Creates a unique customer managed KMS key in your Amazon Web Services account and Region.
Note
KMS is replacing the term customer master key (CMK) with KMS key and KMS key . The concept has not changed. To prevent breaking changes, KMS is keeping some variations of this term.
You can use the CreateKey operation to create symmetric or asymmetric KMS keys.
Symmetric KMS keys contain a 256-bit symmetric key that never leaves KMS unencrypted. To use the KMS key, you must call KMS. You can use a symmetric KMS key to encrypt and decrypt small amounts of data, but they are typically used to generate data keys and data keys pairs. For details, see GenerateDataKey and GenerateDataKeyPair.
Asymmetric KMS keys can contain an RSA key pair or an Elliptic Curve (ECC) key pair. The private key in an asymmetric KMS key never leaves KMS unencrypted. However, you can use the GetPublicKey operation to download the public key so it can be used outside of KMS. KMS keys with RSA key pairs can be used to encrypt or decrypt data or sign and verify messages (but not both). KMS keys with ECC key pairs can be used only to sign and verify messages.
For information about symmetric and asymmetric KMS keys, see Using Symmetric and Asymmetric KMS keys in the Key Management Service Developer Guide .
To create different types of KMS keys, use the following guidance:
Asymmetric KMS keys
To create an asymmetric KMS key, use the KeySpec parameter to specify the type of key material in the KMS key. Then, use the KeyUsage parameter to determine whether the KMS key will be used to encrypt and decrypt or sign and verify. You can't change these properties after the KMS key is created.
Symmetric KMS keys
When creating a symmetric KMS key, you don't need to specify the KeySpec or KeyUsage parameters. The default value for KeySpec , SYMMETRIC_DEFAULT , and the default value for KeyUsage , ENCRYPT_DECRYPT , are the only valid values for symmetric KMS keys.
Multi-Region primary keys Imported key material
To create a multi-Region primary key in the local Amazon Web Services Region, use the MultiRegion parameter with a value of True . To create a multi-Region replica key , that is, a KMS key with the same key ID and key material as a primary key, but in a different Amazon Web Services Region, use the ReplicateKey operation. To change a replica key to a primary key, and its primary key to a replica key, use the UpdatePrimaryRegion operation.
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 Using multi-Region keys in the Key Management Service Developer Guide .
You can create symmetric and asymmetric multi-Region keys and multi-Region keys with imported key material. You cannot create multi-Region keys in a custom key store.
To import your own key material, begin by creating a symmetric KMS key with no key material. To do this, use the Origin parameter of CreateKey with a value of EXTERNAL . Next, use GetParametersForImport operation to get a public key and import token, and use the public key to encrypt your key material. Then, use ImportKeyMaterial with your import token to import the key material. For step-by-step instructions, see Importing Key Material in the Key Management Service Developer Guide . You cannot import the key material into an asymmetric KMS key.
To create a multi-Region primary key with imported key material, use the Origin parameter of CreateKey with a value of EXTERNAL and the MultiRegion parameter with a value of True . To create replicas of the multi-Region primary key, use the ReplicateKey operation. For more information about multi-Region keys, see Using multi-Region keys in the Key Management Service Developer Guide .
Custom key store
To create a symmetric KMS key in a custom key store, use the CustomKeyStoreId parameter to specify the custom key store. You must also use the Origin parameter with a value of AWS_CLOUDHSM . The CloudHSM cluster that is associated with the custom key store must have at least two active HSMs in different Availability Zones in the Amazon Web Services Region.
You cannot create an asymmetric KMS key in a custom key store. For information about custom key stores in KMS see Using Custom Key Stores in the Key Management Service Developer Guide .
Cross-account use : No. You cannot use this operation to create a KMS key in a different Amazon Web Services account.
Required permissions : kms:CreateKey (IAM policy). To use the Tags parameter, kms:TagResource (IAM policy). For examples and information about related permissions, see Allow a user to create KMS keys in the Key Management Service Developer Guide .

)
string
The key policy to attach to the KMS key.
