Abstract

   This document updates RFC7030: Enrollment over Secure Transport (EST)
   to resolve some errata that were reported, and which have proven to
   cause interoperability issues when RFC7030 was extended.

   This document deprecates the specification of "Content-Transfer-
   Encoding" headers for EST endpoints.  This document fixes some
   syntactical errors in ASN.1 that were present.

1.  Introduction

   Enrollment over Secure Transport (EST) is defined in [RFC7030].  The
   EST specification defines a number of HTTP end points for certificate
   enrollment and management.  The details of the transaction were
   defined in terms of MIME headers as defined in [RFC2045], rather than
   in terms of the HTTP protocol as defined in [RFC7230] and [RFC7231].

   [RFC2616] and later [RFC7231] Appendix A.5 has text specifically
   deprecating Content-Transfer-Encoding.  However, [RFC7030]
