When I am reborn, I just want to be a top student

Tangdu Jiaotong University.

After receiving Xu Songyao’s call, Wang Donglai went straight back to Tangdu Jiaotong University.

When going upstairs to Xu Songyao's office, Wang Donglai suddenly noticed a black car with a special license plate.

Suddenly, Wang Donglai had a feeling.

The car might be coming for him.

With such a strange and nonsensical guess, Wang Donglai entered Xu Songyao's office.

After seeing the situation in the office, Wang Donglai’s first thought was that he had guessed right!

I only saw a few people in the office.

As the president of Tangdu Jiaotong University, he has the home advantage within the school. Logically, his momentum should be stronger.

But in fact, it is just the opposite!
Xu Songyao's momentum was actually at a disadvantage.

He only looked a little reserved and nervous as he faced the visitor.

"Hello, Academician Wang, I am Ding Liang from the Department of Mathematics at the National Defense University."

Ding Liang, wearing a military uniform, walked in front of Wang Donglai. He looked Wang Donglai up and down with sharp eyes, saluted, and introduced himself in a loud voice.

Yes.

This time, the person who appeared in front of Wang Donglai was a professor from the University of Science and Technology of China.

The special license plate that Wang Donglai saw downstairs before was also for this reason.

"Hello, I'm Wang Donglai!"

Wang Donglai nodded seriously and greeted him.

After greeting Ding Liang, Wang Donglai looked directly at Xu Songyao, a sincere smile appeared on his face, and said, "Principal Xu, is there anything you want me to do?"

Hearing Wang Donglai's question, Xu Songyao explained, "It's not that I want to ask you something, but Director Ding wants to ask you something..."

As soon as Xu Songyao said this, Ding Liang nodded and admitted it directly, saying, "Academician Wang, please forgive me for being so presumptuous. I should have contacted you directly, but some of the content and areas are sensitive, and my identity is even more obvious, so I have to publish this. I hope you can forgive me."

Wang Donglai's brows frowned slightly, then calmed down in an instant.

"Director Ding, is there anything you want to talk to me about?" Wang Donglai asked directly.

After hearing this question, Director Ding hesitated for a moment, then made a decision and said, "Academician Wang, I think the whole world knows about your achievements in mathematics. I wonder what you think of cryptography?"

"Oh, cryptography?"

"I think it's very interesting!"

Wang Donglai spoke directly about his thoughts without any embellishment.

After hearing what Wang Donglai said, Ding Liang remained calm and continued, "It's like this, Academician Wang, I have a code in my hand. If Academician Wang can crack it within the limited time, then I think Academician Wang is qualified to know the inside story."

"So, I wonder if Academician Wang is willing to give it a try?"

After Ding Liang said this, Wang Donglai immediately became interested.

"Okay, let's give it a try!"

Ding Liang was not surprised by Wang Donglai's choice. He directly took out a document from his briefcase and handed it to Wang Donglai.

Wang Donglai did not open it to check it out immediately, but asked a rather strange question.

"Director Ding, this document I'm reading, isn't it a confidential document? Do I have to sign a confidentiality agreement after reading it?"

Ding Liang was slightly stunned, and after he realized what was happening, he waved his hand and said, "Of course not!"

Wang Donglai nodded and said, "Okay, Director Ding's words make me feel relieved!"

After saying that, Wang Donglai directly opened the file and started to check it.

There wasn't a lot of stuff in the file. With Wang Donglai's ability, he only took a quick look at it for a while and then wrote down everything in it.

At the same time, Xu Songyao, regardless of his status as the principal, placed a pen and a stack of paper in front of Wang Donglai.

"Shhhhh..."

Wang Donglai took the paper and pen, and immediately ran the pen tip across the paper, outlining numbers one by one.

Seeing that Wang Donglai moved so quickly, it only took less than a few minutes.

Ding Liang's eyes showed a hint of expectation, but also a hint of doubt.

Does Wang Donglai really understand, or is he just pretending to understand?
Ding Liang was unable to make up his mind for a moment.

