RFC 的详细文档！

   It is explicitly allowed for an agent to decrypt a combined message
   and rewrite it as a multipart/signed object using the signature data
   embedded in the encrypted version.

7.  Distribution of OpenPGP public keys

   Content-Type: application/pgp-keys
   Required parameters: none
   Optional parameters: none

   A MIME body part of the content type "application/pgp-keys" contains
   ASCII-armored transferable Public Key Packets as defined in [1],
   section 10.1.

8.  Security Considerations

   Signatures of a canonical text document as defined in [1] ignore
   trailing white space in signed material.  Implementations which
   choose to use signatures of canonical text documents will not be able
   to detect the addition of whitespace in transit.

   See [3], [4] for more information on the security considerations
   concerning the underlying protocols.

9.  IANA Considerations

   This document defines three media types: "application/pgp-encrypted",
   "application/pgp-signature" and "application/pgp-keys".  The
   following sections specify the IANA registrations for these types.

9.1.  Registration of the application/pgp-encrypted media type

   MIME media type name: application
   MIME subtype name: pgp-encrypted
   Required parameters: none
   Optional parameters: none

   Encoding considerations:

      Currently this media type always consists of a single 7bit text
      string.

   Security considerations:

      See Section 8 and RFC 2440 Section 13.

   Interoperability considerations: none

   Published specification:

      This document.

   Additional information:

      Magic number(s): none
      File extension(s): none
      Macintosh File Type Code(s): none

   Person & email address to contact for further information:

9.2.  Registration of the application/pgp-signature media type

   MIME media type name: application
   MIME subtype name: pgp-signature
   Required parameters: none
   Optional parameters: none

   Encoding considerations:

      The content of this media type always consists of 7bit text.

   Security considerations:

      See Section 8 and RFC 2440 Section 13.

   Interoperability considerations: none

   Published specification:

      RFC 2440 and this document.

   Additional information:

      Magic number(s): none
      File extension(s): asc, sig
      Macintosh File Type Code(s): pgDS

   Person & email address to contact for further information:

9.3.  Registration of the application/pgp-keys media type

   MIME media type name: application
   MIME subtype name: pgp-keys
   Required parameters: none
   Optional parameters: none

11.  Acknowledgements

   This document relies on the work of the IETF's OpenPGP Working
   Group's definitions of the OpenPGP Message Format.  The OpenPGP
   message format is currently described in RFC 2440 [1].

   Special thanks are due: to Philip Zimmermann for his original and
   ongoing work on PGP; to Charles Breed, Jon Callas and Dave Del Torto
   for originally proposing the formation of the OpenPGP Working Group;
   and to Steve Schoenfeld for helpful feedback during the draft
   process.  The authors would also like to thank the engineers at
   Pretty Good Privacy, Inc (now Network Associates, Inc), including
   Colin Plumb, Hal Finney, Jon Callas, Mark Elrod, Mark Weaver and
   Lloyd Chambers, for their technical commentary.

   Additional thanks are due to Jeff Schiller and Derek Atkins for their
   continuing support of strong cryptography and PGP freeware at MIT; to
   Rodney Thayer of Sable Technology; to John Noerenberg, Steve Dorner
   and Laurence Lundblade of the Eudora team at QUALCOMM, Inc; to Bodo
   Moeller for proposing the approach followed with respect to trailing
   whitespace; to John Gilmore, Hugh Daniel and Fred Ringel (at
   Rivertown) and Ian Bell (at Turnpike) for their timely critical
   commentary; and to the international members of the IETF's OpenPGP
   mailing list, including William Geiger, Lutz Donnerhacke and Kazu
   Yamamoto.  The idea to use multipart/mixed with multipart/signed has
   been attributed to James Galvin.  Finally, our gratitude is due to
   the many members of the "Cypherpunks," "Coderpunks" and "pgp-users"
   <http://cryptorights.org/pgp-users> mailing lists and the many users
   of PGP worldwide for helping keep the path to privacy open.
