Paws::KMS::GrantConstraints
This class represents one of two things:
Use the attributes of this class as arguments to methods. You shouldn't make instances of this class. Each attribute should be used as a named argument in the calls that expect this type of object.
As an example, if Att1 is expected to be a Paws::KMS::GrantConstraints object:
$service_obj->Method(Att1 => { EncryptionContextEquals => $value, ..., EncryptionContextSubset => $value });
Use accessors for each attribute. If Att1 is expected to be an Paws::KMS::GrantConstraints object:
$result = $service_obj->Method(...); $result->Att1->EncryptionContextEquals
Use this structure to allow cryptographic operations in the grant only when the operation request includes the specified encryption context (https://docs.aws.amazon.com/kms/latest/developerguide/concepts.html#encrypt_context).
AWS KMS applies the grant constraints only when the grant allows a cryptographic operation that accepts an encryption context as input, such as the following.
Encrypt
Decrypt
GenerateDataKey
GenerateDataKeyWithoutPlaintext
ReEncrypt
AWS KMS does not apply the grant constraints to other operations, such as DescribeKey or ScheduleKeyDeletion.
In a cryptographic operation, the encryption context in the decryption operation must be an exact, case-sensitive match for the keys and values in the encryption context of the encryption operation. Only the order of the pairs can vary.
However, in a grant constraint, the key in each key-value pair is not case sensitive, but the value is case sensitive.
To avoid confusion, do not use multiple encryption context pairs that differ only by case. To require a fully case-sensitive encryption context, use the kms:EncryptionContext: and kms:EncryptionContextKeys conditions in an IAM or key policy. For details, see kms:EncryptionContext: (https://docs.aws.amazon.com/kms/latest/developerguide/policy-conditions.html#conditions-kms-encryption-context) in the AWS Key Management Service Developer Guide .
kms:EncryptionContext:
kms:EncryptionContextKeys
A list of key-value pairs that must match the encryption context in the cryptographic operation request. The grant allows the operation only when the encryption context in the request is the same as the encryption context specified in this constraint.
A list of key-value pairs that must be included in the encryption context of the cryptographic operation request. The grant allows the cryptographic operation only when the encryption context in the request includes the key-value pairs specified in this constraint, although it can include additional key-value pairs.
