getKeyPolicy
Description copied from interface:CfnKeyProps
The key policy that authorizes use of the KMS key. The key policy must conform to the following rules.- The key policy must allow the caller 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 AWS 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 AWS KMS . When you create a new AWS 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 AWS KMS . For more information, see Changes that I make are not always immediately visible in the AWS Identity and Access Management User Guide .
If you are unsure of which policy to use, consider the default key policy . This is the key policy that AWS KMS applies to KMS keys that are created by using the CreateKey API with no specified key policy. It gives the AWS account that owns the key permission to perform all operations on the key. It also allows you write IAM policies to authorize access to the key. For details, see Default key policy in the AWS Key Management Service Developer Guide .
A key policy document can include only the following characters:
- Printable ASCII characters
- Printable characters in the Basic Latin and Latin-1 Supplement character set
- The tab (
\ u0009
), line feed (\ u000A
), and carriage return (\ u000D
) special characters

getEnabled
Description copied from interface:CfnKeyProps
Specifies whether the KMS key is enabled. Disabled KMS keys cannot be used in cryptographic operations.When
Enabled
istrue
, the key state of the KMS key isEnabled
. WhenEnabled
isfalse
, the key state of the KMS key isDisabled
. The default value istrue
.The actual key state of the KMS key might be affected by actions taken outside of CloudFormation, such as running the EnableKey , DisableKey , or ScheduleKeyDeletion operations.
For information about the key states of a KMS key, see Key state: Effect on your KMS key in the AWS Key Management Service Developer Guide .

getEnableKeyRotation
Description copied from interface:CfnKeyProps
Enables automatic rotation of the key material for the specified KMS key.By default, automatic key rotation is not enabled.
AWS KMS supports automatic rotation only for symmetric encryption KMS keys (
KeySpec
=SYMMETRIC_DEFAULT
). For asymmetric KMS keys and HMAC KMS keys, omit theEnableKeyRotation
property or set it tofalse
.To enable automatic key rotation of the key material for a multi-Region KMS key, set
EnableKeyRotation
totrue
on the primary key (created by usingAWS::KMS::Key
). AWS KMS copies the rotation status to all replica keys. For details, see Rotating multi-Region keys in the AWS Key Management Service Developer Guide .When you enable automatic rotation, AWS KMS automatically creates new key material for the KMS key one year after the enable date and every year thereafter. AWS KMS retains all key material until you delete the KMS key. For detailed information about automatic key rotation, see Rotating KMS keys in the AWS Key Management Service Developer Guide .
- Specified by:
getEnableKeyRotation
in interfaceCfnKeyProps
-
getKeySpec
Description copied from interface:CfnKeyProps
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. In China Regions,SYMMETRIC_DEFAULT
creates a 128-bit symmetric key that uses SM4 encryption. You can't change theKeySpec
value after the KMS key is created. For help choosing a key spec for your KMS key, see Choosing a KMS key type in the AWS Key Management Service Developer Guide .The
KeySpec
property determines the type of key material in the KMS key and the algorithms that the KMS key supports. 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 AWS KMS condition keys in the AWS Key Management Service Developer Guide .If you change the value of the
KeySpec
property on an existing KMS key, the update request fails, regardless of the value of theUpdateReplacePolicy
attribute . This prevents you from accidentally deleting a KMS key by changing an immutable property value. > AWS services that are integrated with AWS KMS use symmetric encryption KMS keys to protect your data. These services do not support encryption with asymmetric KMS keys. For help determining whether a KMS key is asymmetric, see Identifying asymmetric KMS keys in the AWS Key Management Service Developer Guide .AWS KMS supports the following key specs for KMS keys:
- Symmetric encryption key (default)
SYMMETRIC_DEFAULT
(AES-256-GCM)- HMAC keys (symmetric)
HMAC_224
HMAC_256
HMAC_384
HMAC_512
- 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

