Comment (by atagar):

 Thanks irl. Sunk some time into this but unfortunately I'm a bit stuck. I
 began with sha256 digests of extrainfo descriptors because we can easily
 check their corresponding server descriptor to see if we got the correct
 hash or not.

 A commit that attempts to do this is available in the 'sha256_digest'
 branch of my personal repo...

 https://gitweb.torproject.org/user/atagar/stem.git/commit/?h=sha256_digest&id=70d6e35047b3dc15fcd8438a9eb824e0105ed364

 Unfortunately though the spec seems pretty clear I'm somehow not matching
 what server descriptors expect. Would you mind seeing if you can spot what
 I'm buggering up here?
