Overview

Package kms provides the API client, operations, and parameter types for AWS Key Management Service.

Key Management Service

Key Management Service (KMS) is an encryption and key management web service. This guide describes the KMS operations that you can call programmatically. For general information about KMS, see the Key Management Service Developer Guide.

KMS has replaced 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.

Amazon Web Services 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 KMS and other Amazon Web Services 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 Amazon Web Services SDKs, including how to download and install them, see Tools for Amazon Web Services.

We recommend that you use the Amazon Web Services SDKs to make programmatic API calls to KMS.

If you need to use FIPS 140-2 validated cryptographic modules when communicating with Amazon Web Services, use the FIPS endpoint in your preferred Amazon Web Services Region. For more information about the available FIPS endpoints, see endpoints[https://docs.aws.amazon.com/general/latest/gr/kms.html#kms_region]in the Key Management Service topic of the Amazon Web Services General Reference.

All KMS API calls must be signed and be transmitted using Transport Layer Security (TLS). KMS recommends you always use the latest supported TLS version. 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 using an access key ID and a secret access key. We strongly recommend that you do not use your Amazon Web Services account root access key ID and secret access key for everyday work. You can use the access key ID and secret access key for an IAM user or you can use the Security Token Service (STS) to generate temporary security credentials and use those to sign requests.

All KMS requests must be signed with Signature Version 4.

Logging API Requests

KMS supports CloudTrail, a service that logs Amazon Web Services API calls and related events for your Amazon Web Services 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 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 CloudTrail User Guide.

CreateCustomKeyStoreInput struct

Structure Fields:

CustomKeyStoreName *string

Specifies a friendly name for the custom key store. The name must be unique in your Amazon Web Services account and Region. This parameter is required for all custom key stores.

Do not include confidential or sensitive information in this field. This field may be displayed in plaintext in CloudTrail logs and other output.

This member is required.

CloudHsmClusterId *string

Identifies the CloudHSM cluster for an CloudHSM key store. This parameter is required for custom key stores with CustomKeyStoreType of AWS_CLOUDHSM .

Enter the cluster ID of any active CloudHSM cluster that is not already associated with a custom key store. To find the cluster ID, use the DescribeClusters[https://docs.aws.amazon.com/cloudhsm/latest/APIReference/API_DescribeClusters.html]operation.

CustomKeyStoreType types.CustomKeyStoreType

Specifies the type of custom key store. The default value is AWS_CLOUDHSM .

For a custom key store backed by an CloudHSM cluster, omit the parameter or enter AWS_CLOUDHSM . For a custom key store backed by an external key manager outside of Amazon Web Services, enter EXTERNAL_KEY_STORE . You cannot change this property after the key store is created.

KeyStorePassword *string

Specifies the kmsuser password for an CloudHSM key store. This parameter is required for custom key stores with a CustomKeyStoreType of AWS_CLOUDHSM .

Enter the password of the crypto user (CU) account[https://docs.aws.amazon.com/kms/latest/developerguide/key-store-concepts.html#concept-kmsuser]kmsuser in the specified CloudHSM cluster. KMS logs into the cluster as this user to manage key material on your behalf.

The password must be a string of 7 to 32 characters. Its value is case sensitive.

This parameter tells KMS the kmsuser account password; it does not change the password in the CloudHSM cluster.

TrustAnchorCertificate *string

Specifies the certificate for an CloudHSM key store. This parameter is required for custom key stores with a CustomKeyStoreType of AWS_CLOUDHSM .

Enter the content of the trust anchor certificate for the CloudHSM cluster. This is the content of the customerCA.crt file that you created when you initialized the cluster.

XksProxyAuthenticationCredential *types.XksProxyAuthenticationCredentialType

Specifies an authentication credential for the external key store proxy (XKS proxy). This parameter is required for all custom key stores with a CustomKeyStoreType of EXTERNAL_KEY_STORE .

The XksProxyAuthenticationCredential has two required elements: RawSecretAccessKey , a secret key, and AccessKeyId , a unique identifier for the RawSecretAccessKey . For character requirements, see XksProxyAuthenticationCredentialType.

KMS uses this authentication credential to sign requests to the external key store proxy on your behalf. This credential is unrelated to Identity and Access Management (IAM) and Amazon Web Services credentials.

