[[Category:Services]]
These NWM services are used for local-WLAN communications, NWM module handles regular wifi APs as well. These services are used for creating/connecting to networks, and for sending/receiving data over the network etc. NWM module uses the wifi SDIO hardware via the IO registers for this.
=NWM local-WLAN service "nwm::UDS"=
=NWM service "nwm::INF"=
=NWM service "nwm::SOC"=
=NWM service "nwm::SAP"=
=NWM local-WLAN [[StreetPass]] service "nwm::CEC"=
=NWM service "nwm::EXT"=
=NWM service "nwm::TST"=
=Local-WLAN WPA2 Passphrase Generation=
All local-WLAN communications have the WPA2 passphrase generated the same way with NWM module. The input data used with [[Process_Services|EncryptDecryptAes]] with [[PSPXI:EncryptDecryptAes|keytype1]] is a MD5 hash over an input passphrase. This input passphrase is fixed for Download Play(the input passphrase for [[StreetPass]] is unknown), it's unique per local-WLAN protocol. The CTR is a MD5 hash over the below 0x10-byte structure. The output from encrypting that data with AES-CTR is the final WPA2 passphrase.
