Instance Attribute Details

#dry_run ⇒ Boolean

Checks if your request will succeed. ‘DryRun` is an optional parameter.

To learn more about how to use this parameter, see [Testing your permissions] in the *Key Management Service Developer Guide*.

  :key_id,

  :grant_tokens,
  :dry_run)
  SENSITIVE = [:message]
  include Aws::Structure
end

#grant_tokens ⇒ Array<String>

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*.

class GenerateMacRequest < Struct.new(
  :message,
  :key_id,
  :mac_algorithm,
  :grant_tokens,
  :dry_run)
  SENSITIVE = [:message]
  include Aws::Structure
end

#key_id ⇒ String

The HMAC KMS key to use in the operation. The MAC algorithm computes the HMAC for the message and the key as described in [RFC 2104].

To identify an HMAC KMS key, use the DescribeKey operation and see the ‘KeySpec` field in the response.

class GenerateMacRequest < Struct.new(
  :message,
  :key_id,
  :mac_algorithm,
  :grant_tokens,
  :dry_run)
  SENSITIVE = [:message]
  include Aws::Structure
end

#mac_algorithm ⇒ String

The MAC algorithm used in the operation.

The algorithm must be compatible with the HMAC KMS key that you specify. To find the MAC algorithms that your HMAC KMS key supports, use the DescribeKey operation and see the ‘MacAlgorithms` field in the `DescribeKey` response.

# File 'lib/aws-sdk-kms/types.rb', line 3232

class GenerateMacRequest < Struct.new(
  :message,
  :key_id,
  :mac_algorithm,
  :grant_tokens,
  :dry_run)
  SENSITIVE = [:message]
  include Aws::Structure
end

#message ⇒ String

The message to be hashed. Specify a message of up to 4,096 bytes.

‘GenerateMac` and VerifyMac do not provide special handling for message digests. If you generate an HMAC for a hash digest of a message, you must verify the HMAC of the same hash digest.

class GenerateMacRequest < Struct.new(
  :message,
  :key_id,
  :mac_algorithm,
