Cancels the deletion of a customer master key (CMK). When this operation is successful, the CMK is set to the Disabled state. To enable a CMK, use EnableKey. You cannot perform this operation on a CMK in a different AWS account.
For more information about scheduling and canceling deletion of a CMK, see Deleting Customer Master Keys in the AWS Key Management Service Developer Guide.
The result of this operation varies with the key state of the CMK. For details, see How Key State Affects Use of a Customer Master Key in the AWS Key Management Service Developer Guide.

Connects or reconnects a custom key store to its associated AWS CloudHSM cluster.
The custom key store must be connected before you can create customer master keys (CMKs) in the key store or use the CMKs it contains. You can disconnect and reconnect a custom key store at any time.
To connect a custom key store, its associated AWS CloudHSM cluster must have at least one active HSM. To get the number of active HSMs in a cluster, use the DescribeClusters operation. To add HSMs to the cluster, use the CreateHsm operation.
The connection process can take an extended amount of time to complete; up to 20 minutes. This operation starts the connection process, but it does not wait for it to complete. When it succeeds, this operation quickly returns an HTTP 200 response and a JSON object with no properties. However, this response does not indicate that the custom key store is connected. To get the connection state of the custom key store, use the DescribeCustomKeyStores operation.
During the connection process, AWS KMS finds the AWS CloudHSM cluster that is associated with the custom key store, creates the connection infrastructure, connects to the cluster, logs into the AWS CloudHSM client as the kmsuser crypto user (CU), and rotates its password.
The ConnectCustomKeyStore operation might fail for various reasons. To find the reason, use the DescribeCustomKeyStores operation and see the ConnectionErrorCode in the response. For help interpreting the ConnectionErrorCode, see CustomKeyStoresListEntry.
To fix the failure, use the DisconnectCustomKeyStore operation to disconnect the custom key store, correct the error, use the UpdateCustomKeyStore operation if necessary, and then use ConnectCustomKeyStore again.
If you are having trouble connecting or disconnecting a custom key store, see Troubleshooting a Custom Key Store in the AWS Key Management Service Developer Guide.

Creates a display name for a customer managed customer master key (CMK). You can use an alias to identify a CMK in selected operations, such as Encrypt and GenerateDataKey.
Each CMK can have multiple aliases, but each alias points to only one CMK. The alias name must be unique in the AWS account and region. To simplify code that runs in multiple regions, use the same alias name, but point it to a different CMK in each region.
Because an alias is not a property of a CMK, you can delete and change the aliases of a CMK without affecting the CMK. Also, aliases do not appear in the response from the DescribeKey operation. To get the aliases of all CMKs, use the ListAliases operation.
The alias name must begin with alias/ followed by a name, such as alias/ExampleAlias. It can contain only alphanumeric characters, forward slashes (/), underscores (_), and dashes (-). The alias name cannot begin with alias/aws/. The alias/aws/ prefix is reserved for AWS managed CMKs.
The alias and the CMK it is mapped to must be in the same AWS account and the same region. You cannot perform this operation on an alias in a different AWS account.
To map an existing alias to a different CMK, call UpdateAlias.
The result of this operation varies with the key state of the CMK. For details, see How Key State Affects Use of a Customer Master Key in the AWS Key Management Service Developer Guide.

Creates a custom key store that is associated with an AWS CloudHSM cluster that you own and manage.
This operation is part of the Custom Key Store feature feature in AWS KMS, which combines the convenience and extensive integration of AWS KMS with the isolation and control of a single-tenant key store.
Before you create the custom key store, you must assemble the required elements, including an AWS CloudHSM cluster that fulfills the requirements for a custom key store. For details about the required elements, see Assemble the Prerequisites in the AWS Key Management Service Developer Guide.
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 the new key store to its AWS CloudHSM cluster. 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 AWS Key Management Service Developer Guide.

