Comment (by jchevali):

 Today for the first time following PR-415 I'm able to bring a secured
 hidden service up without the server crashing (you can't blame if before I
 thought the server was crashing due to a padding intolerance, since that's
 what it appeared to do: it'd only crash if the public key that protected
 the service was unpadded).

 Unfortunately I'm still not able to check that a client can connect to
 that, since the client is still showing the error (from comment nº 4),
 even though it has a matching private key for the HS and the server can
 bring it up.

 I guess I might have to wait for a further pull request (written for a
 bug, perhaps, still to be logged) to be able to use a secured hidden
 service end-to-end for the first time.
