create-custom-key-store¶

Description¶

Creates a custom key store backed by a key store that you own and manage. When you use a KMS key in a custom key store for a cryptographic operation, the cryptographic operation is actually performed in your key store using your keys. KMS supports CloudHSM key stores backed by an CloudHSM cluster and external key stores backed by an external key store proxy and external key manager outside of Amazon Web Services.

This operation is part of the custom key stores feature in KMS, which combines the convenience and extensive integration of KMS with the isolation and control of a key store that you own and manage.

Before you create the custom key store, the required elements must be in place and operational. We recommend that you use the test tools that KMS provides to verify the configuration your external key store proxy. For details about the required elements and verification tests, see Assemble the prerequisites (for CloudHSM key stores) or Assemble the prerequisites (for external key stores) in the Key Management Service Developer Guide .

To create a custom key store, use the following parameters.

To create an CloudHSM key store, specify the CustomKeyStoreName , CloudHsmClusterId , KeyStorePassword , and TrustAnchorCertificate . The CustomKeyStoreType parameter is optional for CloudHSM key stores. If you include it, set it to the default value, AWS_CLOUDHSM . For help with failures, see Troubleshooting an CloudHSM key store in the Key Management Service Developer Guide .
To create an external key store, specify the CustomKeyStoreName and a CustomKeyStoreType of EXTERNAL_KEY_STORE . Also, specify values for XksProxyConnectivity , XksProxyAuthenticationCredential , XksProxyUriEndpoint , and XksProxyUriPath . If your XksProxyConnectivity value is VPC_ENDPOINT_SERVICE , specify the XksProxyVpcEndpointServiceName parameter. For help with failures, see Troubleshooting an external key store in the Key Management Service Developer Guide .

Note

For external key stores:

Some external key managers provide a simpler method for creating an external key store. For details, see your external key manager documentation.

When creating an external key store in the KMS console, you can upload a JSON-based proxy configuration file with the desired values. You cannot use a proxy configuration with the CreateCustomKeyStore operation. However, you can use the values in the file to help you determine the correct values for the CreateCustomKeyStore parameters.

When the operation completes successfully, it returns the ID of the new custom key store. Before you can use your new custom key store, you need to use the ConnectCustomKeyStore operation to connect a new CloudHSM key store to its CloudHSM cluster, or to connect a new external key store to the external key store proxy for your external key manager. Even if you are not going to use your custom key store immediately, you might want to connect it to verify that all settings are correct and then disconnect it until you are ready to use it.

For help with failures, see Troubleshooting a custom key store 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:CreateCustomKeyStore (IAM policy).

Options¶

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

Specifies a friendly name for the custom key store. The name must be unique in your Amazon Web Services account and Region. This parameter is required for all custom key stores.

Warning
Do not include confidential or sensitive information in this field. This field may be displayed in plaintext in CloudTrail logs and other output.

--cloud-hsm-cluster-id (string)

Identifies the CloudHSM cluster for an CloudHSM key store. This parameter is required for custom key stores with CustomKeyStoreType of AWS_CLOUDHSM .

Enter the cluster ID of any active CloudHSM cluster that is not already associated with a custom key store. To find the cluster ID, use the DescribeClusters operation.

--trust-anchor-certificate (string)

Specifies the certificate for an CloudHSM key store. This parameter is required for custom key stores with a CustomKeyStoreType of AWS_CLOUDHSM .

Enter the content of the trust anchor certificate for the CloudHSM cluster. This is the content of the customerCA.crt file that you created when you initialized the cluster .

--key-store-password (string)

Specifies the kmsuser password for an CloudHSM key store. This parameter is required for custom key stores with a CustomKeyStoreType of AWS_CLOUDHSM .

Enter the password of the ` kmsuser crypto user (CU) account <https://docs.aws.amazon.com/kms/latest/developerguide/key-store-concepts.html#concept-kmsuser>`__ in the specified CloudHSM cluster. KMS logs into the cluster as this user to manage key material on your behalf.

The password must be a string of 7 to 32 characters. Its value is case sensitive.

This parameter tells KMS the kmsuser account password; it does not change the password in the CloudHSM cluster.

--custom-key-store-type (string)

Specifies the type of custom key store. The default value is AWS_CLOUDHSM .

For a custom key store backed by an CloudHSM cluster, omit the parameter or enter AWS_CLOUDHSM . For a custom key store backed by an external key manager outside of Amazon Web Services, enter EXTERNAL_KEY_STORE . You cannot change this property after the key store is created.

