Paws::KMS - Perl Interface to AWS AWS Key Management Service
use Paws; my $obj = Paws->service('KMS'); my $res = $obj->Method( Arg1 => $val1, Arg2 => [ 'V1', 'V2' ], # if Arg3 is an object, the HashRef will be used as arguments to the constructor # of the arguments type Arg3 => { Att1 => 'Val1' }, # if Arg4 is an array of objects, the HashRefs will be passed as arguments to # the constructor of the arguments type Arg4 => [ { Att1 => 'Val1' }, { Att1 => 'Val2' } ], );
AWS Key Management Service
AWS Key Management Service (AWS KMS) is an encryption and key management web service. This guide describes the AWS KMS operations that you can call programmatically. For general information about AWS KMS, see the AWS Key Management Service Developer Guide (https://docs.aws.amazon.com/kms/latest/developerguide/).
AWS provides SDKs that consist of libraries and sample code for various programming languages and platforms (Java, Ruby, .Net, macOS, Android, etc.). The SDKs provide a convenient way to create programmatic access to AWS KMS and other AWS services. For example, the SDKs take care of tasks such as signing requests (see below), managing errors, and retrying requests automatically. For more information about the AWS SDKs, including how to download and install them, see Tools for Amazon Web Services (http://aws.amazon.com/tools/).
We recommend that you use the AWS SDKs to make programmatic API calls to AWS KMS.
Clients must support TLS (Transport Layer Security) 1.0. We recommend TLS 1.2. Clients must also support cipher suites with Perfect Forward Secrecy (PFS) such as Ephemeral Diffie-Hellman (DHE) or Elliptic Curve Ephemeral Diffie-Hellman (ECDHE). Most modern systems such as Java 7 and later support these modes.
Signing Requests
Requests must be signed by using an access key ID and a secret access key. We strongly recommend that you do not use your AWS account (root) access key ID and secret key for everyday work with AWS KMS. Instead, use the access key ID and secret access key for an IAM user. You can also use the AWS Security Token Service to generate temporary security credentials that you can use to sign requests.
All AWS KMS operations require Signature Version 4 (https://docs.aws.amazon.com/general/latest/gr/signature-version-4.html).
Logging API Requests
AWS KMS supports AWS CloudTrail, a service that logs AWS API calls and related events for your AWS account and delivers them to an Amazon S3 bucket that you specify. By using the information collected by CloudTrail, you can determine what requests were made to AWS KMS, who made the request, when it was made, and so on. To learn more about CloudTrail, including how to turn it on and find your log files, see the AWS CloudTrail User Guide (https://docs.aws.amazon.com/awscloudtrail/latest/userguide/).

Commonly Used API Operations
Of the API operations discussed in this guide, the following will prove the most useful for most applications. You will likely perform operations other than these, such as creating keys and assigning policies, by using the console.
Encrypt
Decrypt
GenerateDataKey
GenerateDataKeyWithoutPlaintext
For the AWS API documentation, see https://docs.aws.amazon.com/goto/WebAPI/kms-2014-11-01
Each argument is described in detail in: Paws::KMS::CancelKeyDeletion
Returns: a Paws::KMS::CancelKeyDeletionResponse instance
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.
Disabled
For more information about scheduling and canceling deletion of a CMK, see Deleting Customer Master Keys (https://docs.aws.amazon.com/kms/latest/developerguide/deleting-keys.html) 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 (https://docs.aws.amazon.com/kms/latest/developerguide/key-state.html) in the AWS Key Management Service Developer Guide.
Each argument is described in detail in: Paws::KMS::ConnectCustomKeyStore
Returns: a Paws::KMS::ConnectCustomKeyStoreResponse instance
Connects or reconnects a custom key store (https://docs.aws.amazon.com/kms/latest/developerguide/custom-key-store-overview.html) 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 (https://docs.aws.amazon.com/cloudhsm/latest/APIReference/API_DescribeClusters.html) operation. To add HSMs to the cluster, use the CreateHsm (https://docs.aws.amazon.com/cloudhsm/latest/APIReference/API_CreateHsm.html) 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 (https://docs.aws.amazon.com/kms/latest/developerguide/key-store-concepts.html#concept-kmsuser) (CU), and rotates its password.
kmsuser
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.
