get the password	DO NOT READ IF YOU DO NOT WANT SPOILERS! I may have figured it out, there seems to be a lot of functionality that is not really used. Maybe filler code to throw us off? Seems the password is a fixed value added by 1, however, it is put into the heap at a random location within the get_pwd(). If my understanding is correct I will try to write a solution and explain within it.	2019-03-11 23:44
jumpjumpjump	@cbm-hackers I did post solution :) How close was the reverse engineered code? I think strcat_str() is pretty same as yours, everything the idea is there.	2018-12-27 18:33
