Zhongguancun, electronic supporting market.

The Zhao brothers came to a counter with "software service" written on it, Zhao Xingwang coughed lightly, and the little boss who was writing code in front of the computer at the counter looked up at them and asked lazily, "What do you want to buy?"

"I want to ask, can you do software unlocking here?" Zhao Xingwang asked.

"What software?" the little boss was obviously in spirit, he stood up and asked across the counter, "Is it domestic software or foreign software?"

"It's domestic, a mapping software. Zhao Xingwang said.

"Domestic software is a bit cumbersome. The little boss frowned, "Foreign software is easy to crack, foreigners are very stupid, and there is basically no encryption method." Domestic software is much more troublesome, and those programmers are not very good at making serious software, and the encryption algorithms are more complex than the other, which is very difficult to solve. ”

Zhao Xinggen said coldly: "You just say if you can solve it, money is not a problem." ”

"Haha, the boss laughed, that's what we do, how can we not solve it. The little boss immediately smiled on his face, and he beckoned: "Come on, come to my counter to talk, I have Coke." ”

The Zhao brothers entered the counter, and the little boss found two plastic stools for them to sit down with, and sure enough, they both took a Coke, and then asked, "What software do you want to solve?"

"Have you ever heard of Huaxia woodcarving design software?" asked Zhao Xingwang.

As soon as these words came out, the little boss was stunned for a moment, and then smiled bitterly: "No, this software is so popular now?"

"What do you mean?" Zhao Xinggen asked sensitively.

The little boss pointed out with his hand and said, "In this market, there are at least five or six companies that have taken over the job of breaking this software." It's been more than a week, and I haven't heard of any broken houses. When I was out smoking with a few buddies, I heard them say that this software is so immoral that it uses two dongles to encrypt in a loop, and no one knows how its algorithm works. ”

"Two dongles?" Zhao Xingwang grinned, it seems that Linyi Machine has really invested money in order to prevent piracy.

The control program of the long tassel wood carving machine actually has two parts. One part is to use wood carving design software to create a digital file that conforms to specific drafting specifications, and this part is done on a computer. The second part is to read the digital file, and then convert it into the control signal of the milling head according to a certain algorithm, which is completed in the CNC module of the machine tool.

These two parts, as long as one part can be cracked, the algorithm of the other part can be deduced, and the entire wood carving control program will be cracked. The program of that part of the CNC module is directly written on the rewritable chip, and no one can copy it, so Zhao Xingwang pinned his hopes on the drawing software, hoping to crack the coding rules of the drawing software to speculate on the program in the CNC module.

has the same idea as Zhao Xingwang, but there are more than one or two. Longhu Machinery Factory is not the only one who likes the market of wood carving machine. Long before the Zhao brothers came to the capital, other machinery companies had already sent people to Zhongguancun to find a way to crack the software.

In this era, there are various software encryption techniques, including serial number encryption on programs, special methods encryption on floppy disks, and hardware encryption methods. The last method is to write the decryption program on a rewritable chip, and then connect the chip to the card slot of the motherboard, or connect it through a serial or parallel port, which is called a dongle.

The method of using hardware encryption is more expensive and more troublesome to use, but the advantage is that it has good confidentiality and is not easy to crack. Some experts can analyze the encryption principle by monitoring the communication between the dongle and the host, and then use software to simulate the encryption process to achieve decryption.

When Tang Zifeng arranged for the new Jingwei company to develop wood carving software, he took into account the issue of confidentiality. As soon as he told Zhao Yuntao and Liu Xiaohan his thoughts, the two immediately proposed to use dongles to encrypt, and boasted that when they were practicing stalls in Yibin Building, they also helped others unlock dongles and knew this thing very well.

Because they knew that dongles were not absolutely secret, Zhao and Liu decided to equip the software with two dongles, and the two encryption chips were encrypted in a loop, so that the crackers were at a loss.

The drawing software that Linyi resold to the woodcarving shop, each set of software carries such two dongles. When installing the software, you must plug the dongle into the computer for the software to run smoothly. Without these two dongles, the software would not work. Some people buy the software and try to copy it to other computers, but it doesn't work.

The graphic files generated by Huaxia woodcarving CAD are ultimately encrypted by the dongle, and the encryption is formed into a file composed entirely of garbled characters, and no one can identify the definition of various graphics in the file, so there is no way to know how the control program of the woodcarving machine works.

"You said that five or six stores have taken over the job of cracking Huaxia software, how are they progressing now?" Zhao Xinggen asked.

