[auth48] Re: AUTH48: RFC-to-be 9966 <draft-ietf-emu-bootstrapped-tls-11> for your review

["Harkins, Dan" <[e-mail]>]

  Hi Megan,

  Question 5 was about adding a space between C and 9 to make it "target_kdf = <as per RFC 9258>". That seems to have been done correctly. You say you don't know how to update for #6 but that looks correct, the line has become +s in Figure 1. Can you please clarify what the question is?

  I apologize for the formatting of this reply but HPE uses Outlook and for the life of me I can't get it to format a reply correctly. So for the test vector issues please see replies with [DNH] below. Please let us know whether those breaks in the test vectors work.

  Regards,

  Dan.

Hi Dan and Owen,


Thank you for your replies and guidance. 


We have updated as requested and have only the following outstanding issues to resolve:


Regarding SVG updates (Question 5 and 6): 
We believe we were able to correctly update the SVG to resolve our Question # 5, but are not sure how to update for #6. It is certainly an option to just use the ASCII version. Otherwise, you can change the SVG to use the pluses and either update the edited XML file (linked below) to include your new SVG and email it to us or just email us the SVG and we can pop it in.


Regarding the test vectors:
We have updated to use <sourcecode type=“test-vectors”> but will still need some author guidance as to how to break the lines to fit within the character limit. Warnings below:


Warning: Too long line found (L643), 11 characters longer than 72 characters: 
MDkwEwYHKoZIzj0CAQYIKoZIzj0DAQcDIgACMvLyoOykj8sFJxSoZfzafuVEvM+kNYCxpEC6KITLb9g=

[DNH] it should be broken at "Cxp" so it should be:
MDkwEwYHKoZIzj0CAQYIKoZIzj0DAQcDIgACMvLyoOykj8sFJxSoZfzafuVEvM+kNYCxp
EC6KITLb9g=

[DNH] Similarly, this should be broken as:
MEYwEAYHKoZIzj0CAQYFK4EEACIDMgACwDXKQ1pytcR1WbfqPaNGaXQ0RJnijJG1em8ZK
ilryZRDfNioq7+EPquT6l9laRvw

[DNH] and this should be:

QfmkoQWHEz4XngXUeFyDXliEo3eF6vhqD

And that looks like it isn't right but it's just Outlook. Really, if you break it at those places it'll all fit.
