Birds of Randomness

HackTheBox

The server generates a random 256-bit "ticket number" as a seed for a Wichmann-Hill PRNG (three coupled LCGs with moduli 30269, 30307, 30323). It rotates the PRNG until all three components (x, y, z) are prime, computes scalar `d = x·y·z`, and returns the EC point `d·G` as the "departing station coo
