-- This method takes a user pool ID, and returns the signing certificate.
-- The issued certificate is valid for 10 years from the date of issue.
--
-- Amazon Cognito issues and assigns a new signing certificate annually.
-- This process returns a new value in the response to
-- @GetSigningCertificate@, but doesn\'t invalidate the original
-- certificate.
