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.
