load ECDSA public key from certificates
I was trying to build it against OpenSSL 1.1.0 and hit several issues
with the eighth iteration patch:
* I would say that the OpenSSL version and functions detection step
should happen during the configure phase, rather than during build on
top of each file using ECDSA keys.
* OpenSSL 1.1.0 obsoletes most of the ECDSA_* structures and functions
in favor of generic EC_KEY*. The OpenSSL 1.1.0 method structure is
called EC_KEY_METHOD. Doing this in compatible manner will be pain.
* The functionality of pulling the public key from X.509 certificate
is completely missing.
In the attached patch, there is a snippet to load ECDSA public keys
from certificates as my small contribution. Feel free to include it in
your patch.
I somehow solved the OpenSSL 1.1.0 compatibility, but probably for the
price of breaking backward compatibility with OpenSSL 1.0.x or
LibreSSL.
I put together some modifications to the original patch and built it in
copr for Fedora if somebody is interested and would like to try:

So far my testing looks fine, keys on my yubikey are recognized and I
can authenticate using them successfully.