Adds a grant to a customer master key (CMK). The grant allows the grantee principal to use the CMK when the conditions specified in the grant are met. When setting permissions, grants are an alternative to key policies.
To create a grant that allows a cryptographic operation only when the encryption context in the operation request matches or includes a specified encryption context, use the Constraints parameter. For details, see GrantConstraints.
To perform this operation on a CMK in a different AWS account, specify the key ARN in the value of the KeyId parameter. For more information about grants, see Grants in the AWS Key Management Service Developer Guide .

Creates a customer managed customer master key (CMK) in your AWS account.
You can use a CMK to encrypt small amounts of data (up to 4096 bytes) directly. But CMKs are more commonly used to encrypt the data keys that are used to encrypt data.
To create a CMK for imported key material, use the Origin parameter with a value of EXTERNAL.
To create a CMK 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 AWS CloudHSM cluster that is associated with the custom key store must have at least two active HSMs in different Availability Zones in the AWS Region.

Decrypts ciphertext. Ciphertext is plaintext that has been previously encrypted by using any of the following operations:
GenerateDataKey
GenerateDataKeyWithoutPlaintext
Encrypt
Whenever possible, use key policies to give users permission to call the Decrypt operation on the CMK, instead of IAM policies. Otherwise, you might create an IAM user policy that gives the user Decrypt permission on all CMKs. This user could decrypt ciphertext that was encrypted by CMKs in other accounts if the key policy for the cross-account CMK permits it. If you must use an IAM policy for Decrypt permissions, limit the user to particular CMKs or particular trusted accounts.

Deletes a custom key store. This operation does not delete the AWS CloudHSM cluster that is associated with the custom key store, or affect any users or keys in the cluster.
The custom key store that you delete cannot contain any AWS KMS customer master keys (CMKs). Before deleting the key store, verify that you will never need to use any of the CMKs in the key store for any cryptographic operations. Then, use ScheduleKeyDeletion to delete the AWS KMS customer master keys (CMKs) from the key store. When the scheduled waiting period expires, the ScheduleKeyDeletion operation deletes the CMKs. Then it makes a best effort to delete the key material from the associated cluster. However, you might need to manually delete the orphaned key material from the cluster and its backups.
After all CMKs are deleted from AWS KMS, use DisconnectCustomKeyStore to disconnect the key store from AWS KMS. Then, you can delete the custom key store.
Instead of deleting the custom key store, consider using DisconnectCustomKeyStore to disconnect it from AWS KMS. While the key store is disconnected, you cannot create or use the CMKs in the key store. But, you do not need to delete CMKs and you can reconnect a disconnected custom key store at any time.
If the operation succeeds, it returns a JSON object with no properties.

For more information about importing key material into AWS KMS, see Importing Key Material in the AWS Key Management Service Developer Guide. You cannot perform this operation on a CMK in a different AWS account.
When the specified CMK is in the PendingDeletion state, this operation does not change the CMK's state. Otherwise, it changes the CMK's state to PendingImport.
After you delete key material, you can use ImportKeyMaterial to reimport the same key material into the CMK.

Gets information about custom key stores in the account and region.
This operation is part of the Custom Key Store feature feature in AWS KMS, which combines the convenience and extensive integration of AWS KMS with the isolation and control of a single-tenant key store.
By default, this operation returns information about all custom key stores in the account and region. To get only information about a particular custom key store, use either the CustomKeyStoreName or CustomKeyStoreId parameter (but not both).
To determine whether the custom key store is connected to its AWS CloudHSM cluster, use the ConnectionState element in the response. If an attempt to connect the custom key store failed, the ConnectionState value is FAILED and the ConnectionErrorCode element in the response indicates the cause of the failure. For help interpreting the ConnectionErrorCode, see CustomKeyStoresListEntry.
Custom key stores have a DISCONNECTED connection state if the key store has never been connected or you use the DisconnectCustomKeyStore operation to disconnect it. If your custom key store state is CONNECTED but you are having trouble using it, make sure that its associated AWS CloudHSM cluster is active and contains the minimum number of HSMs required for the operation, if any.

