Chapter 10 Limit Reasoning_2

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.

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."
