Chapter 87: Password Storm (II)
Judging from the photocopy, the original was an A4 paper that had been burned. There were a bunch of numbers and letters on the paper, and the letters were divided into uppercase and lowercase. There were several holes in the paper, and some words were missing. There was also a note . The note had an email address and an event description. Thresh said that when he arrived, the password paper was already burning, and he stepped on the paper to put out the flames and broke it at the same time.
Liang Xi knew it was a difficult code as soon as he saw the dense code. One type of code is called a universal code, such as Morse code. Another type is called an agreed code, such as the book "Detective Twist" which is agreed to be the basis of the code. The number 25 is the page number, and the letter Z represents the first word starting with Z. After translating and combining, a group of words can be obtained. The agreed code has infinite variations and is basically impossible to crack.
There is also a semi-conventional cipher, such as agreeing to remove even-numbered letters in each row. In ancient times, the silver bills of money houses were semi-conventional ciphers. There might be a typo or a specific word written on the silver bill to prove that the silver bill was authentic. Semi-conventional ciphers can be cracked.
In addition, there are various kinds of codes, such as the password and decoder are separate. The decoder is a piece of paper with holes, which covers the password. Reading the holes reveals numbers and letters, which can be pieced together to form a sentence.
Under current technology, paper passwords are not usually used unless it is in an environment where it is inconvenient to pass messages. Similar environments include: prison letters, and before a large operation where the police suspect there is a mole, they will gather all the action personnel, confiscate their mobile phones, and monitor each other. Another possibility is that A and B do not know each other, and they have a communication station, such as a bench in the park. A goes to the park and sticks the password on the bottom of the bench. B takes the password and gets the order or instruction after decrypting the password. This is usually done when A thinks he is being monitored and the monitor wants to catch a big fish.
Liang Xi judged that regardless of whether Thresh was fooling around or not, the password might really be related to the Holy Flag. But how to crack it? Liang Xi called the driver and bodyguard Willy: "Please go to the detective agency."
…
Arriving at the detective agency, Liang Xi and Bobby found the ancient red scripture and began to try to crack the code. Liang Xi read: "Page 25, third row, word starting with C. Page 31... all together."
Poppy said, "Foresee the Brave Kettle."
Pointless.
Liang Xi started the method of subtraction. For example, for the number 25abc, 2 means skipping two letters and getting bc. When the second number appears, skip it again according to its number. The subtraction method ends just as it begins because there is a capital letter.
For the next hour, Liang Xi and Poppy tried various combinations, but to no avail. Poppy lost patience and asked, "Is Thresh playing tricks on us?"
Liang Xi said, "There must be a trick. But it's meaningless for us to waste a few hours on him. Poppy, I think the direction of cracking is wrong. People like Thresh are very smart. He likes complex passwords. Most criminals are not very smart, and the passwords should be relatively simple ."
Liang Xi picked up the ruler and measured it on the paper for a while, then said in surprise: "Look."
The first number is 25. Liang Xi puts one end of the ruler on the second letter, and then on the fifth letter in the second row. Wherever the ruler goes, he forms a sentence: 11:00 p.m. on the 6th. The capital letters are not meant to be mysterious, but to explain it directly. AM and PM are abbreviations for morning and afternoon. PM here means 11:00 p.m. Today is the 6th.
With this breakthrough, everything became simple. With the ruler, I quickly got most of the information: 11:00 p.m. on the 6th, second floor of the underground parking lot of Supreme Plaza, license plate number 1234. I say most of it because the original was burned and damaged. There was also a piece of information with only the number 4 and the word "car seat cushion".
Bobby said happily: "The Invincible East has reappeared in the arena."
Liang Xi said: "No, Dongfang Bubai can only fight against bad guys. You can't use your bodyguards when you have resources."
Bobby was unhappy: "This is not fun."
Liang Xi picked up the phone and said, "Captain Liu... I just got back... I've been in a bad mood lately. Can you pick a team to try your luck with me?"
Liu Zhen readily agreed: "Okay, let's go with Baker's team. By the way, Baker has been in a bad mood these days."
Liang Xi asked curiously: "What happened to him?"
Liu Zhen: "Baker advanced to the interview without selection, but was rejected by Blade Boss."
Liang Xi said: "Poor Baker."
Liu Zhen: "Tell me a place and time."
…
Supreme Plaza is a famous commercial plaza. Its six-storey shopping mall brings together various food, drink and entertainment activities. On Fridays, Supreme Plaza is one of the favorite places for white-collar workers who stay out late at night along the nearby commercial streets.
There are two floors in the underground parking lot. The first floor was already full early. There were many cars on the second floor, but there were still empty spaces. After nine o'clock, many parents who came to the Supreme Plaza with their children and people who had just watched the movie left one after another. With the arrival of ten o'clock, the catering industry went off work, and the number of cars in the underground second floor parking lot became much sparser. At the same time, the number of people going to the night entertainment venues on the fifth and sixth floors began to increase sharply.
Cars were coming in and out, and the two car passages on the second underground floor leading to the first floor were constantly busy.
Near Channel A, Liang Xi and Baker were sitting in a car drinking coffee and chatting. Near Channel B, Owen and Bobby were sitting in a bulletproof luxury car and chatting.
Liang Xi and Baker talked about Isa of Blade, and Baker complained: "This woman sent people to search my house early in the morning, saying that I was disorganized, too casual, and careless. I am a single man who has worked hard all day. Do I have to be restricted when I go home?"
Liang Xi asked: "Then what?"
Baker looked ahead for a long time: "Nothing happened."
Liang Xi smiled and said, "Go ahead." Liang Xi believed that the raid on Baker's residence was just a random check, and the waste of manpower just happened to show that Isa valued Baker.
Baker said helplessly, "Then we had a tactical assessment and I got a low score. The problem is that our anti-powder team usually operates in small groups, with at least two people, and one person is not allowed to perform risky tasks. Blade is very abnormal and requires one person to complete the task. I neglected a little bit of details during the assessment, and finally failed."
Liang Xi asked curiously: "A little?"
Baker said unhappily: "Didn't I mention five points?" Although he knew that it was his fault that he didn't meet the standard, Baker was very unhappy with Blade's cold and condescending attitude.
A month ago, Liang Xi would have thought Baker was right. After experiencing the terrorist attack, Liang Xi believed that Blade's high standards for team members were necessary. Liang Xi consoled him, "You have your own unique characteristics. You have strong combat effectiveness, rich combat experience, and are good at indoor close combat."
Baker sighed deeply. "What you said are only the basic requirements of the Blades. In addition to the combat capability you mentioned, each of them has their own specialties. I have to admit that the Blades are very strong. Their establishment is 15 people, but now there are only 10 people. It can be seen that their selection process for members is very strict."
Liang Xi disagreed: "Of course, it is possible to have a completely elite force, but if there are no personnel that you are satisfied with, you can retreat to the second place. I don't think it is a good thing for 15 people's workload to be completed by 10 people and 15 people's risks to be borne by 10 people."
Baker instead began to speak well of Isa: "No, no. Isa not only selects fighters, but also commanders. Every Blade has the ability to command an operation."
Liang Xi pondered for a while: "Isa's husband passed away a few years ago."
Baker didn't understand at first, but after he reacted, he hurriedly explained, his words slurring in his haste: "I didn't, I didn't, I didn't have that idea."
Liang Xi suddenly realized: "The one you like is Liu Zhen."
Baker laughed: "How is that possible? She is our brother."
Liang Xi spread his hands. Without comparison, there is no result. Once compared, Baker's inner thoughts were revealed. Although Baker understood this, he did not care. He smiled heartily: "Isa is a very good woman. She has no intention of starting a relationship. As a single person, I am not mentally prepared to get married and become someone's father."
