libcharon-extra-plugins 5.5.1-1ubuntu2 (armhf binary) in ubuntu zesty

 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 extra plugins for the charon library:
  - addrblock (Narrow traffic selectors to RFC 3779 address blocks in X.509
    certificates)
  - dhcp (Forwarding of DHCP requests for virtual IPs to DHCP server)
  - certexpire (Export expiration dates of used certificates)
  - eap-aka (Generic EAP-AKA protocol handler using different backends)
  - eap-gtc (EAP-GTC protocol handler authenticating with XAuth backends)
  - eap-identity (EAP-Identity identity exchange algorithm, to use with other
    EAP protocols)
  - eap-md5 (EAP-MD5 protocol handler using passwords)
  - eap-radius (EAP server proxy plugin forwarding EAP conversations to a
    RADIUS server)
  - eap-tls (EAP-TLS protocol handler, to authenticate with certificates in
    EAP)
  - eap-tnc (EAP-TNC protocol handler, Trusted Network Connect in a TLS tunnel)
  - eap-ttls (EAP-TTLS protocol handler, wraps other EAP methods securely)
  - error-notify (Notification about errors via UNIX socket)
  - farp (fake ARP responses for requests to virtual IP address)
  - kernel-libipsec (Userspace IPsec Backend with TUN devices)
  - led (Let Linux LED subsystem LEDs blink on IKE activity)
  - lookip (Virtual IP lookup facility using a UNIX socket)
  - tnc (Trusted Network Connect)
  - unity (Cisco Unity extensions for IKEv1)
  - xauth-eap (XAuth backend that uses EAP methods to verify passwords)
  - xauth-pam (XAuth backend that uses PAM modules to verify passwords)
  - eap-aka-3gpp2 (EAP-AKA backend implementing standard 3GPP2 algorithm in software)
  - eap-dynamic (EAP proxy plugin that dynamically selects an EAP method requested/supported by the client (since 5.0.1))
  - eap-peap (EAP-PEAP protocol handler, wraps other EAP methods securely)
  - eap-sim (Generic EAP-SIM protocol handler using different backends)
  - eap-sim-file (EAP-SIM backend reading triplets from a file)
  - eap-sim-pcsc (EAP-SIM backend based on a PC/SC smartcard reader)
  - eap-simaka-pseudonym (EAP-SIM/AKA in-memory pseudonym identity database)
  - eap-simaka-reauth (EAP-SIM/AKA in-memory reauthentication identity database)
  - eap-simaka-sql (EAP-SIM/AKA backend reading triplets/quintuplets from a SQL database)
  - xauth-noauth (XAuth backend that does not do any authentication (since 5.0.3))
