Six years have gone since md5 is considered broken. I find the fact that
MD5 is still configured as the default HMAC alarming in itself as it
indicates a lack of proactiveness that we so bitterly need in this day
and age of heartbleeds and the like. I consider it a faulty default.
This is a broken primitive. It needs to be phased out so it should not
be the default configuration. That's just common sense. No RFC can beat
that ;-) .
