         Textual Specification for Certificates and Attributes
                       draft-seantek-certspec-11

Abstract

   Digital certificates are used in many systems and protocols to
   identify and authenticate parties.  This document describes a string
   format that identifies certificates, along with optional attributes.
   This string format has been engineered to work without re-encoding in
   a variety of protocol slots.
