Thank you Werner for pushing the draft forward!

Given the latest status of the openpgp wg, perhaps the wg chairs could briefly clarify what needs to be done for draft adoption?

Personally I am highly supportive of this draft, and believe some others are too.

Ron

Hi!

I just pushed -03 with these changes

  o  Changed v5 key fingerprint format to full 32 octets.

  o  Added Literal Data Packet format octet 'm'.

  o  Added Feature Flag for v5 key support.
     [Not yet discussed in the WG]

  o  Added AEAD Encrypted Data Packet.
     [I also added a feature flag and a Preferred AEAD Algorithms
     signature subpacket]

  o  Removed notes on extending the MDC packet.
     [Not yet discussed in the WG]


I also noted

  o  The OCB mode is patented and a debate is still underway on whether
     it can be included in RFC4880bis or needs to be moved to a
     separate document.  For the sole purpose of experimenting with the
     Preferred AEAD Algorithms signature subpacket it is has been
     included in this I-D.



Shalom-Salam,

  Werner
