Rebirth of Fortune Soars

Qin Feng left.

The three of them stay here, you look at me, I look at you, and then look at the resplendent and resplendent houses around, it's really like a dream.

You know, in China, their accommodation environment is not bad.

However, that is only in comparison with ordinary people.

Basically, it means living in a building with two bedrooms and one living room, which is relatively spacious and bright.

At that time, they already felt very good.

But, come here, look at this manor villa, a bathroom is almost as big as their entire room.

Thinking about it, I feel heartbroken.

The house I used to be proud of is now only the size of a bathroom, and it is not as luxurious as others.

Of course, they were quite moved by how much they valued Qin Feng.

Now that they live in such a luxurious manor villa, if they don't value them, then it certainly isn't.

Otherwise, who would waste this money.

And all kinds of training facilities are complete.

This is comparable to the army.

Moreover, there are many more guns than troops.

"Okay, everyone, let's find a room to rest." The man with the gun scar grinned, "Since there are three of us, there must be a priority. So, we will have a game later to decide who is the boss!"

The other two had different expressions, but they all nodded in agreement in the end.

At this moment, after Qin Feng left here, he returned to his car.

Although, the manor villa also moved Qin Feng's heart.

Moreover, Qin Feng doesn't need to stay in school at all now. You can also live in a manor house.

However, that place is not safe.

For Qin Feng, this is the case.

that place,

Too spacious and no privacy at all.

Of course, the privacy in Qin Feng's mouth is different from the privacy in the eyes of ordinary people.

The place is too big, once someone invades, you don't know it at all.

Although, Qin Feng has no secrets.

But once the secrets he possessed were discovered, it would be a catastrophe.

At that time, I am afraid that the world will not tolerate it.

Therefore, Qin Feng has to be careful. And this RV is undoubtedly the safest place.

Of course, it's not really safe either.

If the other party really wants to rush in, while he is not around, the things in the computer may not be guaranteed to be preserved.

For example, the other party directly comes up and removes the hard disk, and then makes a copy.

The whole hard disk data copy, so, even if the data is accidentally damaged, it doesn't matter much. The other party, you can try slowly.

If it is broken, make another copy.

Therefore, I have to figure out how to lock the data on this hard disk to avoid being copied.

Qin Feng originally wanted to talk to Boss Ming about this incident on the phone.

Boss Ming also explained it before, if there is a result, please tell him.

Although Boss Ming can't change anything, he can make some preparations.

However, Qin Feng suddenly thought of this, and put aside the idea of ​​talking to Boss Ming.

For Qin Feng, on the whole, he is still an IT man. In this regard, like other IT men, if they have any ideas, they must be put into action.

It won't do if it doesn't solve the problem.

So, this research, just one week.

For a whole week, apart from staying in the RV, Qin Feng went out to eat.

However, within a week, Qin Feng also had a result.

The hard disk can indeed be removed directly and then copied.

This data cannot be prevented from being copied.

This is a physical plug-in, and your software cannot defend against it. The system is not turned on, how do you defend?

Therefore, only the entire hard disk lock can be performed.

When the hard disk sector reads data, it is directly unlocked. It cannot be read without unlocking it.

In this way, logging in will indeed be very troublesome, and a password of at least 32 characters needs to be entered.

And it contains passwords including uppercase and lowercase, and various symbols.

Such a password can theoretically be cracked, but it requires countless attempts.

According to Qin Feng's estimation, with the current computing power of human computers, it would take at least a million years for a supercomputer to crack it.

Of course, if you graft computers around the world and crack them together, it will be very fast.

It may be cracked in less than a year.

However, the problem is that you cannot graft.

If you crack it, Qin Feng has set a limit, that is, if you try 10 times and still fail, all data will be automatically destroyed.

The reason for this is that the data is too long.

32 bits, but also includes uppercase and lowercase, and special symbols. This made Qin Feng very stressed.

If you are not careful, you may make a mistake. Therefore, Qin Feng gave himself 10 chances to make mistakes.

It sounds like 10 times is a lot of chances to make mistakes.

But for trying to crack poorly, after 10 times, it will be automatically destroyed, so what should I do?

Of course, Qin Feng also assumed that the FBI cracked it. If it is cracked to the limit, then a software can be realized and grafted. At the same time, a large number of computers are cracking together.

But that requires a medium, the hard drive.

You must copy enough hard disks at the same time, and then perform simultaneous cracking, and, after the software is planned, password cracking groups can be performed.

In that way, it is possible to perform group cracking.

However, this also has a premise, that is, you have to get so many hard drives out.

As far as Qin Feng estimates, if he wants to crack it within a year, let alone hundreds of millions of hard drives.

Of course, this may not be enough.

Because, a hard disk can only be cracked 10 times.

After 10 times, the data is automatically destroyed.

Of course, to destroy the program, it is impossible to physically erase all the data at once, and it needs to be erased multiple times.

Then, a hard disk, according to Qin Feng's calculation, theoretically has three chances to try. That's 30 cracks.

100 million hard drives, that is not a small number.

And, it's not enough.

If you really want to crack it, well, you can get 10 billion yuan to see if it is enough.

After all, 32-bit passwords, passwords with uppercase and lowercase letters, plus special symbols, the combination has a total of...

Qin Feng made a rough calculation, the number is really astronomical.

26 uppercase letters, 26 lowercase letters, 10 numbers (0-9), a total of 62, plus those special symbols that can be used, a total of 68, then a 32-bit password has 68^32(62 32th power), about 2.272657884496751e to the 57th power, a super astronomical number! ! !

This is really a shocking number.

10 billion hard drives are not enough.

Therefore, Qin Feng was relieved at this moment.

However, the 32-bit password, including uppercase and lowercase, and special symbols, gave Qin Feng a bit of a headache.

Although, I have always had a good memory. However, such a long password is also possible to make mistakes.

In particular, human memory is very unreliable in some respects.

Hey, I have a headache, how do I write it down? Take notes? This is the most unreliable! Easy to be seen, and that's it.
