The two technicians could see clearly behind them, Zhang Yi seemed to have chosen at random, and the modified coding was also very arbitrary. However, after the modified executable file replaces the original file, it is directly the official version of the software that has been registered.

I am also a technician, and I have also dabbled in some cracking techniques, so I know the difficulty of this.

First of all, the choice of which sixteen codes are the first pass.

This level is stuck with a lot of people;

Secondly, what exactly should the modified code be changed to is another pass, and under this pass, corpses are everywhere.

If you know how to code, you don't necessarily have to crack software, but if you can crack software, you must first be proficient in programming.

Cracking software is an extremely difficult challenge in the world at present.

What's more, in China in the 90s, there were very few people who could program, let alone crack software.

The two technicians, looking at the young, that is, seventeen or eighteen-year-old Zhang Yi, couldn't imagine at what age he started learning programming, and how he was proficient in decompilation and cracking.

Zhang Yi had no time to pay attention to the two technicians behind him. Even if he was asked why he chose to modify this code, he couldn't tell clearly, as if it had already been stored in his mind, and what he did was just to reproduce the cracking process in his mind in reality.

At this time, in my mind, the familiar, mechanical voice sounded again: "Crack the compression software RAR, the smart hard disk is open by 3%, and then, a huge flow of information is crazy in my mind." ”

The two technicians standing next to him felt that Zhang Yi, who was sitting in front of the computer, shook his shoulders slightly, and the keyboard he was typing suddenly stopped, and for a long time, they sat quietly without the slightest movement.

The two looked at each other, a little strange, patted Zhang Yi on the shoulder, and asked suspiciously, "Boss, what's wrong with you?"

Zhang Yi forcibly suppressed the shock in his heart, and turned around and responded: "It's okay!"

He saw from the flood of information that the vast majority of the information was programming knowledge, and the code used in the programming language was C. There are also quite a few ways to crack the software and the compilation process.

What is this smart hard drive, why did it appear in his mind out of thin air, he can't figure it out, but it's impossible to discuss this secret with others, what if others know about it and take him to the laboratory as a guinea pig to dissect it?

However, no matter what, the C language that I learned in my previous life was half-understood, and this time I feel that I have mastered it thoroughly.

You know, almost all high-level programming languages in the future will be developed based on the C language. The Unix system used for the server, the open source Linux system, the windows system, and the popular Apple system, the kernel part of these operating systems are all developed in the C language.

It can be said that the C language is the foundation of modern computers.

The smart terminals and smart home devices used in the future Internet of Things, and the embedded chips used in them are basically all developed by the C language.

With only one RAR compression software, it's still a bit thin.

Continue to choose commonly used software to crack.

guarding a mountain of gold, but not being able to get a glimpse of the true face of Lushan, makes his heart itch.

He had to crack enough software to see how much software knowledge that hard drive could instill in him.

In terms of speed, the number of cracked software is increasing at an alarming rate, the proportion of the openness of intelligent hard disks in the mind is also increasing, and more and more computer software and hardware knowledge is constantly accumulating in the mind.

At 10%, Zhang Yi stopped cracking, not because he couldn't crack it, but because there were too many things stuffed in his head in a short period of time, and he felt like he was about to explode.

After resting for a while, I stabilized my spirit.

He took out a blank CD, made a simple windows PE system, gave it the prank name of "micro-hardware software", and stuffed all the cracked software into it.

Then, add many layers of protective shell to the operating system of the disc to prevent people from decompiling and stealing the fruits of his labor.

Hunting geese all day long, if you are pecked blind by geese again, it is better to find a piece of tofu and die.

Finally, a dealer directory was added: the addresses and telephone numbers of several dealers given by Mr. Ding were added.

While increasing sales, by the way, advertise your own dealers to increase their visibility.

After doing all this, Zhang Yi handed the CD to the two technicians and asked them to take it to other computers to test.

The two of them picked up the disc excitedly, and the impatient look made people laugh.

Test Results: All cracked software works fine.

I took out the disc and tried to crack it on another computer next to me.

However, the results were astonishing.

When cracking, a prompt pops up on the computer screen: "This disc has been used by the user, if you want to continue cracking the software, please buy a new disc from the dealer, thank you for your cooperation!"

Then a row of dealer directories pops up.

The two technicians stared wide-eyed, they didn't understand how this technology to limit transmission was realized.

Zhang Yi smiled and explained: "When you use the disc for the first time, you will read the computer's motherboard, hard disk, central processing unit and other information, and when you read the disc again, this information will be compared, and if it is the same, it will agree to run, and if it is different, it will stop running." ”

It dawned on the two technicians that this was the first time they had heard of this principle, and it seemed quite simple, but how did it come about? They had no clue.

Ignoring the two meditative technicians, he stood up, rubbed his swollen head, and moved his waist.

Looking up, the sky of Yuezhou, which was still blue, breathed a long sigh of relief.

A small software cracking disc has built a high threshold for the software disc industry, which has no technical content and threshold.

Zhang Yi, who used to just want to make a lot of hot money in a short period of time, flashed away, and now his mind has changed a little.

The experience of his previous life told him that the early stage of computer software CDs was to grab money, and the profits were scary.

Even in the later stages, the profits were good, and this craze lasted for almost a decade.

Finally, because of the increasing popularity of the Internet, the increasing network bandwidth, the faster and faster download speeds, and the rampant cracking websites and forums of various cracks, the computer software disc industry has been forced to slowly disappear.

And I am very familiar with the development of this industry.

What's even more commendable is that the current self has a software level that I didn't dare to imagine in my previous life, coupled with the software cracking ability brought by the anti-sky smart hard disk in my mind, if I don't manage it well, God will not forgive myself.
