nightxyz on 2023-11-03 20:59: Did you check out ? does it work ?

SUPERNOVA on 2023-11-04 18:40: I dont think its possible to solve this, for each odd value of atoi you get: 5535546021854586238, and for even one you get: 8530211075909953085 which arent the same as 8489035907084405855.

nightxyz on 2023-11-04 18:55: @SUPERNOVA Yes, it gives repeatedly same values. So, i asked to the author whether he checked it or not.

aname on 2023-11-06 08:53: possible to solve

sporta778 on 2023-11-08 19:26: maybe username maybe solve this task.....

sporta778 on 2023-11-08 19:27: )))) i do not know... how?

cnathansmith on 2023-11-08 21:05: SUPERNOVA nailed it. The only thing you can control is whether the password is odd or even, and neither evaluates to a correct solution

cnathansmith on 2023-11-08 21:11: It also crashes because 7*8 bytes are being overwritten past the result buffer that you also can't control beyond choosing one set of values or the other

winapiadmin on 2023-11-14 13:14: I'm forgotten, but we can patch it!

JMac2 on 2023-11-27 02:18: @winapiadmin I assume this is your crackme and that you know it works and you know the passwords.

nightxyz on 2023-11-27 23:41: @JMac2 I think he made a mistake and kept us busy for nothing. He wants to cover up his mistake by saying that he forgot to say "You can patch". A virtuous person should accept his mistake and say it clearly.
