hxm on 2026-07-22 11:21: @michaelsrtsrt this challenge appears to be bugged. "real word_real word" is 19 bytes long, but the putchar loop is hardcoded to process only 16 bytes. 0x14000AC80 produces a fixed hash then than hash (similar to splitmix64.c ) then it is used to get the flag chars. fix your crackme sir.

michaelsrtsrt on 2026-07-22 14:11: @hxm updated description to better show the exact character amount for less confusion
