.Dd December 7, 2004 .Dt WLAN_CCMP 4 .Os .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 .
