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.
