail for various reasons. To find the reason, use the DescribeCustomKeyStores operation and see the ConnectionErrorCode in the response. For help interpreting the ConnectionErrorCode , see CustomKeyStoresListEntry .

To fix the failure, use the DisconnectCustomKeyStore operation to disconnect the custom key store, correct the error, use the UpdateCustomKeyStore operation if necessary, and then use ConnectCustomKeyStore again.

If you are having trouble connecting or disconnecting a custom key store, see Troubleshooting a Custom Key Store in the AWS Key Management Service Developer Guide .

Synopsis

  connect-custom-key-store
--custom-key-store-id <value>
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

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

Enter the key store ID of the custom key store that you want to connect. To find the ID of a custom key store, use the DescribeCustomKeyStores operation.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI 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.

--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. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.

Examples

To connect a custom key store

The following connect-custom-key-store example reconnects the specified custom key store. You can use a command like this one to connect a custom key store for the first time or to reconnect a key store that was disconnected.

aws kms connect-custom-key-store \
    --custom-key-store-id cks-1234567890abcdef0

This command does not return any output. To verify that the command was effective, use the describe-custom-key-stores command.

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