Enter the flag in the format: flag{Ch33ri0z_R_his_FAV}.
There is memcmp(&favorite,myInput,14); function that compares the first 14 bytes of memory area &favorite and memory area myInput.
The favorite data is 4d 79 7c 70 7b 80 47 52 59 5c 4c 4e 4c 59.
Previously, there is for loop that adding our input with '\a', BELL character in C. So, our correct input should substract with '\a' first.
encoded_hex = b'\x4d\x79\x7c\x70\x7b\x80\x47\x52\x59\x5c\x4c\x4e\x4c\x59'
decoded = bytearray()
for byte in encoded_hex:
decoded_byte = byte - 7
decoded.append(decoded_byte)
payload = decoded.decode('utf-8')
print(payload)
# Fruity@KRUEGERInput the payload will result the flag.
