In principle, NTP Autokey can use certificates generated by OpenSSL or 
by other certificate authorities (CA); however, there are some very 
minor details with these certificates, including the sequence number and 
use of the X.500 extension fields. Ideally, the CA would run the Autokey 
protocol and serve as the TH itself, which would be consistent with the 
TC model. Absent that, the choice is to use the certificates generated 
by the ntp-keygen program.
