Does ntpd support SHA1 for symmetric keys? Looking at the docs it
suggests that the ntp.keys file should be generated with ntp-keygen
rather than by manual editing. Running ntp-keygen creates a file with
both MD5 and SHA1 keys, but when I try to use them ntpd says "invalid
key type" for all of the SHA1 keys. Not to mention I never heard anyone
say not to edit the ntp.keys file by hand. Am I misunderstanding the
whole thing?