ConnectCustomKeyStore
ConnectionErrorCode
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 (https://docs.aws.amazon.com/kms/latest/developerguide/fix-keystore.html) in the AWS Key Management Service Developer Guide.
Each argument is described in detail in: Paws::KMS::CreateAlias
Returns: nothing
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 (https://docs.aws.amazon.com/kms/latest/developerguide/concepts.html#aws-managed-cmk).
alias/
alias/ExampleAlias
alias/aws/
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.
Each argument is described in detail in: Paws::KMS::CreateCustomKeyStore
Returns: a Paws::KMS::CreateCustomKeyStoreResponse instance
Creates a custom key store (https://docs.aws.amazon.com/kms/latest/developerguide/custom-key-store-overview.html) that is associated with an AWS CloudHSM cluster (https://docs.aws.amazon.com/cloudhsm/latest/userguide/clusters.html) that you own and manage.
This operation is part of the Custom Key Store feature (https://docs.aws.amazon.com/kms/latest/developerguide/custom-key-store-overview.html) 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 (https://docs.aws.amazon.com/kms/latest/developerguide/create-keystore.html#before-keystore) 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 (https://docs.aws.amazon.com/kms/latest/developerguide/fix-keystore.html) in the AWS Key Management Service Developer Guide.
Each argument is described in detail in: Paws::KMS::CreateGrant
Returns: a Paws::KMS::CreateGrantResponse instance
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.
Constraints
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 (https://docs.aws.amazon.com/kms/latest/developerguide/grants.html) in the AWS Key Management Service Developer Guide .
KeyId
Each argument is described in detail in: Paws::KMS::CreateKey
Returns: a Paws::KMS::CreateKeyResponse instance
Creates a customer managed customer master key (https://docs.aws.amazon.com/kms/latest/developerguide/concepts.html#master_keys) (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 (https://docs.aws.amazon.com/kms/latest/developerguide/concepts.html#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.
Origin
EXTERNAL
To create a CMK in a custom key store (https://docs.aws.amazon.com/kms/latest/developerguide/custom-key-store-overview.html), 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.
CustomKeyStoreId
AWS_CLOUDHSM
You cannot use this operation to create a CMK in a different AWS account.
Each argument is described in detail in: Paws::KMS::Decrypt
Returns: a Paws::KMS::DecryptResponse instance
Decrypts ciphertext. Ciphertext is plaintext that has been previously encrypted by using any of the following operations:
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.
Each argument is described in detail in: Paws::KMS::DeleteAlias
Deletes the specified alias. You cannot perform this operation on an alias in a different AWS account.
Each CMK can have multiple aliases. To change the alias of a CMK, use DeleteAlias to delete the current alias and CreateAlias to create a new alias. To associate an existing alias with a different customer master key (CMK), call UpdateAlias.
Each argument is described in detail in: Paws::KMS::DeleteCustomKeyStore
Returns: a Paws::KMS::DeleteCustomKeyStoreResponse instance
Deletes a custom key store (https://docs.aws.amazon.com/kms/latest/developerguide/custom-key-store-overview.html). 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) (https://docs.aws.amazon.com/kms/latest/developerguide/concepts.html#master_keys). 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 (https://docs.aws.amazon.com/kms/latest/developerguide/fix-keystore.html#fix-keystore-orphaned-key) from the cluster and its backups.
ScheduleKeyDeletion
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.
Each argument is described in detail in: Paws::KMS::DeleteImportedKeyMaterial
Deletes key material that you previously imported. This operation makes the specified customer master key (CMK) unusable. For more information about importing key material into AWS KMS, see Importing Key Material (https://docs.aws.amazon.com/kms/latest/developerguide/importing-keys.html) 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.
