Originalnachricht

Name        : openswan
Product : Fedora 14
Version : 2.6.33
Release : 3.fc14
URL : http://www.openswan.org/
Summary : IPSEC implementation with IKEv1 and IKEv2 keying protocols
Description :
Openswan is a free implementation of IPsec & IKE for Linux. 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
Openswan. It supports the NETKEY/XFRM IPsec kernel stack that exists
in the default Linux kernel.

Openswan 2.6.x also supports IKEv2 (RFC4306)