Time passed in such an atmosphere.

After Wang Donglai finished writing the last stroke on the paper, he looked up at Director Ding and said, "Director Ding, how do you think I can crack it?"

As he said this, he handed the password he had worked so hard to crack to Ding Liang.

Ding Liang did not hesitate and started checking it out immediately.

This sight brought a hint of surprise to Ding Liang's face.

Ding Liang really didn't expect that Wang Donglai would be so strong.

He knew very well how difficult the code in his hand was.

I don't know how much manpower and time were spent to crack this password.

Finally, it was cracked with the help of a supercomputer.

After making an evaluation of Wang Donglai's abilities in his mind, Ding Liang's mouth curled up slightly.

"Academician Wang, do you remember what I just said?"

"At present, there is a highly confidential project that requires cracking a code. The time is tight and the task is heavy, so I thought of Academician Wang, the youngest academician in China."

"To be honest, the higher-ups still think highly of Wang Donglai."

"And Academician Wang's performance just now also proves this point, so I am now officially representing..."

Before Ding Liang could fully explain his purpose, Wang Donglai stretched out his hand to signal Ding Liang to stop.

"Director Ding, I still say the same thing as before."

"Confidential projects, confidentiality agreements, I know all of this."

"How about Director Ding first explain what I need to do using a plan that does not involve violating confidentiality?"

Wang Donglai expressed his thoughts calmly and indifferently.

His expression seemed as if he was not worried at all that Ding Liang would get angry because of his interruption.

"it is good!"

After taking a deep look at Wang Donglai, Ding Liang agreed as expected.

After a moment of hesitation and thinking about it in his mind, Ding Liang asked, "Does Academician Wang know the MD5 encryption algorithm?"

Wang Donglai nodded and said, "Of course I know that. It is the information digest algorithm issued by the Bald Eagle Standards and Technology Bureau. It is a widely cited cryptographic algorithm."

"The MD5 message digest algorithm belongs to the category of hash algorithms. It runs on a message of any length and generates a 128-bit message digest."

"Its technical principle is not very complicated. First, data padding is performed on the message so that the length of the message is 512 modulo 448. Let the message length be X, which satisfies X mod 512 = 448. The data length that needs to be padded is calculated based on this formula."

"The second step is to add the message length. The length of the original message is filled in after the result of the first step. The storage length that can be used is 64 bits. If the message length is greater than 264, only the value of the lower 64 bits is used, that is, the message length is modulo 264. After this step is completed, the final message length is an integer multiple of 512." "The third step is data processing, which requires four constants: A=0X67452301, B=0X0EFCDAB89, C=0X98BADCFE, D=0X10325476, and four functions..."

After mentioning the MD5 cryptographic algorithm, Wang Donglai immediately started talking about it.

Seeing how familiar Wang Donglai was and the confidence he unconsciously revealed, Ding Liang became more and more expectant.

"What Academician Wang said is correct. Given the various characteristics of the MD5 cryptographic algorithm, it has a wide range of applications."

"And the project we are currently working on is trying to crack this code."

"To solve such a difficult problem, there is a prerequisite, which is also a necessary condition, that is, there needs to be a top mathematician as the core."

"And everyone may have their own ideas about this core."

"But in my eyes, Academician Wang is the best mathematician in China and even in the world."

Able to prove difficult mathematical problems in multiple research directions in a very short time.

This iron-clad academic achievement is here and no one can deny it.

"Academician Wang, this is all I can say."

"If you want to know more, I'm afraid you'll need to sign a confidentiality agreement."

Ding Liang kindly gave Wang Donglai a hint.

Hearing Ding Liang say this, Wang Donglai thought quickly for a while and soon came up with a rough guess.

If it were a different time, Wang Donglai might not be able to guess it.

But at this moment, no matter how slow Wang Donglai was, he knew that something big was about to break out in the South China Sea.

Although there is no evidence to confirm it, he just feels that his guess should be correct.

Thinking of this, Wang Donglai couldn't help but become excited.