PendingDeletion
PendingImport
After you delete key material, you can use ImportKeyMaterial to reimport the same key material into the CMK.
Each argument is described in detail in: Paws::KMS::DescribeCustomKeyStores
Returns: a Paws::KMS::DescribeCustomKeyStoresResponse instance
Gets information about custom key stores (https://docs.aws.amazon.com/kms/latest/developerguide/custom-key-store-overview.html) in the account and region.
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).
CustomKeyStoreName
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.
ConnectionState
FAILED
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.
DISCONNECTED
CONNECTED
For help repairing your custom key store, see the Troubleshooting Custom Key Stores (https://docs.aws.amazon.com/kms/latest/developerguide/fix-keystore.html) topic in the AWS Key Management Service Developer Guide.
Each argument is described in detail in: Paws::KMS::DescribeKey
Returns: a Paws::KMS::DescribeKeyResponse instance
Provides detailed information about the specified customer master key (CMK).
You can use DescribeKey on a predefined AWS alias, that is, an AWS alias with no key ID. When you do, AWS KMS associates the alias with an AWS managed CMK (https://docs.aws.amazon.com/kms/latest/developerguide/concepts.html#master_keys) and returns its KeyId and Arn in the response.
DescribeKey
Arn
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.
Each argument is described in detail in: Paws::KMS::DisableKey
Sets the state of a customer master key (CMK) to disabled, thereby preventing its use for cryptographic operations. You cannot perform this operation on a CMK in a different AWS account.
For more information about how key state affects the use of a CMK, see How Key State Affects the Use of a Customer Master Key (https://docs.aws.amazon.com/kms/latest/developerguide/key-state.html) in the AWS Key Management Service Developer Guide .
Each argument is described in detail in: Paws::KMS::DisableKeyRotation
Disables automatic rotation of the key material (https://docs.aws.amazon.com/kms/latest/developerguide/rotate-keys.html) for the specified customer master key (CMK). You cannot perform this operation on a CMK in a different AWS account.
Each argument is described in detail in: Paws::KMS::DisconnectCustomKeyStore
Returns: a Paws::KMS::DisconnectCustomKeyStoreResponse instance
Disconnects the custom key store (https://docs.aws.amazon.com/kms/latest/developerguide/custom-key-store-overview.html) from its associated AWS CloudHSM cluster. While a custom key store is disconnected, you can manage the custom key store and its customer master keys (CMKs), but you cannot create or use CMKs in the custom key store. You can reconnect the custom key store at any time.
While a custom key store is disconnected, all attempts to create customer master keys (CMKs) in the custom key store or to use existing CMKs in cryptographic operations will fail. This action can prevent users from storing and accessing sensitive data.
To find the connection state of a custom key store, use the DescribeCustomKeyStores operation. To reconnect a custom key store, use the ConnectCustomKeyStore operation.
Each argument is described in detail in: Paws::KMS::EnableKey
Sets the key state of a customer master key (CMK) to enabled. This allows you to use the CMK for cryptographic operations. You cannot perform this operation on a CMK in a different AWS account.
Each argument is described in detail in: Paws::KMS::EnableKeyRotation
Enables automatic rotation of the key material (https://docs.aws.amazon.com/kms/latest/developerguide/rotate-keys.html) for the specified customer master key (CMK). You cannot perform this operation on a CMK in a different AWS account.
You cannot enable automatic rotation of CMKs with imported key material or CMKs in a custom key store (https://docs.aws.amazon.com/kms/latest/developerguide/custom-key-store-overview.html).
Each argument is described in detail in: Paws::KMS::Encrypt
Returns: a Paws::KMS::EncryptResponse instance
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.
Each argument is described in detail in: Paws::KMS::GenerateDataKey
Returns: a Paws::KMS::GenerateDataKeyResponse instance
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.
