Bit Mania [Hacking]

It was really unexpected that someone who had been separated for six years suddenly appeared in front of him. Zixin was overjoyed, and went up to hold the hand of the visitor: "Why are you here? How long have you been here?"

Xingchu glanced at the other person present, and replied with a half-smile: "I arrived half a year ago, and I found that this place is indeed the safest."

"Then do you know where my dad is?"

Xingchu shook his head, then nodded again: "When I got here, I was no longer there. Judging from the ashes on the furniture, it may have been a year or two at least... But," he said apologetically at this point, "I found Luo After Uncle disappeared, there was no way to contact you, and I had no choice but to pick the door lock. I didn't search for anything in the house, but found this in a conspicuous place."

As he spoke, he took out a letter from his pocket and wanted to hand it to Zixin: "It looks like Uncle Luo left it for you..."

Just as Zixin was about to reach out to pick it up, someone stopped him one step faster. It was Zheng Xiu.

"What Qi Xingchu said is just one-sided words," Zheng Xiu said coldly, "Who knows if he deliberately led your thoughts away?"

Zixin was taken aback for a moment, and laughed: "Zheng Xiu, it's better to be cautious, but Brother Xingchu won't hurt me." He patted Zheng's shoulder with one hand, and took the letter with the other: "Let me see it first. Let’s talk about what’s written on it…”

He had already guessed that the two people in front of him should know each other when he first met Zheng Xiu, but the atmosphere of meeting today was a bit weird. No one would have expected the entanglement of these two dear friends in rebirth, past life, and present life. The twists and turns in it would be a big book if written down, and they are all stern characters How could Zixin know that if he hadn't been present now, the two of them would have already had their old and new hatred torn apart.

Therefore, he really couldn't think too much. He unfolded the letter and looked at it. Seeing this situation, the other two knew that the business was important, so they didn't say anything more. What words, but a bunch of seemingly disorganized symbols.

"After several months of analysis, I can confirm that this letter should be a set of passwords," Xing Chu said aside: "But I have never heard of these symbols before, how about you?"

Zheng Xiu, who is a cryptographer, frowned and shook his head unwillingly.

But Zixin stared at the symbols on the paper with a pensive expression on his face, before saying after a long while: "These... I should have seen them before."

"Where?"

"The puzzle game I played with my dad when I was young."

As Zixin said, she went to the table and blew a little to blow off the dust on the table, put the letter paper on, then turned around and went into her room to get a pen and paper, and just stood there and began to crack it bit by bit, maybe It's been a long time since the age passed, and Zixin explained it very slowly, stopping to recall from time to time, and then wrote down a few more strokes after thinking about it.

Zheng Xiu and Xingchu watched him operate from the sidelines, and the expressions on their faces became more and more dignified. Even though the water and fire were incompatible, the two still couldn't help but look at each other, and they both saw surprise on the other's face.

RC4, RSA algorithm, hash function... This thin piece of letter paper actually covers the twelve most classic encryption algorithms in the world today!In fact, it is not difficult to understand these encryption methods, but most general files are encrypted by one or several of them in a targeted manner. Therefore, after trying a few times, decryptors often think that they cannot solve the problem. The solution is wrong. I never thought of adding these algorithms one by one in a specific order. If I don’t understand it, I can’t see a clear answer at the end.

This letter is... almost like a textbook listing all the algorithms—no wonder, no wonder!If Zixin was really played with by his father when he was a child, it would explain his magical thinking talent when he grew up.

Even so, this encryption is not difficult for Xingchu and Zheng Xiu. The real reason why both of them are helpless is the symbols used above.Zixin and his father’s exclusive secret language is easy for Zixin to recognize, it’s just that the 26 English letters have changed shapes and are completely different, but to outsiders who don’t know it, it looks like a new language, no wonder Luo Hui left this letter in a conspicuous place in the house, not afraid of being found and taken away.

Now it seems that Zixin's father, Luo Hui, is definitely not an ordinary character. Who is he?

While the two were wondering and uncertain, Zixin had been counting intermittently for three or four hours, and finally put down his pen, and straightened his waist, which had been sore from staying in one posture for a long time.

"Papa's whereabouts are known," he said.

Xiao Xin:

When you read this letter, I must no longer be by your side.Don't be afraid, as long as you remember what I taught you in the past, we will still meet.Dad should be very safe now. The reason why he left without saying goodbye... is because of his reasons. He has hidden many things from you. It's not that he doesn't want to tell you, but it's just that the time has not come. Both you and me are in danger.Now, come to me, leave a letter too hastily to say, let me tell you all in person.Don't forget to hide yourself and don't be followed, otherwise you may die.I am here……

Huaguo, city C on the southwestern border.

