Improving OpenIDs use of cryptography 1 - using a MAC

[Jean-Luc Delatre]

About the general idea of "improving" the protocol.

Why not turn it the other way around?

Among known protocol proposals which have already been published and 
reviewed like in:
http://sky.fit.qut.edu.au/~choo/lounge.html

Or even among very recent ones:
http://www.di.ens.fr/%7Epointche/pub.php

Pick one which is "close enough" to the already existing OpenID, not 
overly complicated and not requiring too heavy computations
(it is mostly the prime numbers generation which "kills" and has to be 
delegated or pre-computed)
and *stick to the script*!!!

I don't really trust "homebrew authentication" .

And, to repeat myself, a seemingly obscure algorithm is not a problem if 
it fits in few lines of code and is not too heavy on number crunching 
(all good ones are, but there are degrees in the pain...)

So, could Paul or Imran or whoever else has the required skills have a 
glance at this path?

Cheers,

JLD
