Scrambling stage: Will loop through the table crated before (loop of 0x100 iterations, again) creating modifying each value with semi-random bytes. In order to create this semi-random bytes, the RC4 key is used. RC4 keys can be between 1 and 256 bytes in length, however it is usually recommended that it is above 5 bytes. Commonly, RC4 keys are 16 bytes in length.
