Line 20: − + − The Download Play protocol and all local-WLAN communications have the WPA2 passphrase generated the same way. The input data used with [[Process_Services|EncryptDecryptAes]] with [[PSPXI:EncryptDecryptAes|keytype1]] is a 0x10-byte hash over an input passphrase. This input passphrase is fixed for Download Play, it's unique per local-WLAN protocol. The CTR is a 0x10-byte hash over a 16-byte structure which among other data includes the host MAC address, and an ID which is normally from the application's uniqueID in the titleID.(The uniqueID used for Download Play is fixed however) The hex output from crypting that data is the final WPA2 passphrase. This 0x10-byte hash is unknown, however this might be MD5.+ − + − The WPA2 passphrase used for communications with the booted Download Play executable is a separate passphrase, generated using the above method where the input passphrase is a random hex string.

Download Play 协议和所以的本地无线通讯使用相同的WPA2加密机制。输入数据使用 [[Process_Services|EncryptDecryptAes]] 和 [[PSPXI:EncryptDecryptAes|keytype1]] 是一个 0x10-byte 哈希值. Download Play输入的口令是固定的，区别在于每一个本地无线协议。 CTR是一个0x10-byte 经过哈希的16-byte结构，包含了主机MAC地址, 正常应用的titleID中的uniqueID。(然而用于Download Play的uniqueID是固定的)。输出的十六进制加密数据是最终WPA2密码。这个有可能是MD5的0x10-byte哈希值是未知的。
引导Download Play可执行文件的wpa2通讯使用上述方法生成的随机十六进制字符串作为密码。