This parameter doesn’t set or change the authentication credentials on the XKS proxy. It just tells KMS the credential that you established on your external key store proxy. If you rotate your proxy authentication credential, use the UpdateCustomKeyStore operation to provide the new credential to KMS.

XksProxyConnectivity types.XksProxyConnectivityType

Indicates how KMS communicates with the external key store proxy. This parameter is required for custom key stores with a CustomKeyStoreType of EXTERNAL_KEY_STORE .

If the external key store proxy uses a public endpoint, specify PUBLIC_ENDPOINT . If the external key store proxy uses a Amazon VPC endpoint service for communication with KMS, specify VPC_ENDPOINT_SERVICE . For help making this choice, see a connectivity option[https://docs.aws.amazon.com/kms/latest/developerguide/plan-xks-keystore.html#choose-xks-connectivity]in the Key Management Service Developer Guide.

An Amazon VPC endpoint service keeps your communication with KMS in a private address space entirely within Amazon Web Services, but it requires more configuration, including establishing a Amazon VPC with multiple subnets, a VPC endpoint service, a network load balancer, and a verified private DNS name. A public endpoint is simpler to set up, but it might be slower and might not fulfill your security requirements. You might consider testing with a public endpoint, and then establishing a VPC endpoint service for production tasks. Note that this choice does not determine the location of the external key store proxy. Even if you choose a VPC endpoint service, the proxy can be hosted within the VPC or outside of Amazon Web Services such as in your corporate data center.

XksProxyUriEndpoint *string

Specifies the endpoint that KMS uses to send requests to the external key store proxy (XKS proxy). This parameter is required for custom key stores with a CustomKeyStoreType of EXTERNAL_KEY_STORE .

The protocol must be HTTPS. KMS communicates on port 443. Do not specify the port in the XksProxyUriEndpoint value.

For external key stores with XksProxyConnectivity value of VPC_ENDPOINT_SERVICE , specify https:// followed by the private DNS name of the VPC endpoint service.

For external key stores with PUBLIC_ENDPOINT connectivity, this endpoint must be reachable before you create the custom key store. KMS connects to the external key store proxy while creating the custom key store. For external key stores with VPC_ENDPOINT_SERVICE connectivity, KMS connects when you call the ConnectCustomKeyStore operation.

The value of this parameter must begin with https:// . The remainder can contain upper and lower case letters (A-Z and a-z), numbers (0-9), dots ( . ), and hyphens ( - ). Additional slashes ( / and \ ) are not permitted.

Uniqueness requirements:

  • The combined XksProxyUriEndpoint and XksProxyUriPath values must be unique in the Amazon Web Services account and Region.

  • An external key store with PUBLIC_ENDPOINT connectivity cannot use the same XksProxyUriEndpoint value as an external key store with VPC_ENDPOINT_SERVICE connectivity in this Amazon Web Services Region.

  • Each external key store with VPC_ENDPOINT_SERVICE connectivity must have its own private DNS name. The XksProxyUriEndpoint value for external key stores with VPC_ENDPOINT_SERVICE connectivity (private DNS name) must be unique in the Amazon Web Services account and Region.

XksProxyUriPath *string

Specifies the base path to the proxy APIs for this external key store. To find this value, see the documentation for your external key store proxy. This parameter is required for all custom key stores with a CustomKeyStoreType of EXTERNAL_KEY_STORE .

The value must start with / and must end with /kms/xks/v1 where v1 represents the version of the KMS external key store proxy API. This path can include an optional prefix between the required elements such as /prefix/kms/xks/v1 .

Uniqueness requirements:

  • The combined XksProxyUriEndpoint and XksProxyUriPath values must be unique in the Amazon Web Services account and Region.

XksProxyVpcEndpointServiceName *string

Specifies the name of the Amazon VPC endpoint service for interface endpoints that is used to communicate with your external key store proxy (XKS proxy). This parameter is required when the value of CustomKeyStoreType is EXTERNAL_KEY_STORE and the value of XksProxyConnectivity is VPC_ENDPOINT_SERVICE .

The Amazon VPC endpoint service must fulfill all requirements for use with an external key store.