Possible values:

AWS_CLOUDHSM

EXTERNAL_KEY_STORE

--xks-proxy-uri-endpoint (string)

Specifies the endpoint that KMS uses to send requests to the external key store proxy (XKS proxy). This parameter is required for custom key stores with a CustomKeyStoreType of EXTERNAL_KEY_STORE .

The protocol must be HTTPS. KMS communicates on port 443. Do not specify the port in the XksProxyUriEndpoint value.

For external key stores with XksProxyConnectivity value of VPC_ENDPOINT_SERVICE , specify https:// followed by the private DNS name of the VPC endpoint service.

For external key stores with PUBLIC_ENDPOINT connectivity, this endpoint must be reachable before you create the custom key store. KMS connects to the external key store proxy while creating the custom key store. For external key stores with VPC_ENDPOINT_SERVICE connectivity, KMS connects when you call the ConnectCustomKeyStore operation.

The value of this parameter must begin with https:// . The remainder can contain upper and lower case letters (A-Z and a-z), numbers (0-9), dots (. ), and hyphens (- ). Additional slashes (/ and \ ) are not permitted.

Uniqueness requirements:

The combined XksProxyUriEndpoint and XksProxyUriPath values must be unique in the Amazon Web Services account and Region.

An external key store with PUBLIC_ENDPOINT connectivity cannot use the same XksProxyUriEndpoint value as an external key store with VPC_ENDPOINT_SERVICE connectivity in this Amazon Web Services Region.

Each external key store with VPC_ENDPOINT_SERVICE connectivity must have its own private DNS name. The XksProxyUriEndpoint value for external key stores with VPC_ENDPOINT_SERVICE connectivity (private DNS name) must be unique in the Amazon Web Services account and Region.

--xks-proxy-uri-path (string)

Specifies the base path to the proxy APIs for this external key store. To find this value, see the documentation for your external key store proxy. This parameter is required for all custom key stores with a CustomKeyStoreType of EXTERNAL_KEY_STORE .

The value must start with / and must end with /kms/xks/v1 where v1 represents the version of the KMS external key store proxy API. This path can include an optional prefix between the required elements such as /*prefix* /kms/xks/v1 .

Uniqueness requirements:

The combined XksProxyUriEndpoint and XksProxyUriPath values must be unique in the Amazon Web Services account and Region.

--xks-proxy-vpc-endpoint-service-name (string)

Specifies the name of the Amazon VPC endpoint service for interface endpoints that is used to communicate with your external key store proxy (XKS proxy). This parameter is required when the value of CustomKeyStoreType is EXTERNAL_KEY_STORE and the value of XksProxyConnectivity is VPC_ENDPOINT_SERVICE .

The Amazon VPC endpoint service must fulfill all requirements for use with an external key store.

Uniqueness requirements:

External key stores with VPC_ENDPOINT_SERVICE connectivity can share an Amazon VPC, but each external key store must have its own VPC endpoint service and private DNS name.

--xks-proxy-authentication-credential (structure)

Specifies an authentication credential for the external key store proxy (XKS proxy). This parameter is required for all custom key stores with a CustomKeyStoreType of EXTERNAL_KEY_STORE .

The XksProxyAuthenticationCredential has two required elements: RawSecretAccessKey , a secret key, and AccessKeyId , a unique identifier for the RawSecretAccessKey . For character requirements, see XksProxyAuthenticationCredentialType .

KMS uses this authentication credential to sign requests to the external key store proxy on your behalf. This credential is unrelated to Identity and Access Management (IAM) and Amazon Web Services credentials.

This parameter doesn't set or change the authentication credentials on the XKS proxy. It just tells KMS the credential that you established on your external key store proxy. If you rotate your proxy authentication credential, use the UpdateCustomKeyStore operation to provide the new credential to KMS.

AccessKeyId -> (string)

A unique identifier for the raw secret access key.

RawSecretAccessKey -> (string)

A secret string of 43-64 characters. Valid characters are a-z, A-Z, 0-9, /, +, and =.

Shorthand Syntax:

AccessKeyId=string,RawSecretAccessKey=string

JSON Syntax:

{
  "AccessKeyId": "string",
  "RawSecretAccessKey": "string"
}

--xks-proxy-connectivity (string)

Indicates how KMS communicates with the external key store proxy. This parameter is required for custom key stores with a CustomKeyStoreType of EXTERNAL_KEY_STORE .

