strongSwan charon library (extended authentication plugins)

The strongSwan VPN suite uses the native IPsec stack in the standard Linux kernel. It supports both the IKEv1 and IKEv2 protocols.

This package provides extended authentication plugins for the charon library:

 - eap-mschapv2 (EAP-MSCHAPv2 protocol handler using passwords/NT hashes)
   Used for client side to connect to some VPN concentrators configured for
   Windows 7+ and modern OSX/iOS using IKEv2 (identify with public key,
   authenticate with MSCHAPv2).
 - xauth-generic (Generic XAuth backend that provides passwords from
   ipsec.secrets and other credential sets)
   Used for the client side to connect to VPN concentrators configured for
   Android and older OSX/iOS using IKEv1 and XAUTH (identify with public key,
   authenticate with XAUTH password).

These are the "not always, but still more commonly used" plugins, for further needs even more plugins can be found in the package libcharon-extra-plugins.