Uniqueness requirements:

  • External key stores with VPC_ENDPOINT_SERVICE connectivity can share an Amazon VPC, but each external key store must have its own VPC endpoint service and private DNS name.

CreateCustomKeyStoreOutput struct

Structure Fields:

CustomKeyStoreId *string

A unique identifier for the new custom key store.

ResultMetadata middleware.Metadata

Metadata pertaining to the operation’s result.

CreateGrantInput struct

Structure Fields:

GranteePrincipal *string

The identity that gets the permissions specified in the grant.

To specify the grantee principal, use the Amazon Resource Name (ARN) of an Amazon Web Services principal. Valid principals include Amazon Web Services accounts, IAM users, IAM roles, federated users, and assumed role users. For help with the ARN syntax for a principal, see ARNs[https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_identifiers.html#identifiers-arns]in the Identity and Access Management User Guide .

This member is required.

KeyId *string

Identifies the KMS key for the grant. The grant gives principals permission to use this KMS key.

Specify the key ID or key ARN of the KMS key. To specify a KMS key in a different Amazon Web Services account, you must use the key 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

To get the key ID and key ARN for a KMS key, use ListKeys or DescribeKey.

This member is required.

Operations []types.GrantOperation

A list of operations that the grant permits.

This list must include only operations that are permitted in a grant. Also, the operation must be supported on the KMS key. For example, you cannot create a grant for a symmetric encryption KMS key that allows the Signoperation, or a grant for an asymmetric KMS key that allows the GenerateDataKeyoperation. If you try, KMS returns a ValidationError exception. For details, see Grant operations in the Key Management Service Developer Guide.

This member is required.

Constraints *types.GrantConstraints

Specifies a grant constraint.

Do not include confidential or sensitive information in this field. This field may be displayed in plaintext in CloudTrail logs and other output.

KMS supports the EncryptionContextEquals and EncryptionContextSubset grant constraints, which allow the permissions in the grant only when the encryption context in the request matches ( EncryptionContextEquals ) or includes ( EncryptionContextSubset ) the encryption context specified in the constraint.

The encryption context grant constraints are supported only on grant operations that include an EncryptionContext parameter, such as cryptographic operations on symmetric encryption KMS keys. Grants with grant constraints can include the DescribeKeyand RetireGrant operations, but the constraint doesn’t apply to these operations. If a grant with a grant constraint includes the CreateGrant operation, the constraint requires that any grants created with the CreateGrant permission have an equally strict or stricter encryption context constraint.

You cannot use an encryption context grant constraint for cryptographic operations with asymmetric KMS keys or HMAC KMS keys. Operations with these keys don’t support an encryption context.

Each constraint value can include up to 8 encryption context pairs. The encryption context value in each constraint cannot exceed 384 characters. For information about grant constraints, see grant constraints[https://docs.aws.amazon.com/kms/latest/developerguide/create-grant-overview.html#grant-constraints]in the Key Management Service Developer Guide. For more information about encryption context, see context[https://docs.aws.amazon.com/kms/latest/developerguide/concepts.html#encrypt_context]in the Key Management Service Developer Guide .

DryRun *bool

Checks if your request will succeed. DryRun is an optional parameter.

To learn more about how to use this parameter, see Testing your KMS API calls in the Key Management Service Developer Guide.

GrantTokens []string

A list of grant tokens.

Use a grant token when your permission to call this operation comes from a new grant that has not yet achieved eventual consistency. For more information, see Grant token and a grant token[https://docs.aws.amazon.com/kms/latest/developerguide/grant-manage.html#using-grant-token]in the Key Management Service Developer Guide.

Name *string

A friendly name for the grant. Use this value to prevent the unintended creation of duplicate grants when retrying this request.

Do not include confidential or sensitive information in this field. This field may be displayed in plaintext in CloudTrail logs and other output.

When this value is absent, all CreateGrant requests result in a new grant with a unique GrantId even if all the supplied parameters are identical. This can result in unintended duplicates when you retry the CreateGrant request.

When this value is present, you can retry a CreateGrant request with identical parameters; if the grant already exists, the original GrantId is returned without creating a new grant. Note that the returned grant token is unique with every CreateGrant request, even when a duplicate GrantId is returned. All grant tokens for the same grant ID can be used interchangeably.