At his level, there aren't many things that he finds challenging.

Cracking the code is, to a certain extent, also a challenge for him.

The greater the challenge, the more it can stimulate Wang Donglai's potential and fighting spirit.

Since he had already guessed it in his heart, Wang Donglai said, "To be honest with Director Ding, I have only read a few books on cryptography and do not have much real practical experience."

"Now that Director Ding has invited me, I can't help but give him face."

"I am willing to participate in cracking the MD5 password algorithm!"

Although he had guessed in advance that Wang Donglai would most likely not refuse and would definitely agree, when Wang Donglai really agreed, Ding Liang still felt relieved and became more comfortable.

"Academician Wang, I have two things I must make clear to you."

"This is related to the MD5 cryptographic algorithm system, and the higher-ups take it very seriously."

"So, we don't have much time left for research."

"At least you need to keep silent for half a month, or even a month without contacting the outside world. Can Academician Wang do this?"

"Also, anything you see in the project team must not be passed on to others. If it is illegal, you will be punished by law!"

"Academician Wang, there is no time to lose. How about we talk while we walk?"

Ding Liang suddenly persuaded Wang Donglai like this.

Wang Donglai naturally had no objection, so he nodded to show his agreement.

"Principal Xu, thank you very much for your cooperation. I have done what I needed to do, so I will leave now."

Ding Liang said goodbye to Xu Songyao with a smile.

Seeing the genius of his own school being taken away by Ding Liang like this, Xu Songyao felt a little strange at this moment.

However, these emotions were quickly suppressed.

"Director Ding, you are too polite. We would do the same thing no matter where we are."

Xu Songyao replied politely, somewhat stiffly.

soon.

Wang Donglai and Director Ding got into a car with a special license plate, left Tangdu Jiaotong University and headed for the Qinling Mountains.

On the road.

"Academician Wang, for the next period of time, we will be busy cracking the encryption algorithm at the base. In addition, due to its importance, we may not be able to communicate with the outside world for a long time."

"Academician Wang might as well make arrangements for the future development of Galaxy Technology to avoid any problems in the company's development."

"Also, you can tell your family members to avoid them worrying, as long as you don't mention any sensitive confidential information."

Ding Liang took the initiative to speak and said this to Wang Donglai.

"Thank you, Director Ding. I have my own arrangements for the company's affairs."

"I believe that even if I am not here, it will not affect the development of the company."

"As for my family, they also support my work. They don't ask me about certain things, and they know when to not mention them, so I can rest assured."

Wang Donglai said this with a smile.

Ding Liang nodded and said, "Academician Wang, at this point, I won't hide anything from you. I must make it clear what needs to be said."

"At the base, we just need to do our job well and crack the password of DM5 as soon as possible."

"Other things are not something we can control!"

"It's better to be cautious in what you say and do inside the base!"

Ding Liang's words were not very clear, but Wang Donglai could hear the real meaning behind them.

This further confirmed Wang Donglai's previous guess.

Know thyself, ever-victorious!
This is the purpose of the above to speed up the cracking of the DM5 algorithm password.

Wang Donglai nodded and didn't say much.

At this moment, he had already begun to think about what he could do in this matter.

My mind frantically recalled the various reports on the South China Sea incident in 2016 from my past life, as well as the various news circulating on the Internet that were difficult to distinguish between true and false.

As he unraveled the pieces of information one by one, a general picture soon formed in Wang Donglai's mind.

With this relatively clear cause and effect, Wang Donglai quickly made a decision.

It would be fine if I didn’t have the ability, but now that I have it, how can I be the same as in my previous life?

Thinking of this, Wang Donglai had already made a decision in his heart.

Thanks to Wa's existence, even though Wang Donglai does not show up in the company, he can still manage the entire company with high standards without making mistakes.

Even many people within Galaxy Technology did not know that Wang Donglai was no longer in the company, but had secretly gone to a confidential base to crack the password.

time flies.

Suddenly, a rather bizarre news report appeared internationally.

How could a small country sue a big country? (End of this chapter)
