Generating cryptographic files for NTPv4 authentication using the ntp- keygen program

The ntp-keygen program generates files with cryptographic material which are used for the NTPv4 authentication mechanisms. It can generate message digest keys which are employed in symmetrical encryption. It also generates host keys, signature keys, certificates and identity keys which are used in "autokey" cryptography with public keys.

You will find a description of the call parameters, for example, in the HTML documentation.