If the external key store proxy uses a public endpoint, specify PUBLIC_ENDPOINT . If the external key store proxy uses a Amazon VPC endpoint service for communication with KMS, specify VPC_ENDPOINT_SERVICE . For help making this choice, see Choosing a connectivity option in the Key Management Service Developer Guide .

An Amazon VPC endpoint service keeps your communication with KMS in a private address space entirely within Amazon Web Services, but it requires more configuration, including establishing a Amazon VPC with multiple subnets, a VPC endpoint service, a network load balancer, and a verified private DNS name. A public endpoint is simpler to set up, but it might be slower and might not fulfill your security requirements. You might consider testing with a public endpoint, and then establishing a VPC endpoint service for production tasks. Note that this choice does not determine the location of the external key store proxy. Even if you choose a VPC endpoint service, the proxy can be hosted within the VPC or outside of Amazon Web Services such as in your corporate data center.

Possible values:

PUBLIC_ENDPOINT

VPC_ENDPOINT_SERVICE

--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.

Global Options¶

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

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 .

Example 1: To create an AWS CloudHSM key store

The following create-custom-key-store example creates an AWS CloudHSM key store backed by an AWS CloudHSM cluster using the required parameters. You can also add the custom-key-store-type``parameter with the default value: ``AWS_CLOUDHSM.

To specify the file input for the trust-anchor-certificate command in the AWS CLI, the file:// prefix is required.

aws kms create-custom-key-store \
    --custom-key-store-name ExampleCloudHSMKeyStore \
    --cloud-hsm-cluster-id cluster-1a23b4cdefg \
    --key-store-password kmsPswd \
    --trust-anchor-certificate file://customerCA.crt

Output:

{
    "CustomKeyStoreId": cks-1234567890abcdef0
}

For more information, see Creating an AWS CloudHSM key store in the AWS Key Management Service Developer Guide.

Example 2: To create an external key store with public endpoint connectivity

The following create-custom-key-store example creates an external key store (XKS) that communicates with AWS KMS over the internet.

In this example, the XksProxyUriPath uses an optional prefix of example-prefix.

NOTE: If you use AWS CLI version 1.0, run the following command before specifying a parameter with an HTTP or HTTPS value, such as the XksProxyUriEndpoint parameter.

aws configure set cli_follow_urlparam false

Otherwise, AWS CLI version 1.0 replaces the parameter value with the content found at that URI address.

aws kms create-custom-key-store \
    --custom-key-store-name ExamplePublicEndpointXKS \
    --custom-key-store-type EXTERNAL_KEY_STORE \
    --xks-proxy-connectivity PUBLIC_ENDPOINT \
    --xks-proxy-uri-endpoint "https://myproxy.xks.example.com" \
    --xks-proxy-uri-path "/example-prefix/kms/xks/v1" \
    --xks-proxy-authentication-credential "AccessKeyId=ABCDE12345670EXAMPLE, RawSecretAccessKey=DXjSUawnel2fr6SKC7G25CNxTyWKE5PF9XX6H/u9pSo="

Output:

{
    "CustomKeyStoreId": cks-2234567890abcdef0
}

For more information, see Creating an external key store in the AWS Key Management Service Developer Guide.

Example 3: To create an external key store with VPC endpoint service connectivity

The following create-custom-key-store example creates an external key store (XKS) that uses an Amazon VPC endpoint service to communicate with AWS KMS.

NOTE: If you use AWS CLI version 1.0, run the following command before specifying a parameter with an HTTP or HTTPS value, such as the XksProxyUriEndpoint parameter.

aws configure set cli_follow_urlparam false

Otherwise, AWS CLI version 1.0 replaces the parameter value with the content found at that URI address.

aws kms create-custom-key-store \
    --custom-key-store-name ExampleVPCEndpointXKS \
    --custom-key-store-type EXTERNAL_KEY_STORE \
    --xks-proxy-connectivity VPC_ENDPOINT_SERVICE \
    --xks-proxy-uri-endpoint "https://myproxy-private.xks.example.com" \
    --xks-proxy-uri-path "/kms/xks/v1" \
    --xks-proxy-vpc-endpoint-service-name "com.amazonaws.vpce.us-east-1.vpce-svc-example1" \
    --xks-proxy-authentication-credential "AccessKeyId=ABCDE12345670EXAMPLE, RawSecretAccessKey=DXjSUawnel2fr6SKC7G25CNxTyWKE5PF9XX6H/u9pSo="

Output:
