Chapter 1127 (1/2)
”No.” Xiaoling negates Xiaotan's reasoning without thinking.
”Ha?” Xiaotan was stunned.
”Ha ha That's for sure. ” ”As a drunkard who is eager to open the cellar and come out to enjoy himself, he will not use too complicated encryption method,” Feng chuckled
”That's right.” Xiao Ling said, ”analyze the headmaster's mentality and you will understand If he could, he would like to write the eight digit password directly on the paper. That would be the most convenient. ” She said, pointing to the remote control with great skill, ”you see, he has put the remote control together with the two things needed for decryption, which shows that he is very clear When you are addicted to it, you don't have time to do anything too complicated. You just want to open the cellar quickly. ”
”Then why didn't he just set up a simpler password, or just copy the eight digit password on paper?” Guixiao then said again, ”in this way, he can open the wine cellar even when he is drunk in a daze.”
”That's right But at the same time of making it convenient for him, he must also take security into consideration. ” Xiaoling replied, ”after all, he's also a primary school principal. If alcohol abuse is fully exposed, he will lose his job. Otherwise, he doesn't have to build such a” secret cellar ”and install an entrance with a remote control.”
”Oh...” Ghost Xiao understands.
And Xiaotan then said, ”so He came up with this ”convenient and safe” way of putting all the things he needed to open the cellar in a drawer and encrypting them in some simple way. In this way Even if someone shows something in the drawer, they can't unlock the code in a short time. ”
”Ah It should be said that Under normal circumstances, people who have these three things don't think about ”decryption” at all, do they? ” Feng chuckled and said, ”we use the thinking and perspective of modern people and players to think about problems It's the first time to think about the use of these three things. But what from the point of view of the characters in the play? ” He made a meal. Again, ”you know, this script was born in the 1970s. At that time It's only more than ten years since the real civil wireless remote control was born; it's not until the 1980s that the infrared TV remote control that we are familiar with began to be popularized. So... Wireless remote control for people at that time. Obviously it's still a rarity. How many people can recognize the remote control in Japanese rural primary schools? To take it a step further, even if someone knows this is the remote control, then what? This person has to know at least two other things before he can think about ”decryption.”
At this point, Chueh held out three fingers: ”first, he needs to know that the principal has a secret cellar. In this way, he can think of what the remote control is used to control. Secondly, he has to know how the remote control works and the exact location of the cellar entrance Because it was acoustic technology, not infrared, there was no obvious exposed receiver at the entrance of the cellar. If the user doesn't know where the entrance is, he can't open the cellar even if the password is broken. ”
”By the way I just wanted to ask. ” Xiaotan hears this, turns to look at Xiaoling and says, ”how did you find the entrance?”
”I found it with the texture on the floor.” Xiaoling returns.
”Floor...” Small sigh while reciting, while looking down.
Indeed, the wooden floor used in the principal's office is better than any other area they have visited before. Not only are they laid thick and tight, but they are all patterned.
”Oh! I see. ” Two seconds later, an Yueqin suddenly realized Tao. ”One of the three tips in the ladies' room is used here.”
”Well.” Xiaoling nodded, ”the seemingly irregular graffiti on the wall of the women's toilet is exactly the same as the floor texture at the entrance of the wine cellar; when I was exploring in this room before, I felt that the floor pattern here seemed to be a little familiar. When I heard the head of the group said that he would knock the wall and floor inch by inch to find the entrance, I realized the problem.”
”Then The problem has come back. ” Two seconds later, Xiaotan said to Xiaoling, ”the eight digit password of” the encryption method is not complicated ”. What is it? ”
”42561o47.” next second, Xiao Ling reported the answer.
”Ha?” This time. The other five This is the reaction, even if you don't feel it.
”How did you figure it out?” Chueh first asked.
”It's easy, 1568 times 616512. The result is exactly a twelve digit number, 14276445o816... ” Xiaoling replied, ”and the eight numbers in the middle refer to the eight positions in the twelve digits. The sixth digit is 4, the third digit is 2, the eighth digit is 5, the fifth digit is 6, the eleventh digit is 1, the ninth digit is O, and then the sixth digit 4. Finally, number 4 7. In addition to the 6th digit that has been repeated once, there is no repetition of the numbers in the 7 positions listed in the total, that is, ”there are no two different positions pointing to the same number”, which is also in line with the logic of the password. ”
At the end of her speech, there was no sound
”Hello hello hello...” It took about five seconds for guixiao to respond, ”sister Let's not talk about that big pile in the back... ” He paused for half a second and asked with a surprised look, ”how do you do the multiplication between two six digits before you even turn on the calculator?”
”Mental calculation.” Xiaoling returns two words.