The scorching sun and the continuous mountains are the symbols here. A road runs through the city and even the suburbs, leading to the border checkpoint with the Monkey Country. The small triangular flags connected with ropes depict the successive mountain lines, as a symbol of the relationship with Indochina. In the area bordering the three countries, there is a border military area. You can often see groups of soldiers with guns on the road, and military vehicles passing by. Huangsha——This is the only trade route between China and the Monkey Kingdom. Although the tea and horse trade is not well-known, its value is as important as the Silk Road.

The railway is quite old, and the green leather train stopped at the platform. The three of them got off the train, and Zixin didn't mention it. The partners were a little dazed for a while, standing there to identify the direction.

"...Dianxi Village, City C, are you sure?"

"The translation is like this..."

"Is it so remote that it's not even marked on the map..."

"You can ask the locals..."

"...Zheng Xiu, don't make trouble." The crowd on the platform was crowded, and the scene was very chaotic. Zixin suddenly felt an itchy waist, thinking it was Zheng Xiu's trouble, and used his usual backhand to take off the claw and throw it away. However, as soon as I held it in my hand, I found that the hand felt a bit wrong. Looking down, the hand was dark, rough, and sensual, with dirt that would never be seen in Zheng Xiu's hand.

What's more, Zixin's eyes widened for a moment - now this hand was holding the wallet that he had put in his pocket - it was a pickpocket!

The pickpocket reacted quickly, and after a moment of surprise, he broke away from Zi Xin with his eyebrows raised, and ran away.

"Me?..." Just as Zheng Xiu was about to speak, there was still something he didn't understand when he saw this scene. Qi Xingchu who was on the side also noticed the situation at this time, and immediately turned around and chased after him.

After all, the two were young, strong and good young men who exercised every day. Without any suspense, the pickpocket was captured after only running about 30 meters away. Just as they brought back their wallets, they heard footsteps coming from all around them. They looked up, my good guy, in the blink of an eye, they were already surrounded by seven or eight people.

This group of people was obviously in the same group as the pickpocket, and they were not polite when they came up. They raised their hands to greet the two of them. The fist greeted his eye sockets. He hugged his head and squatted down in fright, which actually made him get out of the way. But how could the opponent have nothing to do with such a rookie? After the punch missed, he raised his foot and kicked , Zixin only felt an unnatural cool wind blowing over his head, he looked through his fingers, and just saw Xingchu raised his leg, tripping the kicker's foot that was supporting the ground to the ground At the same time, Zheng Xiu also knocked down one neatly.

The scene completely turned into a fight between two gangs of men. It was extremely chaotic for a while, and the people on the platform automatically gave way to a circle. Zixin was shocked and frightened when he thought that things would turn out like this, and hid in embarrassment at the beginning of the line In the back, after he regained his composure for a while, his eyes turned and he lay down on the ground and picked up a brick. Just as he was about to seize the opportunity to shoot a cold arrow at someone, his hands were suddenly empty. Zheng Xiu weighed the brick in his hand. He said thank you.

Zixin: "..."

Xingchu took the time to say: "Stand between us, don't stick your head out."

The situation in front of me is obviously impossible for everyone to stop and reason. There are two and a half people here, facing seven or eight young people. It sounds difficult, but the two people on my side are not people with ordinary experience. It is not difficult for a person who has attacked countless policemen in his previous life to deal with ordinary gangsters with less to win more.However, you can take the opportunity to deal with Qi Xingchu... The border area is already chaotic, and it is common for local snakes to kill people...

Zheng Xiu thought to himself, his eyes darkened, and he parted a ray of attention to glance at someone, but happened to see Xingchu's face change slightly after receiving someone's punch, and Luo Zixin pulled up behind him and fled.

Zheng Rabbit's eyes widened in disbelief, this, this person ran away with Zixin? !

In the past, it was always his yin relative Xingchu, but today he, Zheng Xiu, was turned on his head by the other party? !

"Zheng Xiu, run!" The man didn't find time to shout to him until he got into the crowd with Zixin.

"...You!" Seeing more people approaching him, Zheng Xiu gritted his teeth and knocked over the nearest person. Fortunately, Zixin had already been taken away by someone named Qi, and now he could not act alone. Conveniently, he directly stepped on the man's belly, followed by sneaking into the crowd, and the gangsters wanted to chase after him, so he threw the brick back with his backhand, and the other party all backed away, and there was no one left.

The three ran across a few streets in a panic, and after making sure that no one was chasing them, they breathed a sigh of relief. They were all out of breath, and Zheng Xiu even held his breath in his stomach, and stood there without saying a word.

At this time, Xingchu spoke, unexpectedly, instead of Zheng Xiu, he brought up the topic himself: "Do you know why I was in such a hurry to take you away?"

"……how?"

"Among the group of people just now, there are a few tricks... like military boxing."

"Military boxing?" Zixin frowned.

"Well, if you really want to talk about soldiers, I'm afraid it's too weak... Anyway, it's a bit strange, so I think it's better not to cause unnecessary trouble." Xingchu said: "The most urgent thing is to find uncle."
