Banthar on 2019-07-17 20:17: Fun keygenme! You can kinda cheat it though. ### POSSIBLE SPOILER ### Since you got full control over argv's, you can force the shift to remove all calculated bits (if LSB is 0).

giving_mayer on 2019-07-26 12:50: I forgot the length of the executable had a ./ before so it increased the length by 2... Nevertheless a quite easy crackme.

markoto on 2019-09-08 15:24: Somehow I have gotten my keygen to work. In the debugger the absolute path of the file was included in the calculation. However, when the program is not run inside the debugger, it only considers its filename plus the ./ when calculating the length.
