Use of Short-Term, Automatically-Renewed (STAR) Certificates to Delegate
                        Authority over Web Sites
                        draft-ietf-acme-star-00

Abstract

   This memo proposes an ACME extension to enable the issuance of short-
   term and automatically renewed certificates.  This allows a domain
   name owner to delegate the use of certificates to another party,
   while retaining the capability to cancel this delegation at any time
   with no need to rely on certificate revocation mechanisms.