RetiringPrincipal *string

The principal that has permission to use the RetireGrant operation to retire the grant.

To specify the principal, use the Amazon Resource Name (ARN) of an Amazon Web Services principal. Valid principals include Amazon Web Services accounts, IAM users, IAM roles, federated users, and assumed role users. For help with the ARN syntax for a principal, see ARNs[https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_identifiers.html#identifiers-arns]in the Identity and Access Management User Guide .

The grant determines the retiring principal. Other principals might have permission to retire the grant or revoke the grant. For details, see RevokeGrantand Retiring and revoking grants in the Key Management Service Developer Guide.

CreateGrantOutput struct

Structure Fields:

GrantId *string

The unique identifier for the grant.

You can use the GrantId in a ListGrants, RetireGrant, or RevokeGrant operation.

GrantToken *string

The grant token.

Use a grant token when your permission to call this operation comes from a new grant that has not yet achieved eventual consistency. For more information, see Grant token and a grant token[https://docs.aws.amazon.com/kms/latest/developerguide/grant-manage.html#using-grant-token]in the Key Management Service Developer Guide.

ResultMetadata middleware.Metadata

Metadata pertaining to the operation’s result.

CreateKeyInput struct

Structure Fields:

BypassPolicyLockoutSafetyCheck bool

Skips (“bypasses”) the key policy lockout safety check. The default value is false.

Setting this value to true increases the risk that the KMS key becomes unmanageable. Do not set this value to true indiscriminately.

For more information, see Default key policy in the Key Management Service Developer Guide.

Use this parameter only when you intend to prevent the principal that is making the request from making a subsequent PutKeyPolicy[https://docs.aws.amazon.com/kms/latest/APIReference/API_PutKeyPolicy.html]request on the KMS key.

CustomKeyStoreId *string

Creates the KMS key in the specified custom key store. The ConnectionState of the custom key store must be CONNECTED . To find the CustomKeyStoreID and ConnectionState use the DescribeCustomKeyStoresoperation.

This parameter is valid only for symmetric encryption KMS keys in a single Region. You cannot create any other type of KMS key in a custom key store.

When you create a KMS key in an CloudHSM key store, KMS generates a non-exportable 256-bit symmetric key in its associated CloudHSM cluster and associates it with the KMS key. When you create a KMS key in an external key store, you must use the XksKeyId parameter to specify an external key that serves as key material for the KMS key.

CustomerMasterKeySpec types.CustomerMasterKeySpec

Instead, use the KeySpec parameter.

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

Deprecated: This parameter has been deprecated. Instead, use the KeySpec parameter.

Description *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).

Do not include confidential or sensitive information in this field. This field may be displayed in plaintext in CloudTrail logs and other output.

To set or change the description after the key is created, use UpdateKeyDescription.

KeySpec types.KeySpec

Specifies the type of KMS key to create. The default value, SYMMETRIC_DEFAULT , creates a KMS key with a 256-bit AES-GCM key that is used for encryption and decryption, except in China Regions, where it creates a 128-bit symmetric key that uses SM4 encryption. For help choosing a key spec for your KMS key, see a KMS key type[https://docs.aws.amazon.com/kms/latest/developerguide/key-types.html#symm-asymm-choose]in the Key Management Service Developer Guide .

The KeySpec determines whether the KMS key contains a symmetric key or an asymmetric key pair. It also determines the algorithms that the KMS key supports. You can’t change the KeySpec after the KMS key is created. To further restrict the algorithms that can be used with the KMS key, use a condition key in its key policy or IAM policy. For more information, see kms:EncryptionAlgorithm, kms:MacAlgorithm or kms:Signing Algorithm in the Key Management Service Developer Guide .

Web Services services that are integrated with KMS[http://aws.amazon.com/kms/features/#AWS_Service_Integration]use symmetric encryption KMS keys to protect your data. These services do not support asymmetric KMS keys or HMAC KMS keys.

