I can't comment with any authority on product road-map (that's above my pay-grade) but I can speculate that we probably would support "S256" eventually. On Wed, Feb 18, 2015 at 10:33 AM, Hannes Tschofenig < hannes.tschofe...@gmx.net> wrote: > Thanks Brian for pointing me to Section 4.4.1 and to t

It was Google that wanted S256 to be mandatory for the AS to support. That makes it easier for the client. S256 is relatively new so not being supported yet is not surprising. Sent from my iPhone > On Feb 18, 2015, at 12:15 PM, Torsten Lodderstedt > wrote: > > We don't plan to support s25

We don't plan to support s256 Basically, I don't see a need to. Plain already mitigates the threat, spop/tcse had been designed to mitigate - an app intercepting the code response of a public client. Am 18. Februar 2015 18:33:17 MEZ, schrieb Hannes Tschofenig : >Thanks Brian for pointing me t

Thanks Brian for pointing me to Section 4.4.1 and to the MTI for "S256". While this is good from a security point of view I am wondering whether anyone is actually compliant to the specification. Neither PingIdentity nor DT implements the S256 transform, if I understood that correctly. Are you guys

There's a bit of MTI talk tucked into https://tools.ietf.org/html/draft-ietf-oauth-spop-10#section-4.4.1 that perhaps needs to be expanded and/or placed somewhere else. On Wed, Feb 18, 2015 at 8:33 AM, Hannes Tschofenig < hannes.tschofe...@gmx.net> wrote: > Thanks for the info, Torsten. > > Your

Thanks for the info, Torsten. Your feedback raises an interesting question, namely what functionality the parties have to implement to claim conformance to the specification. Quickly scanning through the specification didn't tell me whether it is OK to just implement the plain mode or whether bot

Hi Hannes, our implementation supports the "plain" mode only. We just verified compliance of our implementation with the current spec. As the only deviation, we do not enforce the minimum length of 43 characters of the code verifier. kind regards, Torsten. Am 17.02.2015 17:48, schrieb Hanne

When we did the implementation there was no S256 transformation defined or made MTI for the server. I'm pretty sure it was http://tools.ietf.org/html/ draft-sakimura-oauth-tcse-03 Thus, our server supports only the "no transformation" (as it was called then) or the "plain" code_challenge_method (a

Hi Torsten, does this mean that your implementation is not compliant with the current version anymore or that you haven't had time to verify whether there are differences to the earlier version? Ciao Hannes On 01/31/2015 05:34 PM, Torsten Lodderstedt wrote: > Deutsche Telekom also implemented a
