<p class="Pp">The <code class="Nm">wlan_tkip</code> 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
    <code class="Nm">wlan_tkip</code> module is an 802.11 cryptographic plugin
    module for use by the <a class="Xr">wlan(4)</a> 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 <code class="Nm">hostapd</code>. Should the underlying network
    device not be capable of doing the TKIP and/or Michael calculations in
    hardware, the <code class="Nm">wlan_tkip</code> module will do the work.</p>
