About Network Time Protocol
The Meinberg NTP package provides a GUI setup program for Windows which installs the NTP service and associated executable programs that have been compiled from the original public NTP source code available at the NTP download page at ntp.org.
The GUI installer also contains the corresponding HTML based NTP documentation, as well as the libcrypto DLL from the OpenSSL project, which is required to create or check signatures of the NTP network packets, if the symmetric or public key authentication feature is used.