KeySpec
NumberOfBytes
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.
Plaintext
CiphertextBlob
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 (https://docs.aws.amazon.com/kms/latest/developerguide/concepts.html#encrypt_context) in the AWS Key Management Service Developer Guide .
EncryptionContext
InvalidCiphertextException
Each argument is described in detail in: Paws::KMS::GenerateDataKeyWithoutPlaintext
Returns: a Paws::KMS::GenerateDataKeyWithoutPlaintextResponse instance
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.
Each argument is described in detail in: Paws::KMS::GenerateRandom
Returns: a Paws::KMS::GenerateRandomResponse instance
Returns a random byte string that is cryptographically secure.
By default, the random byte string is generated in AWS KMS. To generate the byte string in the AWS CloudHSM cluster that is associated with a custom key store (https://docs.aws.amazon.com/kms/latest/developerguide/custom-key-store-overview.html), specify the custom key store ID.
For more information about entropy and random number generation, see the AWS Key Management Service Cryptographic Details (https://d0.awsstatic.com/whitepapers/KMS-Cryptographic-Details.pdf) whitepaper.
Each argument is described in detail in: Paws::KMS::GetKeyPolicy
Returns: a Paws::KMS::GetKeyPolicyResponse instance
Gets a key policy attached to the specified customer master key (CMK). You cannot perform this operation on a CMK in a different AWS account.
Each argument is described in detail in: Paws::KMS::GetKeyRotationStatus
Returns: a Paws::KMS::GetKeyRotationStatusResponse instance
Gets a Boolean value that indicates whether automatic rotation of the key material (https://docs.aws.amazon.com/kms/latest/developerguide/rotate-keys.html) is enabled for the specified customer master key (CMK).
Disabled: The key rotation status does not change when you disable a CMK. However, while the CMK is disabled, AWS KMS does not rotate the backing key.
Pending deletion: While a CMK is pending deletion, its key rotation status is false and AWS KMS does not rotate the backing key. If you cancel the deletion, the original key rotation status is restored.
false
To perform this operation on a CMK in a different AWS account, specify the key ARN in the value of the KeyId parameter.
Each argument is described in detail in: Paws::KMS::GetParametersForImport
Returns: a Paws::KMS::GetParametersForImportResponse instance
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 (https://docs.aws.amazon.com/kms/latest/developerguide/importing-keys.html) 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.
GetParametersForImport
Each argument is described in detail in: Paws::KMS::ImportKeyMaterial
Returns: a Paws::KMS::ImportKeyMaterialResponse instance
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 (https://docs.aws.amazon.com/kms/latest/developerguide/importing-keys.html) 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.
Enabled
Each argument is described in detail in: Paws::KMS::ListAliases
Returns: a Paws::KMS::ListAliasesResponse instance
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.
ListAliases
aws/<service-name>
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 (https://docs.aws.amazon.com/kms/latest/developerguide/limits.html#aliases-limit).
TargetKeyId
Each argument is described in detail in: Paws::KMS::ListGrants
Returns: a Paws::KMS::ListGrantsResponse instance
Gets a list of all grants for the specified customer master key (CMK).
Each argument is described in detail in: Paws::KMS::ListKeyPolicies
Returns: a Paws::KMS::ListKeyPoliciesResponse instance
Gets the names of the key policies that are attached to a customer master key (CMK). This operation is designed to get policy names that you can use in a GetKeyPolicy operation. However, the only valid policy name is default. You cannot perform this operation on a CMK in a different AWS account.
default
Each argument is described in detail in: Paws::KMS::ListKeys
Returns: a Paws::KMS::ListKeysResponse instance
Gets a list of all customer master keys (CMKs) in the caller's AWS account and region.
Each argument is described in detail in: Paws::KMS::ListResourceTags
Returns: a Paws::KMS::ListResourceTagsResponse instance
Returns a list of all tags for the specified customer master key (CMK).
You cannot perform this operation on a CMK in a different AWS account.
