29.Dt WLAN_CCMP 4
30.Os
31.Sh NAME
32.Nm wlan_ccmp
33.Nd AES-CCMP crypto support for 802.11 devices
34.Sh SYNOPSIS
35.Cd "device wlan_ccmp"
36.Sh DESCRIPTION
37The
38.Nm
39module handles the AES-CCMP cryptographic requirements of the
40WPA and 802.11i protocols.
41It does encapsulation and decapsulation of CCMP-encoded 802.11 frames
42and optionally calculates the AES-CCMP cipher.
43The
44.Nm
45module is an 802.11 cryptographic plugin module for use by the
46.Xr wlan 4
47module.
48This module is automatically loaded if an AES-CCMP key is configured;
49typically by a WPA supplicant program such as wpa_supplicant,
50or a WPA authenticator program such as
51.Nm hostapd .
52Should the underlying network device not be capable of doing the AES-CCMP
53calculations in hardware, the
54.Nm
55module will do the work.

58.Xr wlan_tkip 4 ,
59.Xr wlan_wep 4
60.Sh STANDARDS
61More information can be found in the IEEE 802.11, WPA, and 802.11i Standards.
62.Sh HISTORY
63The
64.Nm
65driver first appeared in
66.Fx 6.0 .
