This is an automated email from the git hooks/post-receive script.
dtucker pushed a commit to branch master
in repository openssh.
commit c4b3a128954ee1b7fbcbda167baf8aca1a3d1c84
Author: dtucker at openbsd.org <dtucker at openbsd.org>
Date: Thu Jan 23 02:46:49 2020 +0000
upstream: Remove unsupported algorithms from list of defaults at run
time and remove ifdef and distinct settings for OPENSSL=no case.
This will make things much simpler for -portable where the exact set
of algos depends on the configuration of both OpenSSH and the libcrypto
it's linked against (if any). ok djm@
