NAME

Paws::KMS::CreateGrant - Arguments for method CreateGrant on Paws::KMS

DESCRIPTION

This class represents the parameters used for calling the method CreateGrant on the AWS Key Management Service service. Use the attributes of this class as arguments to method CreateGrant.

You shouldn't make instances of this class. Each attribute should be used as a named argument in the call to CreateGrant.

SYNOPSIS

 my $kms = Paws->service('KMS');
# To create a grant
# The following example creates a grant that allows the specified IAM role to
# encrypt data with the specified customer master key (CMK).
 my $CreateGrantResponse = $kms->CreateGrant(
   'GranteePrincipal' => 'arn:aws:iam::111122223333:role/ExampleRole',
   'KeyId'            =>
'arn:aws:kms:us-east-2:444455556666:key/1234abcd-12ab-34cd-56ef-1234567890ab',
   'Operations' => [ 'Encrypt', 'Decrypt' ]
 );

 # Results:
 my $GrantId    = $CreateGrantResponse->GrantId;
 my $GrantToken = $CreateGrantResponse->GrantToken;

 # Returns a L<Paws::KMS::CreateGrantResponse> object.

Values for attributes that are native types (Int, String, Float, etc) can passed as-is (scalar values). Values for complex Types (objects) can be passed as a HashRef. The keys and values of the hashref will be used to instance the underlying object. For the AWS API documentation, see https://docs.aws.amazon.com/goto/WebAPI/kms/CreateGrant

ATTRIBUTES

Constraints => Paws::KMS::GrantConstraints

Specifies a grant constraint.

AWS 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 a cryptographic operation (https://docs.aws.amazon.com/kms/latest/developerguide/concepts.html#cryptographic-operations) only when the encryption context in the request matches (EncryptionContextEquals) or includes (EncryptionContextSubset) the encryption context specified in this structure. For more information about encryption context, see Encryption Context (https://docs.aws.amazon.com/kms/latest/developerguide/concepts.html#encrypt_context) in the AWS Key Management Service Developer Guide . For information about grant constraints, see Using grant constraints (https://docs.aws.amazon.com/kms/latest/developerguide/create-grant-overview.html#grant-constraints) in the AWS Key Management Service Developer Guide.

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 CMKs or for management operations, such as DescribeKey or RetireGrant.

REQUIRED GranteePrincipal => Str

The identity that gets the permissions specified in the grant.

To specify the principal, use the Amazon Resource Name (ARN) (https://docs.aws.amazon.com/general/latest/gr/aws-arns-and-namespaces.html) of an AWS principal. Valid AWS principals include AWS 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 AWS Identity and Access Management (IAM) (https://docs.aws.amazon.com/general/latest/gr/aws-arns-and-namespaces.html#arn-syntax-iam) in the Example ARNs section of the AWS General Reference.

GrantTokens => ArrayRef[Str|Undef]

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 (https://docs.aws.amazon.com/kms/latest/developerguide/concepts.html#grant_token) in the AWS Key Management Service Developer Guide.

REQUIRED KeyId => Str

Identifies the customer master key (CMK) for the grant. The grant gives principals permission to use this CMK.

Specify the key ID or key ARN of the CMK. To specify a CMK in a different AWS 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 CMK, use ListKeys or DescribeKey.

Name => Str

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.

REQUIRED Operations => ArrayRef[Str|Undef]

A list of operations that the grant permits.

The operation must be supported on the CMK. For example, you cannot create a grant for a symmetric CMK that allows the Sign operation, or a grant for an asymmetric CMK that allows the GenerateDataKey operation. If you try, AWS KMS returns a ValidationError exception. For details, see Grant operations (https://docs.aws.amazon.com/kms/latest/developerguide/grants.html#terms-grant-operations) in the AWS Key Management Service Developer Guide.

RetiringPrincipal => Str

The principal that is given permission to retire the grant by using RetireGrant operation.

To specify the principal, use the Amazon Resource Name (ARN) (https://docs.aws.amazon.com/general/latest/gr/aws-arns-and-namespaces.html) of an AWS principal. Valid AWS principals include AWS accounts (root), IAM users, federated users, and assumed role users. For examples of the ARN syntax to use for specifying a principal, see AWS Identity and Access Management (IAM) (https://docs.aws.amazon.com/general/latest/gr/aws-arns-and-namespaces.html#arn-syntax-iam) in the Example ARNs section of the AWS General Reference.