The little boss shook his head: "It's not going well, the boss of the house next door to me is a computer master, and he also works in some research institute, and the level is very high." In the past two days, I have seen that half of his hair has fallen out, but I haven't heard of any progress. ”

"So, can you untie it?" Zhao Xinggen asked again.

The little boss said: "I can only say that I will try, but I dare not guarantee it." However, I said ugly that in the front, you have to pay a part of the money first, and then if you untie it, you pay another part, and if you can't untie it, I won't return the money in front of you. ”

"You haven't untied it, why are you taking the money?" Zhao Xinggen said angrily.

The little boss smiled: "Boss, this kind of thing is a gamble on luck, and no one dares to say that they can unravel the program." If you can't untie it, you won't give money, then who will pay attention to doing this kind of thing? We all have this rule here, first negotiate the price, and then pay 30 percent, as a labor fee, untie it and can't untie it, and the 30 percent will not be refunded. If it is untied, then collect the next seventy. If you don't believe me, you can go to another stall and ask. ”

"There are such rules?" Zhao Xinggen didn't believe it, but looking at the calm face of the little boss, he had to believe it. This kind of thing can be verified by casually going out and asking, and the little boss probably won't lie to his face.

"How much does it cost to solve this program?" asked Zhao Xingwang.

The little boss held out a slap in the face. Zhao Xingwang was stunned: "500?"

The little boss was happy: "Boss, can I ask you to do 500?"

"You mean 5000?"

"That's right, pay 1500 upfront, and if it does, pay 3500. ”

"This ......" Zhao Xingwang turned his head to look at his brother, not sure if he wanted to spend this unjust money. The conditions that the little boss said are really a bit risky, in case he collects money and doesn't do anything, what can he do?

Zhao Xinggen gritted his teeth and said categorically: "Give it to him!"

Zhao Xingwang paid 1,500 yuan to the little boss, and gave the little boss a set of wood carving and drawing software bought from Linyi for him to use when he cracked it. The wood carving machine tool and drawing software sold by the machine are sold separately, this is because some wood carving shops only buy one machine tool, but they want to buy two sets of software, so that two people can design at the same time, of course, there are also wood carving shops that require to buy two machine tools, but only need one set of software.

If the Zhao brothers want to crack the mapping software, of course, they must have a sample, and this set of software was bought separately from Linyi by them. There are two dongles in the software box, but Zhao Xingwang doesn't know their functions.

After paying the money, taking the receipt issued by the small boss and a simple agreement, the Zhao brothers turned around and wanted to leave, and they heard the siren outside the market, and then, four policemen entered the supporting market violently, and went straight to a counter, led by a policeman who asked sharply to the two young people in the counter:

"You two, aren't you Deng Lei and Ling Jianping?"

"I'm Deng Lei, I'm Ling Jianping. A young man asked tremblingly.

At this time, all the surrounding merchants turned their eyes to this side, and a few bold ones simply came forward to see what was going on.

"Have you cracked this software?"

The policeman pulled out a box and asked the young man named Deng Lei.

The Zhao brothers stood not far away and watched, and when they looked at the box, both of them sighed in their hearts: Isn't it just such a box that they just handed over to the little boss? This is clearly a set of Chinese wood carving and mapping software.

There are many merchants who have the same reaction as the Zhao brothers. Someone quickly hid an identical software box on the counter, and pricked up their ears to listen for the action.

"I ...... We haven't seen this ......" Deng Lei's voice trembled, making people hear the meaning of "there is no silver here".

"The two of you are suspected of infringing software intellectual property rights, and the amount involved is particularly significant, and we have received a report, please go back with us to cooperate with the investigation. The policeman didn't care about Dunley's excuses, and he loudly announced the two men's crimes. Then, several policemen who came with him went straight to the counter, went in and dragged the two out, and quickly handcuffed them.

When the police took Deng Lei and Ling Jianping out of the supporting market, the leading policeman turned around, held up the software box in his hand, and said loudly:

"Ladies and gentlemen, we have received reports from the masses that there are no less than 10 merchants in this market who are trying to crack Huaxia CAD software. New Jingwei has reported the case to the police. Just now, these two have handed over the software they cracked to the illegal manufacturer, and the illegal manufacturer produced the infringing wood carving machine tool.

At present, the person in charge of the manufacturer involved in the case has been arrested, and he confessed that it was Deng Lei and Ling Jianping in the market who helped him crack the software. Here, I warn all merchants who try to crack this software not to defy the law, otherwise the law will be ruthless!"
