WLAN_CCMP(4)

💅 wlan_ccmp — like, the AES-CCMP crypto bestie for 802.11 devices ✨

okay so real talk, this is wlan_ccmp(4) from the Kernel Interfaces Manual — a whole entire kernel interfaces moment, and honestly? iconic.

🌸 NAME 🌸

wlan_ccmp — AES-CCMP crypto support for 802.11 devices 🦋

✨ SYNOPSIS ✨

device wlan_ccmp

that's it. that's the whole vibe. one line, no notes 💅

🎀 DESCRIPTION 🎀

so the wlan_ccmp module is the one that handles all the AES-CCMP cryptographic requirements of the WPA and 802.11i protocols — like, the way that it just does that? highkey obsessed 🫶

it does encapsulation and decapsulation of CCMP-encoded 802.11 frames, and it optionally calculates the AES-CCMP cipher. yes bestie, optionally — it can be chill about it ✨

wlan_ccmp is an 802.11 cryptographic plugin module for use by the wlan(4) module. so it's giving supporting-character energy, but it's a main character kind of supporting character, iykyk 💖

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 hostapd. it literally just shows up when it's needed, no invitation required 🙈

and like, should the underlying network device not be capable of doing the AES-CCMP calculations in hardware, the wlan_ccmp module will do the work. not it stepping in to save the day 😭👑

⭐ STANDARDS ⭐

more information can be found in the IEEE 802.11, WPA, and 802.11i Standards 📚 — go read them, they're giving lore drops ✨

🦋 HISTORY 🦋

the wlan_ccmp driver first appeared in FreeBSD 6.0. a true 2004 legend, no cap 👑
