-- Retires a grant. You can retire a grant when you\'re done using it to
-- clean up. You should revoke a grant when you intend to actively deny
-- operations that depend on it. The following are permitted to call this
-- API:
--
-- -   The account that created the grant
-- -   The 'RetiringPrincipal', if present
-- -   The 'GranteePrincipal', if 'RetireGrant' is a grantee operation
--
-- The grant to retire must be identified by its grant token or by a
-- combination of the key ARN and the grant ID. A grant token is a unique
-- variable-length base64-encoded string. A grant ID is a 64 character
-- unique identifier of a grant. Both are returned by the 'CreateGrant'
-- function.

-- /See:/ <http://docs.aws.amazon.com/kms/latest/APIReference/API_RetireGrant.html AWS API Reference> for RetireGrant.
