IPsec is the Internet Protocol Security and uses strong cryptography to provide both authentication and encryption services.  These services allow you to build secure tunnels through untrusted networks.  Everything passing through the untrusted net is encrypted by the ipsec gateway machine and decrypted by the gateway at the other end of the tunnel.  The resulting tunnel is a virtual private network or VPN. This package contains the daemons and userland tools for setting up Libreswan.
