Share how to compile passwords that are not easy to forget and are not easy to crack.

“11111” This number is easy to remember. If you need to set a password, use 11111, others do not know, you can not forget, you can consider.

However, if someone finds this password, people will never forget it. What should I do?

Double encryption can be used. Usually see the number 11111, it consists of 5 ones, it is easy to associate with "May 1 Labor Day", "five fingers to grasp", "I love Wuzhishan, I love Wanquanhe", etc. Wait. But it is generally not easy to think of breaking it down. This number can be decomposed into the product of two prime factors: 11111 = 41 & times; 271.

These two prime factors are relatively large and can be seen at a glance. Write the two prime factors to become 41271. As the second-level password, you can add another secret to get some time to take remedial measures.

If you are worried that the password cracker will also think of the decomposition factor, you can increase the difficulty of decomposition. It is much more difficult to decompose the two prime factors. For example, it can be found from the prime number table that both 8861 and 9973 are prime numbers. Multiply them to get: 8861× 9973=88370753.

Use the product 88770953 as the first password to form the first line of defense; write the two prime factors to 88619973. As the second password, this second line of defense is not a general thief can crack. Even if I think of trying to decompose the 83701753 to the prime factor, even if I use the electronic calculator to help with the division, if I don't have a detailed quality table at hand, I can try it out one by one and can't wait to get to 1000, I may lose confidence and quit halfway.

The quality factor is so big. If you forget your password, you can't crack it yourself. Isn't it asking for trouble?

Of course, this is an early arrangement when making passwords. . Choosing the above two large prime numbers 8861 and 9973, we have pre-determined the trick: as long as you use the homophonic method, read them as "Daddy pays attention, 舅舅 伞 伞", you can remember it.

With this simple method, it is easy for everyone to write a double password that only you know.

If you use an electronic computer, it is very easy to decompose a small number into a product of the prime factor. However, if this number is too large and the amount of calculation exceeds the capacity of the usual microcomputer, the computer will be out of reach.

In 1977, three scientists and computer experts designed one of the world's most difficult password locks. They estimated that humans would need 40 40 million years to unlock their passwords. In doing so, they want to show the government and the business community that using long mathematical passwords can protect top-secret information stored in computer databases, such as Coca-Cola formulas, nuclear weapon equations, and so on.

The principle of their passwords is basically the method of decomposing the prime factor described above, but their numbers are very large and large, not a five-digit 11111 or an eight-digit 88370753, but a The number of 127 digits made any computer at that time sigh.

Of course, the three experts who compiled the password lock, Reefster, Shamel and Adelman did not think that the science would develop so fast. After only 17 years, 600 experts from five continents used 1600 computers, and with the help of the computer network, they worked hard for 8 months, and finally solved the super password lock that is said to be hard to break for hundreds of millions of years. It turns out that the one hidden under the password lock is such a sentence: "The curse is a nervous vulture. ”

It doesn't matter what the lock is locked, it's important that the lock is very difficult to open. It doesn't matter what you get when you open the password lock. It's important to be able to overcome the difficulties that are difficult to overcome.

The popularity of computer networks has enabled every user to view the useful information provided by computers around the world by simply pressing the keyboard while sitting at home. But be careful, the world is so big, in case any mischievous children break into your computer through the Internet, messing up and messing up, the data stored in the computer will be lost. Just like the door lock, the computer that is connected to the network is equipped with its own password lock. Prime numbers are an ideal tool for creating passwords.
