Hi, I think such an update should also include guidance on tag truncation (i.e. do not truncate), perhaps in the security consideration section. This was raised by Jim Schaad on the CFRG list. https://www.ietf.org/mail-archive/web/cfrg/current/msg07176.html I have also heard discussions on truncating poly1305 in other places. If there any other clarifications regarding secure or interoperable implementations, I think they should be added as well.

There have been 7 errata filed against it. Most of it is editorial or insignificant, but still no errata is better than some errata. So what do the participants and chairs think about spinning up a quick[4] rfc7539bis that has the same text, except that the errata will be merged in? This chair thinks it is a good idea. I think such a document should be fairly easy and quick. Yoav P.S: and yes, of course I’m volunteering to write it.

The contents of my mails are veering far away from regular English. _______________________________________________ Cfrg mailing list Cfrg@irtf.org<mailto:Cfrg@irtf.org> https://www.irtf.org/mailman/listinfo/cfrg
