You need to actually find the password the program is expecting, changing instructions wont help you here.
I found the password (and it’s very clear that it IS the password) but for some reason root-me says "Just try again".
No idea what to do now :(

Bonjour, je suis totalement perdu dans ce challenge. Avec quel logiciel doit on ouvrir ce fichier? Je suis sous linux, ubuntu, j’ai utiliser objdump pour lire le fichier en assembleur. Auriez-vous des pistes? Merci

Look before the printf statement saying that u can validate with the password .There u can easily see the password in radare2 or gdb

@itai did you solve it?

I found the password, it’s very clear it’s correct — and by googling it I can find other writeups that have it, but it doesn’t get accepted. Must be a bug.
