Task: 64-bit PIE keygen crackme that compares hex serial input against transform_rand_value(rand()) where the PRNG is time-seeded, giving one attempt per run so the leaked serial cannot be replayed. Solution: NOP the jne (75 18 -> 90 90) at file offset 0x10f9 that guards the print-flag function, then run the patched binary under Docker amd64.
