You must be kidding me, you are gonna use one of the internal streams
that never see daylight because they are xor together, they are also
unknown without the key.

But you tell me if i give the key so you can calculate 255 values in
one of the permutation legs, you are able to calculate number 256 in
an permutation with unique values you guys are really somekind of
*SUPER GENIOUS* savant and retarded one but yet......

Hehe I wonder who is fooling who here, but you people can not be to
bright, i give you 255 bytes from the any round of my PRNG (YES THAT
IS THE ONE THAT WORKS ON THE PLAIN TEXT) better up i give you (2
gigabytes output from my PRNG including the 255 first values in the
last round and *YOU STILL WILL NOT BE ABLE TO TELL ME WHAT VALUES IN
THE KEYSTREAM*. That is fact people not some cooked up imagination
like yours.