If you provide a key policy, it must meet the following criteria:
If you don't set BypassPolicyLockoutSafetyCheck to true, the key policy must allow the principal that is making the CreateKey request to make a subsequent PutKeyPolicy request on the KMS key. This reduces the risk that the KMS key becomes unmanageable. For more information, refer to the scenario in the Default Key Policy section of the Key Management Service Developer Guide .
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 (for example, an IAM user or role), 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 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 .
The key policy size quota is 32 kilobytes (32768 bytes).
For help writing and formatting a JSON policy document, see the IAM JSON Policy Reference in the Identity and Access Management User Guide .
string
A description of the KMS key.
Use a description that helps you decide whether the KMS key is appropriate for a task. The default value is an empty string (no description).
To set or change the description after the key is created, use UpdateKeyDescription.
string
Determines the cryptographic operations for which you can use the KMS key. The default value is ENCRYPT_DECRYPT . This parameter is required only for asymmetric KMS keys. You can't change the KeyUsage value after the KMS key is created.
Select only one valid value.
For symmetric KMS keys, omit the parameter or specify ENCRYPT_DECRYPT .
For asymmetric KMS keys with RSA key material, specify ENCRYPT_DECRYPT or SIGN_VERIFY .
For asymmetric KMS keys with ECC key material, specify SIGN_VERIFY .
string
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 will support both parameters.
string
Specifies the type of KMS key to create. The default value, SYMMETRIC_DEFAULT , creates a KMS key with a 256-bit symmetric key for encryption and decryption. For help choosing a key spec for your KMS key, see How to Choose Your KMS key Configuration 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 encryption algorithms or signing 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 or kms:Signing Algorithm in the Key Management Service Developer Guide .
Warning
Amazon Web Services services that are integrated with KMS use symmetric KMS keys to protect your data. These services do not support asymmetric KMS keys. For help determining whether a KMS key is symmetric or asymmetric, see Identifying Symmetric and Asymmetric KMS keys in the Key Management Service Developer Guide .
KMS supports the following key specs for KMS keys:
Symmetric key (default)
SYMMETRIC_DEFAULT (AES-256-GCM)
Asymmetric RSA key pairs
RSA_2048
RSA_3072
RSA_4096
Asymmetric NIST-recommended elliptic curve key pairs
ECC_NIST_P256 (secp256r1)
ECC_NIST_P384 (secp384r1)
ECC_NIST_P521 (secp521r1)
Other asymmetric elliptic curve key pairs
ECC_SECG_P256K1 (secp256k1), commonly used for cryptocurrencies.
string
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 the value to EXTERNAL . For more information about importing key material into KMS, see Importing Key Material in the Key Management Service Developer Guide . This value is valid only for symmetric KMS keys.
To create a KMS key in an KMS custom 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 custom key store. This value is valid only for symmetric KMS keys.
string
Creates the KMS key in the specified custom key store and the key material in its associated CloudHSM cluster. To create a KMS key in a custom key store, you must also specify the Origin parameter with a value of AWS_CLOUDHSM . The CloudHSM cluster that is associated with the custom key store must have at least two active HSMs, each in a different Availability Zone in the Region.
This parameter is valid only for symmetric KMS keys and regional KMS keys. You cannot create an asymmetric KMS key or a multi-Region key in a custom key store.
To find the ID of a custom key store, use the DescribeCustomKeyStores operation.
The response includes the custom key store ID and the ID of the CloudHSM cluster.
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.
boolean
A flag to indicate whether to bypass the key policy lockout safety check.
Warning
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, refer to the scenario in the Default Key Policy section in the Key Management Service Developer Guide .
Use this parameter only when you include a policy in the request and you intend to prevent the principal that is making the request from making a subsequent PutKeyPolicy request on the KMS key.
The default value is false.
list
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.
Note
Tagging or untagging a KMS key can allow or deny permission to the KMS key. For details, see Using ABAC in 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 Tagging Keys.
