Re: [OAUTH-WG] Advertise PKCE support in OAuth 2.0 Discovery (draft-jones-oauth-discovery-00)

[Dominick Baier <[e-mail]>]

I also added a support for it to our .NET client library.

We are now live with this change:

 

https://accounts.google.com/.well-known/openid-configuration

 

I'm glad we all reached a consensus on how this param should work, and what it should be called, and thank you Mike for revising the draft! My ask now is that we don't revisit this decision, unless for extremely good reasons, as we don't want to break clients who will start using this.

Thanks Mike, looking forward to the update. I reviewed the other thread.

I'll add it to the discovery draft in the next day or so.  Also, please see my questions in the message "[OAUTH-WG] Discovery document updates planned". I was waiting for that feedback before doing the update.

Thanks,

OK great! It seems that we have consensus on this. So this is what we plan to add to our discovery doc, based on this discussion:

 

"code_challenge_methods_supported": ["plain","S256"]

 

What are the next steps? Can we we add it to https://tools.ietf.org/html/draft-jones-oauth-discovery directly? I see that the IANA registry created by that draft is "Specification Required", but PKCE is already an RFC without this param being registered.

Yes sorry.   code_challenge_method is the query parameter so code_challenge_methods_supported

The code_challenge and code_challenge_method parameter names predate calling the spec PKCE.  

 

Given that some of us deployed early versions of PKCE in products and opensource to mitigate the problem before the spec was completed we decided not to rename the parameter names from code_verifier_method to pkce_verifier_method.  

 

For consistency we should stick with code_verifier_methods_supported in discovery.

 

To clarify, did you mean "code_challenge_methods_supported"?  That is, building on the param name "code_challenge_method" from Section 4.3?

"code_challenge_methods_supported" definitely works for me.

 

Any objections to moving forward with that? I would like to update our discovery doc shortly.

Ah, OK. That's actually reasonable.

I prefer “code_challenge_methods_supported”, since the registered parameter name is “code_challenge_method”, not “pkce_method".

Seems like we agree this should be added. How should it look?

Two ideas:

"code_challenge_methods_supported": ["plain", "S256"]

 

or

 

"pkce_methods_supported": ["plain", "S256"]

Good point.  Now that PKCE is a RFC we should add it to discovery.
