Umm… someone explain this code please?
Bit shift magic.
My guess is that all the individual characters of Hello World are found inside the 0xC894 number. Every 4 bits of
xshows where in this number we can find the characters for Hello World.You can read x right to left. (Skip the rightmost 0 as it’s immediately bit shifted away in first iteration)
3 becomes H 2 becomes e 1 becomes l 5 becomes o
etc.
I guess when we’ve exhausted all bits of x only 0 will be remaining for one final iteration, which translates to !
Too readable. You've gotta encode the characters as the solutions of a polynomial over a finite field, implemented with linear feedback on the bit shifts. /s
