Apologies for getting into this thread (I do not understand most of the

Yes, S() is surjection. Specifically, it is defined over X:={x | len(x) =<

the Domain is constrained to D, which is equal to R. That's what I was

Hi Sergey,
If we change from a SHA256 function over the code_verifier to a SHA256 over the
concatenation of the code_verifier and client_id, that would be defined in the
spec.
We would not do both, and the salt would not be a real random. There would be
many instances of a client all using th

Hi John
Thanks for going over it again and explaining it all so nicely, even I
do understand it now (I'd like to think so :-)) why using a client id as
a salt does not add much to the signature strength.
I thought the idea was consider to introduce some extra randomization,
where say even mult

Hi,
I reviewed draft-Ietf-oauth-dyn-reg-20 and have the following questions before
we move this to IETF last call.
Sect 2, Has there been any consideration in the WG of using alternate auth
methods from HTTPAuth like HOBA? I realize this is referencing Oauth defined
methods from the framework
