Method Detail

keyId

public final String keyId()

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.

Returns:

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.

granteePrincipal

public final String granteePrincipal()

The identity that gets the permissions specified in the grant.

To specify the principal, use the Amazon Resource Name (ARN) 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) in the Example ARNs section of the Amazon Web Services General Reference.

Returns:

The identity that gets the permissions specified in the grant.

To specify the principal, use the Amazon Resource Name (ARN) 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) in the Example ARNs section of the Amazon Web Services General Reference.

retiringPrincipal

public final String retiringPrincipal()

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 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) 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 in the Key Management Service Developer Guide.

Returns:

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 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) 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 in the Key Management Service Developer Guide.

operations

public final List<GrantOperation> operations()

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.

Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasOperations() method.

Returns:

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.

hasOperations

public final boolean hasOperations()

For responses, this returns true if the service returned a value for the Operations property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

operationsAsStrings

public final List<String> operationsAsStrings()

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.

If you try, KMS returns a ValidationError exception. For details, see Grant operations in the Key Management Service Developer Guide.

constraints

public final GrantConstraints 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. For information about grant constraints, see Using grant constraints in the Key Management Service Developer Guide. For more information about encryption context, see Encryption context in the Key Management Service Developer Guide .

The 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 this structure.

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 DescribeKey and 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. These keys don't support an encryption context.

Returns:

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

hasGrantTokens

public final boolean hasGrantTokens()

For responses, this returns true if the service returned a value for the GrantTokens property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

grantTokens

public final List<String> grantTokens()

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.

Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasGrantTokens() method.

Returns:

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.

name

public final String 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.

Returns:

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