Although Duan Yun only points the computer programming skills to the intermediate level, this level is also very high, even above the average programmer.

After putting his hands on the keyboard and opening the programming software, Duan Yunyun's fingers flew like flying, and strings of codes appeared on the screen quickly.

Seeing this scene, Guo Haitao, who was standing behind Duan Yun, showed a look of surprise on his face.

Although he has been engaged in mathematical research for more than 40 years, Guo Haitao has officially come into contact with personal computers in the last ten years.

Again, Guo Haitao once stubbornly insisted on using mental arithmetic to complete his daily work, but as he got older, the heavy mental arithmetic work made him a little overwhelmed, so he turned to using a microcomputer.

When Guo Haitao finally found that the microcomputer was of great help to his work, he had studied for a period of time without sleep and food, and Guo Haitao, a computer lecturer at the apprenticeship school, made rapid progress, and in only one year, his programming level has reached the level of a professional programmer, and he has become a computer master worthy of the name.

But at this time, after Guo Haitao saw Duan Yun's programming speed, he was immediately a little ashamed, because in his opinion, Duan Yun's programming technology was not inferior at all, even compared to the microcomputer teacher of Huaqing University, and it was more than a step faster than his own speed!

Guo Haitao had always felt that he was a genius in learning, but at this moment, he found that Duan Yun's talent was obviously far above him!

This shocked Guo Haitao at the same time, and his heart was also in ecstasy, which showed that he really didn't see the wrong person, and Duan Yun was even stronger than he thought before!

Moreover, if Duan Yun's computer level is high, Guo Haitao can also save Guo Haitao from spending time cultivating him in the future, and he can go directly to work.

There is no doubt that Guo Haitao just wants to pull Duan Yun into his research group, this is his real idea and purpose, of course, the premise must be Duan Yun himself.

It is the dream of a non-math student to enter the project team led by the highly respected Guo Haitao, after all, this is a promising job that can achieve both fame and fortune, but for Duan Yun, who is now a star and a net worth of hundreds of millions, it seems to be not very attractive.

"That's the app I used before. After Duan Yun finished typing the best character, he turned his head to Guo Haitao behind him and said, "Teacher Guo, are you right?"

"Wait a minute, I'll verify. After Guo Haitong finished speaking, he motioned for Duan Yun to leave, and after he sat down, he opened a document on the desktop and entered one of the data into the program that Duan Yun had programmed.

After Guo Haitao clicked the 'Calculate' button, there was an extra document on the desktop in an instant.

Guo Haitao clicked on it, and there was a lyric of "Jindalai".

"Not bad!" Guo Haitao nodded with satisfaction and said to Duan Yun, "How long have you learned programming?"

"A month or two. Duan Yun naturally wouldn't tell Guo Haitao that he had a super five good student system, so he casually dealt with it.

Guo Haitao showed surprise again when he heard this, but he didn't ask much.

If someone else told him that he could achieve such a high level of programming in only one or two months, Guo Haitao would definitely not believe it, but from Duan Yun's mouth, Guo Haitao would not have the slightest doubt.

Because in his subconscious, he already regarded Duan Yun as a 'super genius'.

"Wait a minute. Guo Haitao said, stood up, walked to the bookcase next to him and began to rummage.

After a while, Guo Haitao took out a thick foreign book from the top row of the bookshelf, and then took out two pages of paper sandwiched in the book.

This paper is printed with rows of binary numbers that look like they have no rules at all, densely packed with tens of thousands of characters!

"You look at this first. After Guo Haitao handed the two pieces of paper to Duan Yun, he said, "This is also a code text, you can take a look." ”

"Okay. After Duan Yun took the two pieces of paper, he immediately glanced at them.

For ordinary people, Guo Haitao's two pages of numbers are completely 'heavenly books', but in the eyes of mathematicians, they are a different landscape.

It's just that even Duan Yun, who is proficient in master mathematics, couldn't help frowning after seeing these two pages of passwords.

Obviously, this encrypted password is obviously much more complicated than the one Duan Yun came into contact with last time, and the difficulty is even higher.

For a while, Duan Yun took the code text and fell into deep thought.

Regarding Duan Yun's reaction, Guo Haitao was obviously expected.

Because although this cipher is also the French military cipher of the last century, it is five or six years later than the Soviet Union's encryption method that was changed from the German army's Engoma cipher, so it is more complex and advanced in algorithm.

And this cipher is a generation higher than the algorithm of the previous Soviet cipher, which is considered to be the third generation of the internationally recognized cipher, and even until now, in some countries in the Middle East and Africa, the improved algorithm of this encryption method is still used, which shows the complexity and security of this encryption method!

After more than twenty minutes, Duan Yun put down the code in his hand and began to program on the computer.

Soon, Duan Yun wrote out an encoding program and entered the encrypted file into it.

The moment you click on the arithmetic key, a document appears on the desktop.

But after Duan Yun opened this document, he found that there were still a bunch of indistinguishable characters and garbled characters inside, obviously Duan Yun's decoding method was incorrect.

"Take your time!" Seeing this scene, Guo Haitao behind him comforted Duan Yun, then got up and walked to the living room, and put a cup of tea next to Duan Yun's table.

Duan Yun was unaware of Guo Haitao's movements, and at this moment, he was already engrossed in putting his mind on the code.

Next, Duan Yunyou quickly came up with several algorithms, programmed them, and decoded them again.

But to Duan Yun's disappointment, his program never cracked the recognizable words or characters.

And Guo Haitao, who was standing behind Duan Yun, always stared at the programs that Duan Yun had made up, and a faint surprise flashed on his face from time to time.

Duan Yun's cracking method was like a wild idea, even Guo Haitao was able to keep up with Duan Yun's train of thought for a while.

Divergent thinking is very important for a practitioner of cryptography, and people with fixed thinking are obviously not suitable for this profession.

Minutes and seconds passed......

"It's time to eat!"

At this time, Yang Ying's joyful shout came from the kitchen.

"Eat first, eat first!" After hearing the shout, Guo Haitao patted Duan Yun on the shoulder and signaled him to pause the problem first.

Although he was a little unwilling, Duan Yun still got up and left the computer chair and followed Guo Haitao to the living room.
