SUPERNOVA on 6:40 PM 11/04/2023: 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 6:55 PM 11/04/2023: @SUPERNOVA Yes, it gives repeatedly same values. So, i asked to the author whether he checked it or not.

aname on 8:53 AM 11/06/2023: possible to solve

sporta778 on 7:26 PM 11/08/2023: maybe username maybe solve this task.....

sporta778 on 7:27 PM 11/08/2023: )))) i do not know... how?

cnathansmith on 9:05 PM 11/08/2023: 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 9:11 PM 11/08/2023: 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

JMac2 on 2:18 AM 11/27/2023: @winapiadmin I assume this is your crackme and that you know it works and you know the passwords.

nightxyz on 11:41 PM 11/27/2023: @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.
