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.
See https://www.paws-r-sdk.com/docs/kms_create_custom_key_store/ for full documentation.

)[required] 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.
Do not include confidential or sensitive information in this field. This field may be displayed in plaintext in CloudTrail logs and other output.
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.
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.
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
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.
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.
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
connect_custom_key_store 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 the same 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.
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.
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.
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
update_custom_key_store operation to
provide the new credential to KMS.
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.