KMS supports the following key specs for KMS keys:

  • Symmetric encryption key (default)

  • SYMMETRIC_DEFAULT

  • HMAC keys (symmetric)

  • HMAC_224

  • HMAC_256

  • HMAC_384

  • HMAC_512

  • Asymmetric RSA key pairs (encryption and decryption -or- signing and verification)

  • RSA_2048

  • RSA_3072

  • RSA_4096

  • Asymmetric NIST-recommended elliptic curve key pairs (signing and verification -or- deriving shared secrets)

  • ECC_NIST_P256 (secp256r1)

  • ECC_NIST_P384 (secp384r1)

  • ECC_NIST_P521 (secp521r1)

  • Other asymmetric elliptic curve key pairs (signing and verification)

  • ECC_SECG_P256K1 (secp256k1), commonly used for cryptocurrencies.

  • SM2 key pairs (encryption and decryption -or- signing and verification -or- deriving shared secrets)

  • SM2 (China Regions only)

KeyUsage types.KeyUsageType

Determines the cryptographic operations for which you can use the KMS key. The default value is ENCRYPT_DECRYPT . This parameter is optional when you are creating a symmetric encryption KMS key; otherwise, it is required. You can’t change the KeyUsage value after the KMS key is created.

Select only one valid value.

  • For symmetric encryption KMS keys, omit the parameter or specify ENCRYPT_DECRYPT .

  • For HMAC KMS keys (symmetric), specify GENERATE_VERIFY_MAC .

  • For asymmetric KMS keys with RSA key pairs, specify ENCRYPT_DECRYPT or SIGN_VERIFY .

  • For asymmetric KMS keys with NIST-recommended elliptic curve key pairs, specify SIGN_VERIFY or KEY_AGREEMENT .

  • For asymmetric KMS keys with ECC_SECG_P256K1 key pairs specify SIGN_VERIFY .

  • For asymmetric KMS keys with SM2 key pairs (China Regions only), specify ENCRYPT_DECRYPT , SIGN_VERIFY , or KEY_AGREEMENT .

MultiRegion *bool

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 keys in KMS[https://docs.aws.amazon.com/kms/latest/developerguide/multi-region-keys-overview.html]in the Key Management Service Developer Guide.

This value creates a primary key, not a replica. To create a replica key, use the ReplicateKeyoperation.

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.

Origin types.OriginType

The source of the key material for the KMS key. You cannot change the origin after you create the KMS key. The default is AWS_KMS , which means that KMS creates the key material.

To create a KMS key with no key material (for imported key material), set this value to EXTERNAL . For more information about importing key material into KMS, see Key Material[https://docs.aws.amazon.com/kms/latest/developerguide/importing-keys.html]in the Key Management Service Developer Guide. The EXTERNAL origin value is valid only for symmetric KMS keys.

To create a KMS key in an CloudHSM key store and create its key material in the associated CloudHSM cluster, set this value to AWS_CLOUDHSM . You must also use the CustomKeyStoreId parameter to identify the CloudHSM key store. The KeySpec value must be SYMMETRIC_DEFAULT .

To create a KMS key in an external key store, set this value to EXTERNAL_KEY_STORE . You must also use the CustomKeyStoreId parameter to identify the external key store and the XksKeyId parameter to identify the associated external key. The KeySpec value must be SYMMETRIC_DEFAULT .

Policy *string

The key policy to attach to the KMS key.

If you provide a key policy, it must meet the following criteria:

  • The key policy must allow the calling principal to make a subsequent PutKeyPolicy request on the KMS key. This reduces the risk that the KMS key becomes unmanageable. For more information, see key policy[https://docs.aws.amazon.com/kms/latest/developerguide/key-policies.html#key-policy-default]in the Key Management Service Developer Guide. (To omit this condition, set BypassPolicyLockoutSafetyCheck to true.)

  • Each statement in the key policy must contain one or more principals. The principals in the key policy must exist and be visible to KMS. When you create a new Amazon Web Services principal, you might need to enforce a delay before including the new principal in a key policy because the new principal might not be immediately visible to KMS. For more information, see that I make are not always immediately visible[https://docs.aws.amazon.com/IAM/latest/UserGuide/troubleshoot_general.html#troubleshoot_general_eventual-consistency]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 key policy[https://docs.aws.amazon.com/kms/latest/developerguide/key-policies.html#key-policy-default]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 .

Tags []types.Tag

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 TagResourceoperation.

Do not include confidential or sensitive information in this field. This field may be displayed in plaintext in CloudTrail logs and other output.

