FireWall KNock OPerator - shared library

The FireWall KNock OPerator implements an authorization scheme called Single Packet Authorization (SPA), based on Netfilter and libpcap.

Its main application is to protect services such as OpenSSH with an additional layer of security in order to make the exploitation of vulnerabilities (both 0-day and unpatched code) much more difficult.

The authorization server passively listens for authorization packets via libpcap, so there is no service listening for network connections on the traditional port. Access to a protected service is only granted after a valid encrypted and non-replayed packet is detected.

This package provides the runtime library for fwknop (written inC).
