strongSwan is an OpenSource IPsec implementation for the Linux operating system. It is based on the discontinued FreeS/WAN project and the X.509 patch which we developped over the last three years. In order to have a stable IPsec platform to base our future extensions of the X.509 capability on, we decided to lauch the strongSwan project.

The focus is on

1.simplicity of configuration

2.strong encryption and authentication methods

3.powerful IPsec policies supporting large and complex VPN networks

The maintainer of the strongSwan project is Andreas Steffen, who is a professor for security in communications and head of the Institute for Internet Technologies and Applications at the University of Applied Sciences Rapperswil in Switzerland and president of the consulting firm strongSec GmbH.
