Following up on Werner’s comment on OCB and Phil Rogaway:

The Rogaway patent (US8321675B2) expired a year ago. The Jutla/IBM
patent (US6963976B1), which may be related to OCB, will also expire this
November. Let's ask Rogaway; actually this has been on the todo list of
the WG for years (to get a general grant like he did for OpenSSL).

Phil has previously made this statement on OCB in the CFRG list:
https://mailarchive.ietf.org/arch/msg/cfrg/qLTveWOdTJcLn4HP3ev-vrj05Vg/

To which Werner replied to here :)
https://mailarchive.ietf.org/arch/msg/openpgp/jOHNaaUHs__z7icddEWeNsQCLuQ/

I can confirm that I have abandoned all OCB patents
and placed into the public domain all OCB-related IP of mine.
While I have been telling people this for quite some time, I don't
think I ever made a proper announcement to the CFRG or on the
OCB webpage. Consider that done.

I hope people will use the scheme to do positive things.

phil

Prior to that statement, Phil provided RNP with an explicit OCB license grant (https://github.com/rnpgp/rnp/blob/master/LICENSE-OCB.md). He was supportive of OCB being used in OpenPGP for free, and therefore made the CFRG announcement. GnuPG’s OCB implementation was also covered by Phil’s grant (compatibility testing was done between RNP and GnuPG).

Kind regards,
Ron
