# Add back openssh MACs that got removed from defaults
|
|
# for backwards compatibility
|
|
#
|
|
# NixOS default openssh MACs have changed to use "encrypt-then-mac" only.
|
|
# This breaks compatibilty with clients that do not offer these MACs. For
|
|
# compatibility reasons, we add back the old defaults.
