	  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.

	  The focus is on:
	   - simplicity of configuration
	   - strong encryption and authentication methods
	   - powerful IPsec policies supporting large and complex
	     VPN networks

	  strongSwan provide many plugins. Only a few are presented
	  here.