Tagging or untagging a KMS key can allow or deny permission to the KMS key. For details, see for KMS[https://docs.aws.amazon.com/kms/latest/developerguide/abac.html]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.

XksKeyId *string

Identifies the external key that serves as key material for the KMS key in an external key store. Specify the ID that the key store proxy[https://docs.aws.amazon.com/kms/latest/developerguide/keystore-external.html#concept-xks-proxy]uses to refer to the external key. For help, see the documentation for your external key store proxy.

This parameter is required for a KMS key with an Origin value of EXTERNAL_KEY_STORE . It is not valid for KMS keys with any other Origin value.

The external key must be an existing 256-bit AES symmetric encryption key hosted outside of Amazon Web Services in an external key manager associated with the external key store specified by the CustomKeyStoreId parameter. This key must be enabled and configured to perform encryption and decryption. Each KMS key in an external key store must use a different external key. For details, see for a KMS key in an external key store[https://docs.aws.amazon.com/create-xks-keys.html#xks-key-requirements]in the Key Management Service Developer Guide.

Each KMS key in an external key store is associated two backing keys. One is key material that KMS generates. The other is the external key specified by this parameter. When you use the KMS key in an external key store to encrypt data, the encryption operation is performed first by KMS using the KMS key material, and then by the external key manager using the specified external key, a process known as double encryption. For details, see encryption[https://docs.aws.amazon.com/kms/latest/developerguide/keystore-external.html#concept-double-encryption]in the Key Management Service Developer Guide.

This member is required.

DryRun *bool

Checks if your request will succeed. DryRun is an optional parameter.

To learn more about how to use this parameter, see Testing your KMS API calls in the Key Management Service Developer Guide.

EncryptionAlgorithm types.EncryptionAlgorithmSpec

Specifies the encryption algorithm that will be used to decrypt the ciphertext. Specify the same algorithm that was used to encrypt the data. If you specify a different algorithm, the Decrypt operation fails.

This parameter is required only when the ciphertext was encrypted under an asymmetric KMS key. The default value, SYMMETRIC_DEFAULT , represents the only supported algorithm that is valid for symmetric encryption KMS keys.

EncryptionContext map[string]string

Specifies the encryption context to use when decrypting the data. An encryption context is valid only for operations[https://docs.aws.amazon.com/kms/latest/developerguide/concepts.html#cryptographic-operations]with a symmetric encryption KMS key. The standard asymmetric encryption algorithms and HMAC algorithms that KMS uses do not support an encryption context.

An encryption context is a collection of non-secret key-value pairs that represent additional authenticated data. When you use an encryption context to encrypt data, you must specify the same (an exact case-sensitive match) encryption context to decrypt the data. An encryption context is supported only on operations with symmetric encryption KMS keys. On operations with symmetric encryption KMS keys, an encryption context is optional, but it is strongly recommended.

For more information, see Encryption context in the Key Management Service Developer Guide.

GrantTokens []string

A list of grant tokens.

Use a grant token when your permission to call this operation comes from a new grant that has not yet achieved eventual consistency. For more information, see Grant token and a grant token[https://docs.aws.amazon.com/kms/latest/developerguide/grant-manage.html#using-grant-token]in the Key Management Service Developer Guide.

KeyId *string

Specifies the KMS key that KMS uses to decrypt the ciphertext.

Enter a key ID of the KMS key that was used to encrypt the ciphertext. If you identify a different KMS key, the Decrypt operation throws an IncorrectKeyException .

This parameter is required only when the ciphertext was encrypted under an asymmetric KMS key. If you used a symmetric encryption KMS key, KMS can get the KMS key from metadata that it adds to the symmetric ciphertext blob. However, it is always recommended as a best practice. This practice ensures that you use the KMS key that you intend.

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

Recipient *types.RecipientInfo

A signed attestation document from an Amazon Web Services Nitro enclave and the encryption algorithm to use with the enclave’s public key. The only valid encryption algorithm is RSAES_OAEP_SHA_256 .

This parameter only supports attestation documents for Amazon Web Services Nitro Enclaves. To call DeriveSharedSecret for an Amazon Web Services Nitro Enclaves, use the Web Services Nitro Enclaves SDK[https://docs.aws.amazon.com/enclaves/latest/user/developing-applications.html#sdk]to generate the attestation document and then use the Recipient parameter from any Amazon Web Services SDK to provide the attestation document for the enclave.

