Description

Not much to say there. Valid solution is a keygen that produces a valid key for any given name. Binaries for Linux and Windows are provided. Plain C, no symbols stripped, compiled with -O0, so should be fairly easy to follow. Difficulty is medium. Or perhaps easy for someone with some math knowledge. Here are some valid keys: Name: hekliet Key: 3fec806bc9ce82d4c00ee01af273a0b5 Name: crackmes.one Key: 4003ce8255e1955e3fec45f6a879aa89 Name: Guybrush Threepwood Key: 400e09a63ee6d3a2bfd94d31f7369d10

r1 and r2 must be quadratic roots of r² + a*r + b = 0

what an interesting chall, but I see that we just find out 16B-first and repeat them in last after KeyGen() func, we can also pass it. btw, you can read WU on my website and give me one star if you want ^^ Web : https://kajrivn.github.io/Blog/posts/hekliets_keygenme/