Each argument is described in detail in: Paws::KMS::ListRetirableGrants
Returns a list of all grants for which the grant's RetiringPrincipal matches the one specified.
RetiringPrincipal
A typical use is to list all grants that you are able to retire. To retire a grant, use RetireGrant.
Each argument is described in detail in: Paws::KMS::PutKeyPolicy
Attaches a key policy to the specified customer master key (CMK). You cannot perform this operation on a CMK in a different AWS account.
For more information about key policies, see Key Policies (https://docs.aws.amazon.com/kms/latest/developerguide/key-policies.html) in the AWS Key Management Service Developer Guide.
Each argument is described in detail in: Paws::KMS::ReEncrypt
Returns: a Paws::KMS::ReEncryptResponse instance
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 (https://docs.aws.amazon.com/kms/latest/developerguide/key-policies.html) 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.

Each argument is described in detail in: Paws::KMS::RetireGrant
Retires a grant. To clean up, you can retire a grant when you're done using it. You should revoke a grant when you intend to actively deny operations that depend on it. The following are permitted to call this API:
The AWS account (root user) under which the grant was created
The RetiringPrincipal, if present in the grant
The GranteePrincipal, if RetireGrant is an operation specified in the grant
GranteePrincipal
RetireGrant
You must identify the grant to retire by its grant token or by a combination of the grant ID and the Amazon Resource Name (ARN) of the customer master key (CMK). A grant token is a unique variable-length base64-encoded string. A grant ID is a 64 character unique identifier of a grant. The CreateGrant operation returns both.
Each argument is described in detail in: Paws::KMS::RevokeGrant
Revokes the specified grant for the specified customer master key (CMK). You can revoke a grant to actively deny operations that depend on it.
Each argument is described in detail in: Paws::KMS::ScheduleKeyDeletion
Returns: a Paws::KMS::ScheduleKeyDeletionResponse instance
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 (https://docs.aws.amazon.com/kms/latest/developerguide/custom-key-store-overview.html), 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 (https://docs.aws.amazon.com/kms/latest/developerguide/fix-keystore.html#fix-keystore-orphaned-key) from the cluster and its backups.
For more information about scheduling a CMK for deletion, see Deleting Customer Master Keys (https://docs.aws.amazon.com/kms/latest/developerguide/deleting-keys.html) in the AWS Key Management Service Developer Guide.
Each argument is described in detail in: Paws::KMS::TagResource
Adds or edits tags for a customer master key (CMK). You cannot perform this operation on a CMK in a different AWS account.
Each 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.
You can only use a tag key once for each CMK. If you use the tag key again, AWS KMS replaces the current tag value with the specified value.
For information about the rules that apply to tag keys and tag values, see User-Defined Tag Restrictions (https://docs.aws.amazon.com/awsaccountbilling/latest/aboutv2/allocation-tag-restrictions.html) in the AWS Billing and Cost Management User Guide.
Each argument is described in detail in: Paws::KMS::UntagResource
Removes the specified tags from the specified customer master key (CMK). You cannot perform this operation on a CMK in a different AWS account.
To remove a tag, specify the tag key. To change the tag value of an existing tag key, use TagResource.
Each argument is described in detail in: Paws::KMS::UpdateAlias
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.
Each argument is described in detail in: Paws::KMS::UpdateCustomKeyStore
Returns: a Paws::KMS::UpdateCustomKeyStoreResponse instance
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.
UpdateCustomKeyStore
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) (https://docs.aws.amazon.com/kms/latest/developerguide/key-store-concepts.html#concept-kmsuser) in the associated AWS CloudHSM cluster. You can use this parameter to fix connection failures (https://docs.aws.amazon.com/kms/latest/developerguide/fix-keystore.html#fix-keystore-password) 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.
Each argument is described in detail in: Paws::KMS::UpdateKeyDescription
Updates the description of a customer master key (CMK). To see the description of a CMK, use DescribeKey.
