Hi Nils,
This is excellent. It means I don't need to worry about it; which
dramatically improves my patience levels. :)
(Otherwise I'd have worry about finding time to dig into the code etc
and not being an openssl-dev type yet that might be more time than
I'd like).
I'll give the patches a shot once I get my head above water. I've a
plane trip coming up and that sounds like a good time for it.
Thanks,
- max

(Hello, I'm asking again. Please let me know if you think this
would be more appropriately addressed to the openssl-dev list or
something.)
In summary: Is it possible to use sha256 when generating an ecdsa
certificate?
I'm currently working on it so please have a little more patience ;-)
If you can't wait to generate a ecdsa-with-sha256 certificate try
the attached preliminary patch.
Cheers,
Nils