getKeyUsage
Description copied from interface:CfnKeyProps
Determines the cryptographic operations for which you can use the KMS key. The default value isENCRYPT_DECRYPT
. This property is required for asymmetric KMS keys and HMAC KMS keys. You can't change theKeyUsage
value after the KMS key is created.If you change the value of the
KeyUsage
property on an existing KMS key, the update request fails, regardless of the value of theUpdateReplacePolicy
attribute . This prevents you from accidentally deleting a KMS key by changing an immutable property value.Select only one valid value.
- For symmetric encryption KMS keys, omit the property or specify
ENCRYPT_DECRYPT
. - For asymmetric KMS keys with RSA key material, specify
ENCRYPT_DECRYPT
orSIGN_VERIFY
. - For asymmetric KMS keys with ECC key material, specify
SIGN_VERIFY
. - For asymmetric KMS keys with SM2 (China Regions only) key material, specify
ENCRYPT_DECRYPT
orSIGN_VERIFY
. - For HMAC KMS keys, specify
GENERATE_VERIFY_MAC
.

getMultiRegion
Description copied from interface:CfnKeyProps
Creates a multi-Region primary key that you can replicate in other AWS Regions .You can't change the
MultiRegion
value after the KMS key is created.For a list of AWS Regions in which multi-Region keys are supported, see Multi-Region keys in AWS KMS in the ** .
If you change the value of the
MultiRegion
property on an existing KMS key, the update request fails, regardless of the value of theUpdateReplacePolicy
attribute . This prevents you from accidentally deleting a KMS key by changing an immutable property value.For a multi-Region key, set to this property to
true
. For a single-Region key, omit this property or set it tofalse
. The default value isfalse
.Multi-Region keys are an AWS KMS feature that lets you create multiple interoperable KMS keys in different AWS Regions . Because these KMS keys have the same key ID, key material, and other metadata, you can use them to encrypt data in one AWS Region and decrypt it in a different AWS Region without making a cross-Region call or exposing the plaintext data. For more information, see Multi-Region keys in the AWS Key Management Service Developer Guide .
You can create a symmetric encryption, HMAC, or asymmetric multi-Region KMS 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.
To create a replica of this primary key in a different AWS Region , create an AWS::KMS::ReplicaKey resource in a CloudFormation stack in the replica Region. Specify the key ARN of this primary key.

getPendingWindowInDays
Description copied from interface:CfnKeyProps
Specifies the number of days in the waiting period before AWS KMS deletes a KMS key that has been removed from a CloudFormation stack.Enter a value between 7 and 30 days. The default value is 30 days.
When you remove a KMS key from a CloudFormation stack, AWS KMS schedules the KMS key for deletion and starts the mandatory waiting period. The
PendingWindowInDays
property determines the length of waiting period. During the waiting period, the key state of KMS key isPending Deletion
orPending Replica Deletion
, which prevents the KMS key from being used in cryptographic operations. When the waiting period expires, AWS KMS permanently deletes the KMS key.AWS KMS will not delete a multi-Region primary key that has replica keys. If you remove a multi-Region primary key from a CloudFormation stack, its key state changes to
PendingReplicaDeletion
so it cannot be replicated or used in cryptographic operations. This state can persist indefinitely. When the last of its replica keys is deleted, the key state of the primary key changes toPendingDeletion
and the waiting period specified byPendingWindowInDays
begins. When this waiting period expires, AWS KMS deletes the primary key. For details, see Deleting multi-Region keys in the AWS Key Management Service Developer Guide .You cannot use a CloudFormation template to cancel deletion of the KMS key after you remove it from the stack, regardless of the waiting period. If you specify a KMS key in your template, even one with the same name, CloudFormation creates a new KMS key. To cancel deletion of a KMS key, use the AWS KMS console or the CancelKeyDeletion operation.
For information about the
Pending Deletion
andPending Replica Deletion
key states, see Key state: Effect on your KMS key in the AWS Key Management Service Developer Guide . For more information about deleting KMS keys, see the ScheduleKeyDeletion operation in the AWS Key Management Service API Reference and Deleting KMS keys in the AWS Key Management Service Developer Guide .Minimum : 7
