It turned out that Shi Xinxin and Zhang Zhuming had already secretly fallen in love back then.

However, Shi Xinxin still gave Zhang Zhuming a hurdle.

That was to crack her code.

Zhang Zhuming relied on his understanding of Shi Xinxin and his own ingenuity to crack the password within half a month.

And finally, four words: I love you too.

"I definitely won't ask Professor Zhang about this kind of thing, it's a matter for the two of them."

Gao Zhiwei said: "There are a few other researchers with me who know about this. But as far as I know, they knew the results and didn't ask for a solution. ”

"You know us researchers, too."

He smiled and continued: "If you don't make it yourself, it's always interesting to copy it from someone else. ”

Li Qiming nodded half-understanding and half-understanding.

For him, as long as he can copy it, he will definitely not be stingy with his morality.

After all, news is not only new, but also fast!

"Thank you for your hard work, Professor Gao."

Li Qiming smiled and habitually took out some gifts from behind him and said: "This little shortbread is not a tribute......

"It doesn't have to be this way, I'm just doing a favor, and I haven't helped yet."

After Gao Zhiwei politely refused, he left under the pretext that he was busy doing research.

Li Qiming checked the information and knew that Gao Zhiwei liked small shortbread before he specially prepared it.

But I didn't expect that all the people who engaged in research were so brainless?

At the same time, Jiang Bai waited until everyone woke up and told what he had discovered.

They all gathered in the study on the first floor.

"There may be a possibility, or it may be wrong."

Du Yiheng said: "I'm not sure, this password is beyond my understanding. ”

"How do you know if you don't try?"

He Dazhuang said: "Try all the possibilities!" Maybe we'll be able to figure it out by mistake. ”

"It's impossible to mistake passwords."

Du Yiheng retorted: "The multi-encryption password is created to prevent accidental cracking. Unless you have the computing power of a computer, the possibility of cracking by mistake is almost zero. ”

"Or do you want to look for other hints first?"

Yan Xiyue thought about it and said, "Since there are hints in the villa, there may be other encrypted hints. ”

Du Yiheng nodded in praise.

Instead of fooling around, look for hints.

Since there are signs of this field shape everywhere, this villa must have hidden another hint.

"If I had to give a hint, I think the most likely one is in this room."

Jiang Bai said: "We have worked hard to crack the three stone gates, all the way up. The finish line can't be without any additional rewards. ”

After all, he hadn't searched the study very closely.

The first reaction was attracted by the shape of the bookshelf, and the second reaction was the hollow wall.

Other details may not be noticed.

Following Jiang Bai's train of thought, everyone began to look for it.

After some searching, they found Shi Xinxin's diary.

It is different from the mentality of modern people who "serious people write diaries".

At that time, it was quite popular for people to keep diaries, and even wrote diaries in order to show their "cultural literacy".

Of course, in the era when the Internet is not particularly developed, there will also be some high-level intellectuals who use diaries to vent their emotions or bury their little secrets.

For example, Shi Xinxin.

The back of the diary is full of careful thoughts about Zhang Zhuming.

Full of love girl taste.

Looking at this diary, it is a little old, and it is estimated that it was written in the early years.

Compared to the careful thinking at the back of the diary, the earlier part is very interesting.

This Tianzigzag encryption method is actually the first in history!

Several entries in the diary are illustrated.

At that time, she was doing a study of the ancient southwestern secession forces.

It is said that during the war, a spy appeared in a country called Yalan.

When passing on military information and some secret letters, it will always leak out.

Therefore, the army proposed a Tianzi-shaped encryption method to the emperor.

The information of the letter will be encrypted in the shape of a Tian character and turned into one incomprehensible sentence after another.

But in the hands of the generals, they can quickly scratch out unimportant words with a brush, or even read them directly.

As a result, spies can no longer transmit information to enemy countries.

Subsequently, the spy who was trying to find a way to crack it was also caught.

"It turns out that this thing still has a historical basis."

Everyone suddenly realized.

Du Yiheng thought about it and said: "But if you don't count the second half, there are too few things that can be transmitted." ”

"I'd better look for it again."

Jiang Bai said: "In the end, this only proves the secrecy of the Tianzig-shaped method. ”

He felt that as a rigorous professor, Shi Xinxin should not repeat one thing like this.

"Look!"

Yan Xiyue was originally curious about Shi Xinxin and her husband's past.

Unexpectedly, in the last two or three pages of the diary, something different was recorded.

"She used to give her husband a password like that?"

Du Yiheng was a little surprised to see the text on it.

The first page of the last two or three pages is the original text, and she wants to do a password test Zhang Zhuming.

The exact words are that I love you too.

Then the second page is about her conversion into numbers through the pinyin of the nine keys of her mobile phone.

However, the third page only explains that in case Zhang Zhuming can't solve it, he will tell him these secretly.

"The original text to pinyin, turn nine keys."

Jiang Bai said: "This should be a hint. ”

"But it's not the equation for solving X."

Du Yiheng said and shook his head, "Without confirming how many times she still encrypts, there is no way to push back." ”

The premise is that the password given to Zhang Zhuming is the same as this set of passwords.

"The original text X first became pinyin, and then turned to nine keys, after what changed back to text, and finally encrypted with Tian Zi method?"

Yan Xiyue said while thinking.

"Is there any way for the Nine Keys to turn into words?"

Jiang Bai asked: "It shouldn't be pinyin again, otherwise it will be homophonic at most, and it can't be such an unreadable sentence." ”

"Then there will be more changes."

Du Yiheng said: "It's still the same sentence, no hint is equivalent to looking for a needle in a haystack." ”

He then gave several examples.

Numbers to ASCII code and then letters to pinyin text.

Numbers are used in binary, and then become Morse code, and then converted to letters and words.

……

"Wait, all these methods you mentioned are to convert letters and then turn them into words, right?"

Jiang Bai caught the clue, "In other words, these unreadable words must first be turned into letters before they can be decrypted in the next step!" ”

"Remember to find a way to get your hands on it today!"

Li Qiming, who was in front of the display screen, saw Jiang Bai's exquisite reasoning.

He was a little scared.

If you lose the bet, you will not only have to kowtow in a low voice, but also make these nameless and garbage college students make headlines.

Then your career is over!

He immediately contacted the person who had infiltrated Shi Xinxin's villa and tried to find a way to steal the diary.

At the same time, everyone followed Jiang Bai's train of thought and began to crack the third diary.

"Not much."

Jiang Bai said: "This is a character deducted according to the slate Ueda calligraphy. ”

"JingFaJiuBuDuo, these should be the first steps forward to decryption."

Du Yiheng said: "I'll try it with ASCII code first. ”
