Abstract

   This document defines a set of ways to identify a thing using the
   output from a hash function, specifying URI, URL, binary and human
   "speakable" formats for these names.  The various formats are
   designed to support, but not require, a strong link to the referenced
   object such that the referenced object may be authenticated to the
   same degree as the reference to it.

1.  Introduction

   Names or identifiers are used in various protocols for identifying
   resources.  In many scenarios those names or identifiers contain
   values that are hash function outputs.  However, different
   deployments have chosen various different ways to include hash
   function outputs in such names or identifiers.  There is a benefit in
   specifying a standard way to include hash function outputs in such
   names or identifiers so we do that here.

   Hash function outputs can be used to ensure uniqueness in terms of
   mapping URIs [RFC3986] to a specific resource, or to make URIs hard
