OpenNTPD with OpenSSL support

OpenNTPD daemon with OpenSSL implementation & flexible configurability

See also my blog post on fjordtek.com.

Added features

• Implemented OpenSSL support. Either LibreSSL or OpenSSL can be used.

• Many previously hardcoded values are now configurable via conf file.

• Implement UDP & TCP port selection for multiple options.

• Implement custom user agent string support for constraints.

• Improved log entries interpretation.

• Updated manual.
