libcharon-extauth-plugins binary package in Ubuntu Mantic amd64

 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.
