+.Sh NAME
+.Nm wlan_ccmp
+.Nd AES-CCMP crypto support for 802.11 devices
+.Sh SYNOPSIS
+.Cd "device wlan_ccmp"
+.Sh DESCRIPTION
+The
+.Nm
+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
+.Nm
+module is an 802.11 cryptographic plugin module for use by the
+.Xr 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
+.Nm hostapd .
+Should the underlying network device not be capable of doing the AES-CCMP
+calculations in hardware, the
+.Nm
+module will do the work.
+.Sh SEE ALSO
+.Xr wlan 4 ,
+.Xr wlan_tkip 4 ,
+.Xr wlan_wep 4
+.Sh STANDARDS
+More information can be found in the IEEE 802.11, WPA, and 802.11i Standards.
+.Sh HISTORY
+The
+.Nm
+driver first appeared in
+.Fx 6.0 .
