NAME

     wlan_ccmp — AES-CCMP crypto support for 802.11 devices

SYNOPSIS

     device wlan_ccmp

DESCRIPTION

     The wlan_ccmp module handles the AES-CCMP cryptographic requirements of the WPA and 802.11i
     protocols.  It does encapsulation and decapsulation of CCMP-encoded 802.11 frames and
     optionally calculates the AES-CCMP cipher.  The wlan_ccmp module is an 802.11 cryptographic
     plugin module for use by the wlan(4) module.  This module is automatically loaded if an AES-
     CCMP key is configured; typically by a WPA supplicant program such as wpa_supplicant, or a
     WPA authenticator program such as hostapd.  Should the underlying network device not be
     capable of doing the AES-CCMP calculations in hardware, the wlan_ccmp module will do the
     work.
