💖 NAME 💖

wlan_ccmp — AES-CCMP crypto support for 802.11 devices 🦋

okay so bestie, this is a FreeBSD kernel interfaces manual page (the whole WLAN_CCMP(4) situation), and it's lowkey about the little crypto fairy that makes your Wi-Fi actually secure. let's get into it ✨

✨ SYNOPSIS ✨

device wlan_ccmp

that's it. that's the whole summoning ritual. iconic. 💅

🎀 DESCRIPTION 🎀

so the wlan_ccmp module is the one handling the AES-CCMP cryptographic requirements of the WPA and 802.11i protocols. she does encapsulation and decapsulation of CCMP-encoded 802.11 frames, and optionally calculates the AES-CCMP cipher. multitasking queen 👑

ngl, the wlan_ccmp module is an 802.11 cryptographic plugin module, and it exists for use by the wlan(4) module. they're a duo. 🫶

the way this works: the module gets 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. no cap, you don't even have to ask her to show up, she just knows. 🧚

and if the underlying network device is not capable of doing the AES-CCMP calculations in hardware, then the wlan_ccmp module will do the work herself. she said fine, i'll do it myself 💀💪

🌈 STANDARDS 🌈

more information can be found in the IEEE 802.11, WPA, and 802.11i Standards. go read them if you want the lore, iykyk 📚✨

👑 HISTORY 👑

the wlan_ccmp driver first appeared in FreeBSD 6.0. a legend since day one. 🎀

and that's the tea bestie 💖 this one comes to you from Debian, dated December 7, 2004, filed under WLAN_CCMP(4). slay, stay encrypted, and always do your AES-CCMP calculations responsibly. periodt. 💅✨🦋
