class Aws::KMS::Types::CreateGrantRequest
@note When making an API call, you may pass CreateGrantRequest
data as a hash: { key_id: "KeyIdType", # required grantee_principal: "PrincipalIdType", # required retiring_principal: "PrincipalIdType", operations: ["Decrypt"], # required, accepts Decrypt, Encrypt, GenerateDataKey, GenerateDataKeyWithoutPlaintext, ReEncryptFrom, ReEncryptTo, Sign, Verify, GetPublicKey, CreateGrant, RetireGrant, DescribeKey, GenerateDataKeyPair, GenerateDataKeyPairWithoutPlaintext constraints: { encryption_context_subset: { "EncryptionContextKey" => "EncryptionContextValue", }, encryption_context_equals: { "EncryptionContextKey" => "EncryptionContextValue", }, }, grant_tokens: ["GrantTokenType"], name: "GrantNameType", }
@!attribute [rw] key_id
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. @return [String]
@!attribute [rw] grantee_principal
The identity that gets the permissions specified in the grant. To specify the principal, use the [Amazon Resource Name (ARN)][1] of an Amazon Web Services principal. Valid Amazon Web Services principals include Amazon Web Services accounts (root), IAM users, IAM roles, federated users, and assumed role users. For examples of the ARN syntax to use for specifying a principal, see [Amazon Web Services Identity and Access Management (IAM)][2] in the Example ARNs section of the *Amazon Web Services General Reference*. [1]: https://docs.aws.amazon.com/general/latest/gr/aws-arns-and-namespaces.html [2]: https://docs.aws.amazon.com/general/latest/gr/aws-arns-and-namespaces.html#arn-syntax-iam @return [String]
@!attribute [rw] retiring_principal
The principal that has permission to use the RetireGrant operation to retire the grant. To specify the principal, use the [Amazon Resource Name (ARN)][1] of an Amazon Web Services principal. Valid Amazon Web Services principals include Amazon Web Services accounts (root), IAM users, federated users, and assumed role users. For examples of the ARN syntax to use for specifying a principal, see [Amazon Web Services Identity and Access Management (IAM)][2] in the Example ARNs section of the *Amazon Web Services General Reference*. The grant determines the retiring principal. Other principals might have permission to retire the grant or revoke the grant. For details, see RevokeGrant and [Retiring and revoking grants][3] in the *Key Management Service Developer Guide*. [1]: https://docs.aws.amazon.com/general/latest/gr/aws-arns-and-namespaces.html [2]: https://docs.aws.amazon.com/general/latest/gr/aws-arns-and-namespaces.html#arn-syntax-iam [3]: https://docs.aws.amazon.com/kms/latest/developerguide/grant-manage.html#grant-delete @return [String]
@!attribute [rw] operations
A list of operations that the grant permits. The operation must be supported on the KMS key. For example, you cannot create a grant for a symmetric KMS key that allows the Sign operation, or a grant for an asymmetric KMS key that allows the GenerateDataKey operation. If you try, KMS returns a `ValidationError` exception. For details, see [Grant operations][1] in the *Key Management Service Developer Guide*. [1]: https://docs.aws.amazon.com/kms/latest/developerguide/grants.html#terms-grant-operations @return [Array<String>]
@!attribute [rw] constraints
Specifies a grant constraint. KMS supports the `EncryptionContextEquals` and `EncryptionContextSubset` grant constraints. Each constraint value can include up to 8 encryption context pairs. The encryption context value in each constraint cannot exceed 384 characters. These grant constraints allow the permissions in the grant only when the encryption context in the request matches (`EncryptionContextEquals`) or includes (`EncryptionContextSubset`) the encryption context specified in this structure. For information about grant constraints, see [Using grant constraints][1] in the *Key Management Service Developer Guide*. For more information about encryption context, see [Encryption Context][2] in the <i> <i>Key Management Service Developer Guide</i> </i>. The encryption context grant constraints are supported only on operations that include an encryption context. You cannot use an encryption context grant constraint for cryptographic operations with asymmetric KMS keys or for management operations, such as DescribeKey or RetireGrant.

@!attribute [rw] grant_tokens
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][1] and [Using a grant token][2] in the *Key Management Service Developer Guide*. [1]: https://docs.aws.amazon.com/kms/latest/developerguide/grants.html#grant_token [2]: https://docs.aws.amazon.com/kms/latest/developerguide/grant-manage.html#using-grant-token @return [Array<String>]
@!attribute [rw] name
A friendly name for the grant. Use this value to prevent the unintended creation of duplicate grants when retrying this request. 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. @return [String]
