def constraints : GrantConstraints | Nil #

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 following grant constraints.

  • EncryptionContextEquals and EncryptionContextSubset — These encryption context 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 the constraint.

Encryption context grant constraints are supported only on grant operations that include an EncryptionContext parameter, such as cryptographic operations on symmetric encryption KMS keys. 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. Grants with encryption context grant constraints can include the DescribeKey and RetireGrant operations, but the constraint doesn't apply to these operations. If a grant with an encryption context 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.

Each constraint value can include up to 8 encryption context pairs. The encryption context value in each constraint cannot exceed 384 characters. For more information about encryption context, see Encryption context in the * Key Management Service Developer Guide *.

  • SourceArn — This grant constraint allows the permissions in the grant only when the request is made on behalf of a specific Amazon Web Services resource, identified by its Amazon Resource Name (ARN). This is effectively the same as having the aws:SourceArn global condition key in the grant. The SourceArn constraint is supported on grants for all types of KMS keys and can also be applied to the DescribeKey operation when specified in the request. However, it does not apply to RetireGrant operation.

For information about grant constraints, see Using grant constraints in the Key Management Service Developer Guide.

def grant_tokens : Array(String) | Nil #

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 Using a grant token in the Key Management Service Developer Guide.

def grant_tokens=(grant_tokens : Array(String) | Nil) #

def grantee_principal : String | Nil #

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 IAM ARNs in the * Identity and Access Management User Guide *.

You must specify either GranteePrincipal or GranteeServicePrincipal, but not both.

def grantee_service_principal : String | Nil #

The Amazon Web Services service principal that gets the permissions specified in the grant.

When you specify a GranteeServicePrincipal, you must also specify a SourceArn grant constraint. In addition, you must specify either a RetiringPrincipal or a RetiringServicePrincipal.

You must specify either GranteePrincipal or GranteeServicePrincipal, but not both.

def key_id : 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.

def key_id=(key_id : 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

def name : String | Nil #

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.

def operations : Array(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 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 in the Key Management Service Developer Guide.

def retiring_principal : String | Nil #

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 IAM 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 RevokeGrant and Retiring and revoking grants in the Key Management Service Developer Guide.

You can specify either RetiringPrincipal or RetiringServicePrincipal, but not both.
