SofiaB8921 on 2022-07-23 19:00: Can someone help me solve this? I found the function that generates the password from the username and figured out how it works but I don't understand it. It is adding both a character and an integer cast to a character and another character all together and setting it to one index of the password result. I don't understand how it casts it or how you can add all of them and get one value for the index of the password.

shadow299 on 2022-08-06 07:40: hey guys, i solved this crackme by just reversing the jump. after this every username and password is valid.

xin999 on 2022-08-16 19:05: i guess you could just change the jne instruction to jmp and jump to 0x0040149D, if thats a dumb way to solve it im sorry im new to this

jin246 on 2022-10-03 17:28: **********SPOILER*************** I solved it by changing the eax to 1 right before the jne 1 to it loads the solved state and not jump to the fail state

jin246 on 2022-10-03 17:36: does this count at patching? (sorry, I'm new to this)
