Instance Method Detail
Returns true if this reference is the same as other. Invokes same?.
Skips ("bypasses") the key policy lockout safety check. The default value is false.
Setting this value to true increases the risk that the KMS key becomes unmanageable. Do not set this value to true indiscriminately.
For more information, see Default key policy in the Key Management Service Developer Guide.
Use this parameter only when you intend to prevent the principal that is making the request from making a subsequent PutKeyPolicy request on the KMS key.

Creates the KMS key in the specified custom key
store. The
ConnectionState of the custom key store must be CONNECTED. To find the CustomKeyStoreID and
ConnectionState use the DescribeCustomKeyStores operation.
This parameter is valid only for symmetric encryption KMS keys in a single Region. You cannot create any other type of KMS key in a custom key store.
When you create a KMS key in an CloudHSM key store, KMS generates a non-exportable 256-bit
symmetric key in its associated CloudHSM cluster and associates it with the KMS key. When you
create a KMS key in an external key store, you must use the XksKeyId parameter to specify an
external key that serves as key material for the KMS key.

Instead, use the KeySpec parameter.
The KeySpec and CustomerMasterKeySpec parameters work the same way. Only the names differ.
We recommend that you use KeySpec parameter in your code. However, to avoid breaking changes,
KMS supports both parameters.

Specifies the type of KMS key to create. The default value, SYMMETRIC_DEFAULT, creates a KMS
key with a 256-bit AES-GCM key that is used for encryption and decryption, except in China
Regions, where it creates a 128-bit symmetric key that uses SM4 encryption. For a detailed
description of all supported key specs, see Key spec
reference
in the * Key Management Service Developer Guide *.
The KeySpec determines whether the KMS key contains a symmetric key or an asymmetric key pair.
It also determines the algorithms that the KMS key supports. You can't change the KeySpec
after the KMS key is created. To further restrict the algorithms that can be used with the KMS
key, use a condition key in its key policy or IAM policy. For more information, see
kms:EncryptionAlgorithm,
kms:MacAlgorithm,
kms:KeyAgreementAlgorithm,
or
kms:SigningAlgorithm

Determines the cryptographic
operations
for which you can use the KMS key. The default value is ENCRYPT_DECRYPT. This parameter is
optional when you are creating a symmetric encryption KMS key; otherwise, it is required. You
can't change the KeyUsage
value after
the KMS key is created. Each KMS key can have only one key usage. This follows key usage best
practices according to NIST SP 800-57 Recommendations for Key
Management, section 5.2, Key usage.

Creates a multi-Region primary key that you can replicate into other Amazon Web Services Regions. You cannot change this value after you create the KMS key.
For a multi-Region key, set this parameter to True. For a single-Region KMS key, omit this
parameter or set it to False. The default value is False.
This operation supports multi-Region keys, an KMS feature that lets you create multiple interoperable KMS keys in different Amazon Web Services Regions. Because these KMS keys have the same key ID, key material, and other metadata, you can use them interchangeably to encrypt data in one Amazon Web Services Region and decrypt it in a different Amazon Web Services Region without re-encrypting the data or making a cross-Region call. For more information about multi-Region keys, see Multi-Region keys in KMS in the Key Management Service Developer Guide.
This value creates a primary key, not a replica. To create a replica key, use the ReplicateKey operation.
You can create a symmetric or asymmetric multi-Region key, and you can create a multi-Region key with imported key material. However, you cannot create a multi-Region key in a custom key store.

The source of the key material for the KMS key. You cannot change the origin after you create
the KMS key. The default is AWS_KMS, which means that KMS creates the key material.
To create a KMS key with no key
material
(for imported key material), set this value to EXTERNAL. For more information about importing
key material into KMS, see Importing Key
Material in the Key
Management Service Developer Guide. The EXTERNAL origin value is valid only for symmetric KMS
keys.
To create a KMS key in an CloudHSM key
store and
create its key material in the associated CloudHSM cluster, set this value to AWS_CLOUDHSM.
You must also use the CustomKeyStoreId parameter to identify the CloudHSM key store. The
KeySpec value must be SYMMETRIC_DEFAULT.
To create a KMS key in an external key
store, set this
value to EXTERNAL_KEY_STORE. You must also use the CustomKeyStoreId parameter to identify
the external key store and the XksKeyId parameter to identify the associated external key. The
KeySpec value must be SYMMETRIC_DEFAULT.

The key policy to attach to the KMS key.
If you provide a key policy, it must meet the following criteria:
-
The key policy must allow the calling principal to make a subsequent
PutKeyPolicyrequest on the KMS key. This reduces the risk that the KMS key becomes unmanageable. For more information, see Default key policy in the Key Management Service Developer Guide. (To omit this condition, setBypassPolicyLockoutSafetyCheckto true.) -
Each statement in the key policy must contain one or more principals. The principals in the key policy must exist and be visible to KMS. When you create a new Amazon Web Services principal, you might need to enforce a delay before including the new principal in a key policy because the new principal might not be immediately visible to KMS. For more information, see Changes that I make are not always immediately visible in the Amazon Web Services Identity and Access Management User Guide.
If either of the required Resource or Action elements are missing from a key policy
statement, the policy statement has no effect. When a key policy statement is missing one of
these elements, the KMS console correctly reports an error, but the CreateKey and
PutKeyPolicy API requests succeed, even though the policy statement is ineffective.
For more information on required key policy elements, see Elements in a key policy in the Key Management Service Developer Guide.
If you do not provide a key policy, KMS attaches a default key policy to the KMS key. For more information, see Default key policy in the Key Management Service Developer Guide.
If the key policy exceeds the length constraint, KMS returns a LimitExceededException.

Assigns one or more tags to the KMS key. Use this parameter to tag the KMS key when it is created. To tag an existing KMS key, use the TagResource operation.
Do not include confidential or sensitive information in this field. This field may be displayed in plaintext in CloudTrail logs and other output.
Tagging or untagging a KMS key can allow or deny permission to the KMS key. For details, see ABAC for KMS in the Key Management Service Developer Guide.
To use this parameter, you must have kms:TagResource permission in an IAM policy.
Each tag consists of a tag key and a tag value. Both the tag key and the tag value are required, but the tag value can be an empty (null) string. You cannot have more than one tag on a KMS key with the same tag key. If you specify an existing tag key with a different tag value, KMS replaces the current tag value with the specified one.
When you add tags to an Amazon Web Services resource, Amazon Web Services generates a cost allocation report with usage and costs aggregated by tags. Tags can also be used to control access to a KMS key. For details, see Tags in KMS.

Identifies the external key that serves as key material for the KMS key in an external key store. Specify the ID that the external key store proxy uses to refer to the external key. For help, see the documentation for your external key store proxy.
This parameter is required for a KMS key with an Origin value of EXTERNAL_KEY_STORE. It is
not valid for KMS keys with any other Origin value.
The external key must be an existing 256-bit AES symmetric encryption key hosted outside of
Amazon Web Services in an external key manager associated with the external key store specified
by the CustomKeyStoreId parameter. This key must be enabled and configured to perform
encryption and decryption. Each KMS key in an external key store must use a different external
key. For details, see Requirements for a KMS key in an external key
store
in the Key Management Service Developer Guide.
Each KMS key in an external key store is associated two backing keys. One is key material that KMS generates. The other is the external key specified by this parameter. When you use the KMS key in an external key store to encrypt data, the encryption operation is performed first by KMS using the KMS key material, and then by the external key manager using the specified external key, a process known as double encryption. For details, see Double encryption in the Key Management Service Developer Guide.
