This program relates to an obsolete Pay TV encryption system,
and is not intended to aid in pay television piracy in the present day.
Back in the day it was possible to use this algo, and it's signature algorithm counterpart to produce programs to maintain pirate tv cards,
or to produce programs that run on the cards themselves.
This is just a little PSP demo with the keys from Rashid's original document
(included) hard coded into the program.
For the first time, a live visual decryption and re-encryption of the Plain Master Key can be seen this way.
The "11 11 11 11 11 11 11 11 11 11" Hex Master Key from the
example doesn't give too much of a visual display,
but the second example in this YouTube video:
uses a different key set which is also made up from arbitrary byte values.
The PSP demo is a user mode program,
and has been tested with 3.52 and 1.50 kernels on 3.52 M33 custom firmware.
