| This is how they generate the password (the XOR stuff): | |
| pwd[0] = (cid[3]>>8 | cid[2]<<24) ^ 0x7E98C617u; // 0x17C6987E | |
| pwd[1] = (cid[2]>>8 | cid[1]<<24) ^ 0xDEED0144u; // 0x4401EDDE | |
| pwd[2] = (cid[1]>>8 | cid[0]<<24) ^ 0x68C51A37u; // 0x371AC568 | |
| pwd[3] = (cid[0]>>8) ^ 0x62B5FF65u; // 0x65FFB562 | |
| The shifting around is just because i have the CID laid out differently than what they used: | |
| / CID is in 128 bit mixed endian (MSB in cid[0], little endian words). | |
| / Shift the CID back into the screwed up format TMIO uses and apply key |