(dict) --
A key-value pair. A tag consists of a tag key and a tag value. Tag keys and tag values are both required, but tag values can be empty (null) strings.
For information about the rules that apply to tag keys and tag values, see User-Defined Tag Restrictions in the Amazon Web Services Billing and Cost Management User Guide .
TagKey (string) -- [REQUIRED]
The key of the tag.
TagValue (string) -- [REQUIRED]
The value of the tag.
boolean
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 Using multi-Region keys 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.

Provides detailed information about a KMS key. You can run DescribeKey on a customer managed key or an Amazon Web Services managed key.
This detailed information includes the key ARN, creation date (and deletion date, if applicable), the key state, and the origin and expiration date (if any) of the key material. It includes fields, like KeySpec , that help you distinguish symmetric from asymmetric KMS keys. It also provides information that is particularly important to asymmetric keys, such as the key usage (encryption or signing) and the encryption algorithms or signing algorithms that the KMS key supports. For KMS keys in custom key stores, it includes information about the custom key store, such as the key store ID and the CloudHSM cluster ID. For multi-Region keys, it displays the primary key and all related replica keys.
DescribeKey does not return the following information:
Aliases associated with the KMS key. To get this information, use ListAliases.
Whether automatic key rotation is enabled on the KMS key. To get this information, use GetKeyRotationStatus. Also, some key states prevent a KMS key from being automatically rotated. For details, see How Automatic Key Rotation Works in Key Management Service Developer Guide .
Tags on the KMS key. To get this information, use ListResourceTags.
Key policies and grants on the KMS key. To get this information, use GetKeyPolicy and ListGrants.
If you call the DescribeKey operation on a predefined Amazon Web Services alias , that is, an Amazon Web Services alias with no key ID, KMS creates an Amazon Web Services managed key. Then, it associates the alias with the new KMS key, and returns the KeyId and Arn of the new KMS key in the response.
Cross-account use : Yes. To perform this operation with a KMS key in a different Amazon Web Services account, specify the key ARN or alias ARN in the value of the KeyId parameter.

[REQUIRED]
Describes the specified KMS key.
If you specify a predefined Amazon Web Services alias (an Amazon Web Services alias with no key ID), KMS associates the alias with an Amazon Web Services managed key and returns its KeyId and Arn in the response.
To specify a KMS key, use its key ID, key ARN, alias name, or alias ARN. When using an alias name, prefix it with "alias/" . To specify a KMS key in a different Amazon Web Services account, you must use the key ARN or alias ARN.
For example:
Key ID: 1234abcd-12ab-34cd-56ef-1234567890ab
Key ARN: arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab
Alias name: alias/ExampleAlias
Alias ARN: arn:aws:kms:us-east-2:111122223333:alias/ExampleAlias
To get the key ID and key ARN for a KMS key, use ListKeys or DescribeKey. To get the alias name and alias ARN, use ListAliases.

PendingDeletionWindowInDays (integer) --
The waiting period before the primary key in a multi-Region key is deleted. This waiting period begins when the last of its replica keys is deleted. This value is present only when the KeyState of the KMS key is PendingReplicaDeletion . That indicates that the KMS key is the primary key in a multi-Region key, it is scheduled for deletion, and it still has existing replica keys.
When a single-Region KMS key or a multi-Region replica key is scheduled for deletion, its deletion date is displayed in the DeletionDate field. However, when the primary key in a multi-Region key is scheduled for deletion, its waiting period doesn't begin until all of its replica keys are deleted. This value displays that waiting period. When the last replica key in the multi-Region key is deleted, the KeyState of the scheduled primary key changes from PendingReplicaDeletion to PendingDeletion and the deletion date appears in the DeletionDate field.

Returns the public key of an asymmetric KMS key. Unlike the private key of a asymmetric KMS key, which never leaves KMS unencrypted, callers with kms:GetPublicKey permission can download the public key of an asymmetric KMS key. You can share the public key to allow others to encrypt messages and verify signatures outside of KMS. For information about symmetric and asymmetric KMS keys, see Using Symmetric and Asymmetric KMS keys in the Key Management Service Developer Guide .