Encrypts plaintext into ciphertext by using a customer master key (CMK). The Encrypt operation has two primary use cases:
You can encrypt up to 4 kilobytes (4096 bytes) of arbitrary data such as an RSA key, a database password, or other sensitive information.
You can use the Encrypt operation to move encrypted data from one AWS region to another. In the first region, generate a data key and use the plaintext key to encrypt the data. Then, in the new region, call the Encrypt method on same plaintext data key. Now, you can safely move the encrypted data and encrypted data key to the new region, and decrypt in the new region when necessary.
You don't need use this operation to encrypt a data key within a region. The GenerateDataKey and GenerateDataKeyWithoutPlaintext operations return an encrypted data key.
Also, you don't need to use this operation to encrypt data in your application. You can use the plaintext and encrypted data keys that the GenerateDataKey operation returns.
The result of this operation varies with the key state of the CMK. For details, see How Key State Affects Use of a Customer Master Key in the AWS Key Management Service Developer Guide.

Generates a unique data key. This operation returns a plaintext copy of the data key and a copy that is encrypted under a customer master key (CMK) that you specify. You can use the plaintext key to encrypt your data outside of KMS and store the encrypted data key with the encrypted data.
GenerateDataKey returns a unique data key for each request. The bytes in the key are not related to the caller or CMK that is used to encrypt the data key.
To generate a data key, you need to specify the customer master key (CMK) that will be used to encrypt the data key. You must also specify the length of the data key using either the KeySpec or NumberOfBytes field (but not both). For common key lengths (128-bit and 256-bit symmetric keys), we recommend that you use KeySpec. To perform this operation on a CMK in a different AWS account, specify the key ARN or alias ARN in the value of the KeyId parameter.
You will find the plaintext copy of the data key in the Plaintext field of the response, and the encrypted copy of the data key in the CiphertextBlob field.
We recommend that you use the following pattern to encrypt data locally in your application:
Use the GenerateDataKey operation to get a data encryption key.
Use the plaintext data key (returned in the Plaintext field of the response) to encrypt data locally, then erase the plaintext data key from memory.
Store the encrypted data key (returned in the CiphertextBlob field of the response) alongside the locally encrypted data.
To decrypt data locally:
Use the Decrypt operation to decrypt the encrypted data key. The operation returns a plaintext copy of the data key.
Use the plaintext data key to decrypt data locally, then erase the plaintext data key from memory.
To get only an encrypted copy of the data key, use GenerateDataKeyWithoutPlaintext. To get a cryptographically secure random byte string, use GenerateRandom.
You can use the optional encryption context to add additional security to your encryption operation. When you specify an EncryptionContext in the GenerateDataKey operation, you must specify the same encryption context (a case-sensitive exact match) in your request to Decrypt the data key. Otherwise, the request to decrypt fails with an InvalidCiphertextException. For more information, see Encryption Context in the AWS Key Management Service Developer Guide .
The result of this operation varies with the key state of the CMK. For details, see How Key State Affects Use of a Customer Master Key in the AWS Key Management Service Developer Guide.

Generates a unique data key. This operation returns a data key that is encrypted under a customer master key (CMK) that you specify. GenerateDataKeyWithoutPlaintext is identical to GenerateDataKey except that returns only the encrypted copy of the data key.
Like GenerateDataKey, GenerateDataKeyWithoutPlaintext returns a unique data key for each request. The bytes in the key are not related to the caller or CMK that is used to encrypt the data key.
This operation is useful for systems that need to encrypt data at some point, but not immediately. When you need to encrypt the data, you call the Decrypt operation on the encrypted copy of the key.
It's also useful in distributed systems with different levels of trust. For example, you might store encrypted data in containers. One component of your system creates new containers and stores an encrypted data key with each container. Then, a different component puts the data into the containers. That component first decrypts the data key, uses the plaintext data key to encrypt data, puts the encrypted data into the container, and then destroys the plaintext data key. In this system, the component that creates the containers never sees the plaintext data key.
The result of this operation varies with the key state of the CMK. For details, see How Key State Affects Use of a Customer Master Key in the AWS Key Management Service Developer Guide.