When you use this parameter, instead of returning a plaintext copy of the private data key, KMS encrypts the plaintext private data key under the public key in the attestation document, and returns the resulting ciphertext in the CiphertextForRecipient field in the response. This ciphertext can be decrypted only with the private key in the enclave. The CiphertextBlob field in the response contains a copy of the private data key encrypted under the KMS key specified by the KeyId parameter. The PrivateKeyPlaintext field in the response is null or empty.

A unique identifier for the KMS key that is used to reencrypt the data. Specify a symmetric encryption KMS key or an asymmetric KMS key with a KeyUsage value of ENCRYPT_DECRYPT . To find the KeyUsage value of a KMS key, use the DescribeKey operation.

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.

This member is required.

DestinationEncryptionAlgorithm types.EncryptionAlgorithmSpec

Specifies the encryption algorithm that KMS will use to reecrypt the data after it has decrypted it. The default value, SYMMETRIC_DEFAULT , represents the encryption algorithm used for symmetric encryption KMS keys.

This parameter is required only when the destination KMS key is an asymmetric KMS key.

DestinationEncryptionContext map[string]string

Specifies that encryption context to use when the reencrypting the data.

Do not include confidential or sensitive information in this field. This field may be displayed in plaintext in CloudTrail logs and other output.

A destination encryption context is valid only when the destination KMS key is a symmetric encryption KMS key. The standard ciphertext format for asymmetric KMS keys does not include fields for metadata.

An encryption context is a collection of non-secret key-value pairs that represent additional authenticated data. When you use an encryption context to encrypt data, you must specify the same (an exact case-sensitive match) encryption context to decrypt the data. An encryption context is supported only on operations with symmetric encryption KMS keys. On operations with symmetric encryption KMS keys, an encryption context is optional, but it is strongly recommended.

For more information, see Encryption context in the Key Management Service Developer Guide.

DryRun *bool

Checks if your request will succeed. DryRun is an optional parameter.

To learn more about how to use this parameter, see Testing your KMS API calls in the Key Management Service Developer Guide.

SourceEncryptionAlgorithm types.EncryptionAlgorithmSpec

Specifies the encryption algorithm that KMS will use to decrypt the ciphertext before it is reencrypted. The default value, SYMMETRIC_DEFAULT , represents the algorithm used for symmetric encryption KMS keys.

Specify the same algorithm that was used to encrypt the ciphertext. If you specify a different algorithm, the decrypt attempt fails.

This parameter is required only when the ciphertext was encrypted under an asymmetric KMS key.

SourceEncryptionContext map[string]string

Specifies the encryption context to use to decrypt the ciphertext. Enter the same encryption context that was used to encrypt the ciphertext.

An encryption context is a collection of non-secret key-value pairs that represent additional authenticated data. When you use an encryption context to encrypt data, you must specify the same (an exact case-sensitive match) encryption context to decrypt the data. An encryption context is supported only on operations with symmetric encryption KMS keys. On operations with symmetric encryption KMS keys, an encryption context is optional, but it is strongly recommended.

For more information, see Encryption context in the Key Management Service Developer Guide.

SourceKeyId *string

Specifies the KMS key that KMS will use to decrypt the ciphertext before it is re-encrypted.

Enter a key ID of the KMS key that was used to encrypt the ciphertext. If you identify a different KMS key, the ReEncrypt operation throws an IncorrectKeyException .

This parameter is required only when the ciphertext was encrypted under an asymmetric KMS key. If you used a symmetric encryption KMS key, KMS can get the KMS key from metadata that it adds to the symmetric ciphertext blob. However, it is always recommended as a best practice. This practice ensures that you use the KMS key that you intend.

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.

This member is required.

ReplicaRegion *string

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 service endpoints[https://docs.aws.amazon.com/general/latest/gr/kms.html#kms_region]in the Amazon Web Services General Reference.

