42CTF Secure Vault

Published date : Sept. 10, 2021, 8 p.m.
I heard that 42ctf is hiding a lot of money in a military-grade vault, but I can't unlock it.
Send me the key file corresponding to 42ctf and I'll transfer you 50% of the money.
You'll find the vault firmware below.

*Flag is 42ctf{md5 of the key file}*
