=head1 NAME

Paws::Firehose::DeliveryStreamEncryptionConfigurationInput

=head1 USAGE

This class represents one of two things:

=head3 Arguments in a call to a service

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::Firehose::DeliveryStreamEncryptionConfigurationInput object:

  $service_obj->Method(Att1 => { KeyARN => $value, ..., KeyType => $value  });

=head3 Results returned from an API call

Use accessors for each attribute. If Att1 is expected to be an Paws::Firehose::DeliveryStreamEncryptionConfigurationInput object:

  $result = $service_obj->Method(...);
  $result->Att1->KeyARN

=head1 DESCRIPTION

Specifies the type and Amazon Resource Name (ARN) of the CMK to use for
Server-Side Encryption (SSE).

=head1 ATTRIBUTES


=head2 KeyARN => Str

If you set C<KeyType> to C<CUSTOMER_MANAGED_CMK>, you must specify the
Amazon Resource Name (ARN) of the CMK. If you set C<KeyType> to
C<AWS_OWNED_CMK>, Kinesis Data Firehose uses a service-account CMK.


=head2 B<REQUIRED> KeyType => Str

Indicates the type of customer master key (CMK) to use for encryption.
The default setting is C<AWS_OWNED_CMK>. For more information about
CMKs, see Customer Master Keys (CMKs)
(https://docs.aws.amazon.com/kms/latest/developerguide/concepts.html#master_keys).
When you invoke CreateDeliveryStream or StartDeliveryStreamEncryption
with C<KeyType> set to CUSTOMER_MANAGED_CMK, Kinesis Data Firehose
invokes the Amazon KMS operation CreateGrant
(https://docs.aws.amazon.com/kms/latest/APIReference/API_CreateGrant.html)
to create a grant that allows the Kinesis Data Firehose service to use
the customer managed CMK to perform encryption and decryption. Kinesis
Data Firehose manages that grant.

When you invoke StartDeliveryStreamEncryption to change the CMK for a
delivery stream that is encrypted with a customer managed CMK, Kinesis
Data Firehose schedules the grant it had on the old CMK for retirement.

You can use a CMK of type CUSTOMER_MANAGED_CMK to encrypt up to 500
delivery streams. If a CreateDeliveryStream or
StartDeliveryStreamEncryption operation exceeds this limit, Kinesis
Data Firehose throws a C<LimitExceededException>.

To encrypt your delivery stream, use symmetric CMKs. Kinesis Data
Firehose doesn't support asymmetric CMKs. For information about
symmetric and asymmetric CMKs, see About Symmetric and Asymmetric CMKs
(https://docs.aws.amazon.com/kms/latest/developerguide/symm-asymm-concepts.html)
in the AWS Key Management Service developer guide.