Returns the items you need in order to import key material into AWS KMS from your existing key management infrastructure. For more information about importing key material into AWS KMS, see Importing Key Material in the AWS Key Management Service Developer Guide.
You must specify the key ID of the customer master key (CMK) into which you will import key material. This CMK's Origin must be EXTERNAL. You must also specify the wrapping algorithm and type of wrapping key (public key) that you will use to encrypt the key material. You cannot perform this operation on a CMK in a different AWS account.
This operation returns a public key and an import token. Use the public key to encrypt the key material. Store the import token to send with a subsequent ImportKeyMaterial request. The public key and import token from the same response must be used together. These items are valid for 24 hours. When they expire, they cannot be used for a subsequent ImportKeyMaterial request. To get new ones, send another GetParametersForImport request.

Imports key material into an existing AWS KMS customer master key (CMK) that was created without key material. You cannot perform this operation on a CMK in a different AWS account. For more information about creating CMKs with no key material and then importing key material, see Importing Key Material in the AWS Key Management Service Developer Guide.
Before using this operation, call GetParametersForImport. Its response includes a public key and an import token. Use the public key to encrypt the key material. Then, submit the import token from the same GetParametersForImport response.
When calling this operation, you must specify the following values:
The key ID or key ARN of a CMK with no key material. Its Origin must be EXTERNAL. To create a CMK with no key material, call CreateKey and set the value of its Origin parameter to EXTERNAL. To get the Origin of a CMK, call DescribeKey.)
The encrypted key material. To get the public key to encrypt the key material, call GetParametersForImport.
The import token that GetParametersForImport returned. This token and the public key used to encrypt the key material must have come from the same response.
Whether the key material expires and if so, when. If you set an expiration date, you can change it only by reimporting the same key material and specifying a new expiration date. If the key material expires, AWS KMS deletes the key material and the CMK becomes unusable. To use the CMK again, you must reimport the same key material.
When this operation is successful, the key state of the CMK changes from PendingImport to Enabled, and you can use the CMK. After you successfully import key material into a CMK, you can reimport the same key material into that CMK, but you cannot import different key material.

Gets a list of aliases in the caller's AWS account and region. You cannot list aliases in other accounts. For more information about aliases, see CreateAlias.
By default, the ListAliases command returns all aliases in the account and region. To get only the aliases that point to a particular customer master key (CMK), use the KeyId parameter.
The ListAliases response can include aliases that you created and associated with your customer managed CMKs, and aliases that AWS created and associated with AWS managed CMKs in your account. You can recognize AWS aliases because their names have the format aws/<service-name>, such as aws/dynamodb.
The response might also include aliases that have no TargetKeyId field. These are predefined aliases that AWS has created but has not yet associated with a CMK. Aliases that AWS creates in your account, including predefined aliases, do not count against your AWS KMS aliases limit.

Encrypts data on the server side with a new customer master key (CMK) without exposing the plaintext of the data on the client side. The data is first decrypted and then reencrypted. You can also use this operation to change the encryption context of a ciphertext.
You can reencrypt data using CMKs in different AWS accounts.
Unlike other operations, ReEncrypt is authorized twice, once as ReEncryptFrom on the source CMK and once as ReEncryptTo on the destination CMK. We recommend that you include the "kms:ReEncrypt*" permission in your key policies to permit reencryption from or to the CMK. This permission is automatically included in the key policy when you create a CMK through the console. But you must include it manually when you create a CMK programmatically or when you set a key policy with the PutKeyPolicy operation.

