All UDS local-WLAN communications have the CCMP key for data encryption generated via NWM module. The CCMP key passed to nwm::CEC commands(stored in a 0x44-byte input structure) for [[StreetPass]] is generated by the CECD 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]], 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 CCMP key.

The output from encrypting that data with AES-CTR is the final CCMP key. This passphrase is a raw input buffer: while the passphrase specified by user-processes is normally a string with the NUL-terminator included, it can be anything(like the [[DLP_Services|WirelessRebootPassphrase]] for example).
