==Incorrect Key Schedule description==

The key schedule is incorrectly described. The 25 bit left rotate is not applied to the 128 bit key until after the full 128 bits are used in the key. This happens in the middle of the second round (96 bits are used for the first round, the remaining 32 bits are used in the second round.) The rotate left operation is only performed a total of 6 times in the key schedule.