Schedules the deletion of a customer master key (CMK). You may provide a waiting period, specified in days, before deletion occurs. If you do not provide a waiting period, the default period of 30 days is used. When this operation is successful, the key state of the CMK changes to PendingDeletion. Before the waiting period ends, you can use CancelKeyDeletion to cancel the deletion of the CMK. After the waiting period ends, AWS KMS deletes the CMK and all AWS KMS data associated with it, including all aliases that refer to it.
Deleting a CMK is a destructive and potentially dangerous operation. When a CMK is deleted, all data that was encrypted under the CMK is unrecoverable. To prevent the use of a CMK without deleting it, use DisableKey.
If you schedule deletion of a CMK from a custom key store, when the waiting period expires, ScheduleKeyDeletion deletes the CMK from AWS KMS. Then AWS KMS makes a best effort to delete the key material from the associated AWS CloudHSM cluster. However, you might need to manually delete the orphaned key material from the cluster and its backups.
You cannot perform this operation on a CMK in a different AWS account.
For more information about scheduling a CMK for deletion, see Deleting Customer Master Keys in the AWS Key Management Service Developer Guide.

Associates an existing alias with a different customer master key (CMK). Each CMK can have multiple aliases, but the aliases must be unique within the account and region. You cannot perform this operation on an alias in a different AWS account.
This operation works only on existing aliases. To change the alias of a CMK to a new value, use CreateAlias to create a new alias and DeleteAlias to delete the old alias.
Because an alias is not a property of a CMK, you can create, update, and delete the aliases of a CMK without affecting the CMK. Also, aliases do not appear in the response from the DescribeKey operation. To get the aliases of all CMKs in the account, use the ListAliases operation.
The alias name must begin with alias/ followed by a name, such as alias/ExampleAlias. It can contain only alphanumeric characters, forward slashes (/), underscores (_), and dashes (-). The alias name cannot begin with alias/aws/. The alias/aws/ prefix is reserved for AWS managed CMKs.
The result of this operation varies with the key state of the CMK. For details, see How Key State Affects Use of a Customer Master Key in the AWS Key Management Service Developer Guide.

Changes the properties of a custom key store. Use the CustomKeyStoreId parameter to identify the custom key store you want to edit. Use the remaining parameters to change the properties of the custom key store.
You can only update a custom key store that is disconnected. To disconnect the custom key store, use DisconnectCustomKeyStore. To reconnect the custom key store after the update completes, use ConnectCustomKeyStore. To find the connection state of a custom key store, use the DescribeCustomKeyStores operation.
Use the parameters of UpdateCustomKeyStore to edit your keystore settings.
Use the NewCustomKeyStoreName parameter to change the friendly name of the custom key store to the value that you specify.
Use the KeyStorePassword parameter tell AWS KMS the current password of the kmsuser crypto user (CU) in the associated AWS CloudHSM cluster. You can use this parameter to fix connection failures that occur when AWS KMS cannot log into the associated cluster because the kmsuser password has changed. This value does not change the password in the AWS CloudHSM cluster.
Use the CloudHsmClusterId parameter to associate the custom key store with a different, but related, AWS CloudHSM cluster. You can use this parameter to repair a custom key store if its AWS CloudHSM cluster becomes corrupted or is deleted, or when you need to create or restore a cluster from a backup.
If the operation succeeds, it returns a JSON object with no properties.
This operation is part of the Custom Key Store feature feature in AWS KMS, which combines the convenience and extensive integration of AWS KMS with the isolation and control of a single-tenant key store.

In addition, the replacement cluster must fulfill the requirements for a cluster associated with a custom key store. To view the cluster certificate of a cluster, use the DescribeClusters operation."

Updates the description of a customer master key (CMK). To see the description of a CMK, use DescribeKey.
You cannot perform this operation on a CMK in a different AWS account.
The result of this operation varies with the key state of the CMK. For details, see How Key State Affects Use of a Customer Master Key in the AWS Key Management Service Developer Guide.
