.Sh NAME
|
|
.Nm wlan_tkip
|
|
.Nd TKIP and Michael crypto support for 802.11 devices
|
|
.Sh SYNOPSIS
|
|
.Cd "device wlan_tkip"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
module handles the TKIP and Michael cryptographic requirements of the
|
|
WPA and 802.11i protocols.
|
|
It does encapsulation and decapsulation of TKIP-encoded 802.11 frames
|
|
and optionally calculates the TKIP cipher and Michael MIC.
|
|
The
|
|
.Nm
|
|
module is an 802.11 cryptographic plugin module for use by the
|
|
.Xr wlan 4
|
|
module.
|
|
This module is automatically loaded if a TKIP 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 TKIP
|
|
and/or Michael calculations in hardware, the
|
|
.Nm
|
|
module will do the work.

|
|
.Nm
|
|
driver first appeared in
|
|
.Fx 6.0 .