You do not need to download the public key. Instead, you can use the public key within KMS by calling the Encrypt, ReEncrypt, or Verify operations with the identifier of an asymmetric KMS key. When you use the public key within KMS, you benefit from the authentication, authorization, and logging that are part of every KMS operation. You also reduce of risk of encrypting data that cannot be decrypted. These features are not effective outside of KMS. For details, see Special Considerations for Downloading Public Keys.
To help you use the public key safely outside of KMS, GetPublicKey returns important information about the public key in the response, including:
KeySpec: The type of key material in the public key, such as RSA_4096 or ECC_NIST_P521 .
KeyUsage: Whether the key is used for encryption or signing.
EncryptionAlgorithms or SigningAlgorithms: A list of the encryption algorithms or the signing algorithms for the key.
Although KMS cannot enforce these restrictions on external operations, it is crucial that you use this information to prevent the public key from being used improperly. For example, you can prevent a public signing key from being used encrypt data, or prevent a public key from being used with an encryption algorithm that is not supported by KMS. You can also avoid errors, such as using the wrong signing algorithm in a verification operation.
The KMS key that you use for this operation must be in a compatible key state. For details, see Key state: Effect on your KMS key in the Key Management Service Developer Guide .
Cross-account use : Yes. To perform this operation with a KMS key in a different Amazon Web Services account, specify the key ARN or alias ARN in the value of the KeyId parameter.

KeyId (string) --
The Amazon Resource Name ( key ARN ) of the asymmetric KMS key from which the public key was downloaded.
PublicKey (bytes) --
The exported public key.
The value is a DER-encoded X.509 public key, also known as SubjectPublicKeyInfo (SPKI), as defined in RFC 5280. When you use the HTTP API or the Amazon Web Services CLI, the value is Base64-encoded. Otherwise, it is not Base64-encoded.
CustomerMasterKeySpec (string) --
Instead, use the KeySpec field in the GetPublicKey response.
The KeySpec and CustomerMasterKeySpec fields have the same value. We recommend that you use the KeySpec field in your code. However, to avoid breaking changes, KMS will support both fields.
KeySpec (string) --
The type of the of the public key that was downloaded.
KeyUsage (string) --
The permitted use of the public key. Valid values are ENCRYPT_DECRYPT or SIGN_VERIFY .
This information is critical. If a public key with SIGN_VERIFY key usage encrypts data outside of KMS, the ciphertext cannot be decrypted.

Replicates a multi-Region key into the specified Region. This operation creates a multi-Region replica key based on a multi-Region primary key in a different Region of the same Amazon Web Services partition. You can create multiple replicas of a primary key, but each must be in a different Region. To create a multi-Region primary key, use the CreateKey operation.
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 Using multi-Region keys in the Key Management Service Developer Guide .
A replica key is a fully-functional KMS key that can be used independently of its primary and peer replica keys. A primary key and its replica keys share properties that make them interoperable. They have the same key ID and key material. They also have the same key spec, key usage, key material origin, and automatic key rotation status. KMS automatically synchronizes these shared properties among related multi-Region keys. All other properties of a replica key can differ, including its key policy, tags, aliases, and key state. KMS pricing and quotas for KMS keys apply to each primary key and replica key.
When this operation completes, the new replica key has a transient key state of Creating . This key state changes to Enabled (or PendingImport ) after a few seconds when the process of creating the new replica key is complete. While the key state is Creating , you can manage key, but you cannot yet use it in cryptographic operations. If you are creating and using the replica key programmatically, retry on KMSInvalidStateException or call DescribeKey to check its KeyState value before using it. For details about the Creating key state, see Key state: Effect on your KMS key in the Key Management Service Developer Guide .
The CloudTrail log of a ReplicateKey operation records a ReplicateKey operation in the primary key's Region and a CreateKey operation in the replica key's Region.
