[nsp] NTP authentication keys

[atticus at satanic.org]

Does anyone know a way to enter encrypted NTP authkeys into a config?

'ntp-authentication key <0-9> md5' doesn't have a means to specify that
the key being entered is plain-text or encrypted, so it can't be
cut'n'pastered across devices (instead, the crypt text is md5'ed again).
Seeing as how this works for passwords in bgp, ospf, username, etc, my
only guess is that its an oversight...

Ideas?