HMAC KMS keys are not supported in all Amazon Web Services Regions. If you try to replicate an HMAC KMS key in an Amazon Web Services Region in which HMAC keys are not supported, the ReplicateKey operation returns an UnsupportedOperationException . For a list of Regions in which HMAC KMS keys are supported, see keys in KMS[https://docs.aws.amazon.com/kms/latest/developerguide/hmac.html]in the Key Management Service Developer Guide.

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 Resource Names (ARNs)[https://docs.aws.amazon.com/general/latest/gr/aws-arns-and-namespaces.html]in the Amazon Web Services General Reference. For information about enabling and disabling Regions, see a Region[https://docs.aws.amazon.com/general/latest/gr/rande-manage.html#rande-manage-enable]and Disabling a Region in the Amazon Web Services General Reference.

This member is required.

BypassPolicyLockoutSafetyCheck bool

Setting this value to true increases the risk that the KMS key becomes unmanageable. Do not set this value to true indiscriminately.

For more information, see Default key policy in the Key Management Service Developer Guide.

Use this parameter only when you intend to prevent the principal that is making the request from making a subsequent PutKeyPolicy[https://docs.aws.amazon.com/kms/latest/APIReference/API_PutKeyPolicy.html]request on the KMS key.

Description *string

A description of the KMS key. The default value is an empty string (no description).

Do not include confidential or sensitive information in this field. This field may be displayed in plaintext in CloudTrail logs and other output.

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.

Policy *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 key policy[https://docs.aws.amazon.com/kms/latest/developerguide/key-policies.html#key-policy-default]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:

  • The key policy must allow the calling principal to make a subsequent PutKeyPolicy request on the KMS key. This reduces the risk that the KMS key becomes unmanageable. For more information, see key policy[https://docs.aws.amazon.com/kms/latest/developerguide/key-policy-default.html#prevent-unmanageable-key]in the Key Management Service Developer Guide. (To omit this condition, set BypassPolicyLockoutSafetyCheck to true.)

  • Each statement in the key policy must contain one or more principals. The principals in the key policy must exist and be visible to KMS. When you create a new Amazon Web Services principal, you might need to enforce a delay before including the new principal in a key policy because the new principal might not be immediately visible to KMS. For more information, see that I make are not always immediately visible[https://docs.aws.amazon.com/IAM/latest/UserGuide/troubleshoot_general.html#troubleshoot_general_eventual-consistency]in the Amazon Web Services Identity and Access Management User Guide.

A key policy document can include only the following characters:

Tags []types.Tag

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 TagResourceoperation.

Do not include confidential or sensitive information in this field. This field may be displayed in plaintext in CloudTrail logs and other output.

Tagging or untagging a KMS key can allow or deny permission to the KMS key. For details, see for KMS[https://docs.aws.amazon.com/kms/latest/developerguide/abac.html]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.

Use a grant token when your permission to call this operation comes from a new grant that has not yet achieved eventual consistency. For more information, see Grant token and a grant token[https://docs.aws.amazon.com/kms/latest/developerguide/grant-manage.html#using-grant-token]in the Key Management Service Developer Guide.

MessageType types.MessageType

Tells KMS whether the value of the Message parameter should be hashed as part of the signing algorithm. Use RAW for unhashed messages; use DIGEST for message digests, which are already hashed.

When the value of MessageType is RAW , KMS uses the standard signing algorithm, which begins with a hash function. When the value is DIGEST , KMS skips the hashing step in the signing algorithm.

Use the DIGEST value only when the value of the Message parameter is a message digest. If you use the DIGEST value with an unhashed message, the security of the signing operation can be compromised.

When the value of MessageType is DIGEST , the length of the Message value must match the length of hashed messages for the specified signing algorithm.

You can submit a message digest and omit the MessageType or specify RAW so the digest is hashed again while signing. However, this can cause verification failures when verifying with a system that assumes a single hash.

The hashing algorithm in that Sign uses is based on the SigningAlgorithm value.

  • Signing algorithms that end in SHA_256 use the SHA_256 hashing algorithm.

  • Signing algorithms that end in SHA_384 use the SHA_384 hashing algorithm.

  • Signing algorithms that end in SHA_512 use the SHA_512 hashing algorithm.

  • SM2DSA uses the SM3 hashing algorithm. For details, see Offline verification with SM2 key pairs.

SignOutput struct

Structure Fields:

KeyId *string