If you replicate a multi-Region primary key with imported key material, the replica key is created with no key material. You must import the same key material that you imported into the primary key. For details, see Importing key material into multi-Region keys in the Key Management Service Developer Guide .
To convert a replica key to a primary key, use the UpdatePrimaryRegion operation.
Note
ReplicateKey uses different default values for the KeyPolicy and Tags parameters than those used in the KMS console. For details, see the parameter descriptions.
Cross-account use : No. You cannot use this operation to create a replica key in a different Amazon Web Services account.
Required permissions :
kms:ReplicateKey on the primary key (in the primary key's Region). Include this permission in the primary key's key policy.
kms:CreateKey in an IAM policy in the replica Region.
To use the Tags parameter, kms:TagResource in an IAM policy in the replica Region.

[REQUIRED]
Identifies the multi-Region primary key that is being replicated. To determine whether a KMS key is a multi-Region primary key, use the DescribeKey operation to check the value of the MultiRegionKeyType property.
Specify the key ID or key ARN of a multi-Region primary key.
For example:
Key ID: mrk-1234abcd12ab34cd56ef1234567890ab
Key ARN: arn:aws:kms:us-east-2:111122223333:key/mrk-1234abcd12ab34cd56ef1234567890ab
To get the key ID and key ARN for a KMS key, use ListKeys or DescribeKey.
string
[REQUIRED]
The Region ID of the Amazon Web Services Region for this replica key.
Enter the Region ID, such as us-east-1 or ap-southeast-2 . For a list of Amazon Web Services Regions in which KMS is supported, see KMS service endpoints in the Amazon Web Services General Reference .
The replica must be in a different Amazon Web Services Region than its primary key and other replicas of that primary key, but in the same Amazon Web Services partition. KMS must be available in the replica Region. If the Region is not enabled by default, the Amazon Web Services account must be enabled in the Region.
For information about Amazon Web Services partitions, see Amazon Resource Names (ARNs) in the Amazon Web Services General Reference. For information about enabling and disabling Regions, see Enabling a Region and Disabling a Region in the Amazon Web Services General Reference .
string
The key policy to attach to the KMS key. This parameter is optional. If you do not provide a key policy, KMS attaches the default key policy to the KMS key.
The key policy is not a shared property of multi-Region keys. You can specify the same key policy or a different key policy for each key in a set of related multi-Region keys. KMS does not synchronize this property.
If you provide a key policy, it must meet the following criteria:
If you don't set BypassPolicyLockoutSafetyCheck to true, the key policy must give the caller kms:PutKeyPolicy permission on the replica key. This reduces the risk that the KMS key becomes unmanageable. For more information, refer to the scenario in the Default Key Policy section of the Key Management Service Developer Guide .
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 (for example, an IAM user or role), 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 Identity and Access Management User Guide .
The key policy size quota is 32 kilobytes (32768 bytes).
boolean
A flag to indicate whether to bypass the key policy lockout safety check.
Warning
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, refer to the scenario in the Default Key Policy section 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.
The default value is false.
string
A description of the KMS key. The default value is an empty string (no description).
The description is not a shared property of multi-Region keys. You can specify the same description or a different description for each key in a set of related multi-Region keys. KMS does not synchronize this property.
list
Assigns one or more tags to the replica key. Use this parameter to tag the KMS key when it is created. To tag an existing KMS key, use the TagResource operation.
Note
Tagging or untagging a KMS key can allow or deny permission to the KMS key. For details, see Using ABAC in KMS in the Key Management Service Developer Guide .
To use this parameter, you must have kms:TagResource permission in an IAM policy.
Tags are not a shared property of multi-Region keys. You can specify the same tags or different tags for each key in a set of related multi-Region keys. KMS does not synchronize this property.
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 Tagging Keys.
(dict) --
A key-value pair. A tag consists of a tag key and a tag value. Tag keys and tag values are both required, but tag values can be empty (null) strings.
For information about the rules that apply to tag keys and tag values, see User-Defined Tag Restrictions in the Amazon Web Services Billing and Cost Management User Guide .
