49 reads its keys from a file specified using the
51 command line option or the
53 statement in the configuration file.
54 While key number 0 is fixed by the NTP standard
56 and may not be changed,
57 one or more keys numbered between 1 and 65534
58 may be arbitrarily set in the keys file.
62 The key file uses the same comment conventions
63 as the configuration file.
64 Key entries use a fixed format of the form

108 What follows are some key types, and corresponding formats:
114 The key is 1 to 16 printable characters terminated by
120 (which is the "start of comment" character).
136 The key is a hex-encoded ASCII string of 40 characters,
137 which is truncated as necessary.
142 Note that the keys used by the
