Passwords are a kind of information.
Don't let the seemingly random string of numbers fool you; behind those numbers, there must be some deep meaning, or perhaps... a deep meaning that has been artificially assigned.
Passwords that have no meaning at all are not non-existent, but they are quite rare. Most passwords set by people have a unique significance or a unique story.
"So, let's not brute force it just yet."
Lin Xian took out the password diary from the coffin, and placed it next to the album and the old videotape:
"Since it's just a four-digit password, there are only 10,000 possibilities. Even if I try each one, it won't take me more than a few hours to figure it out."
"A four-digit password isn't like an eight-digit one... it's very easy to crack; it's just a matter of hand speed and patience. I tried earlier, and although the lock has been sitting for over twenty years, it's still smooth and quick to work."
