How to construct a password with high strength

A password is a string of characters used to access information or a computer. Passwords are usually longer than passwords to increase security and contain multiple words to create a phrase. Passwords and passwords help prevent unauthorized access to files, programs, and other resources. When you create a password or password, you need to make it powerful, which means it's hard to guess or crack.

In wireless networks, a key to Wi- Fi protected access (WPA) security supports the use of a password. This password is converted into one for encryption, which is invisible to you.

In addition, let's take a look at the following case: at the end of 2009, a dating site was hacked and lost all its data. among the published passwords, the following 10 are the most frequently used:

1 、 123456

2 、 12345

3 、 123456789

4 、 password

5 、 iloveyou

6 、 princess

7 、 rockyou

8 、 1234567

9 、 12345678

10 、 abc123

As can be seen from the above, most people do not pay much attention to the security of passwords. As for the consequences of losing a user name and password, you can refer to my other post: http://nearlv.blog.51cto.com/2432295/1154669

This article focuses on how to make a password or password powerful?

A strong password should include:

At least 8 characters long

Does not contain your user name, real name or company name

Does not contain a complete word.

Cannot have the same password as before

A powerful password:

Between 20 and 30 characters

Is a series of words, create a phrase

Does not include common phrases found in literature or music

Does not include words found in the dictionary

Does not contain your user name, real name or company name

Significantly different from previous passwords or passwords

Powerful passwords and passwords contain the following four types of characters:

Character type

Capital letters: (a, B, C)

Lowercase letters: (a, b, c)

Number: (0, 1, 2, 3, 4, 5, 6, 7,. .)

All the symbols and spaces on the health plate: (`,! , @, #, ¥,%, $,%, ^, &, *, (,),... (.)

Note: a password or password may meet all the above criteria and is still weak. For example, Hello2U! Meet all the criteria listed above for a strong password, but it is still weak because it contains a complete word. If you change "o" to "0", it becomes Hell02U! Or H3ll02U! This becomes a powerful password because it replaces letters and numbers in some complete words, including spaces

Note: many people will ask, it is so complicated, it is difficult to remember, the following methods can help you remember these complex passwords and passwords.

1. Create an abbreviation for information from an easy-to-remember piece. For example, pick a phrase that makes sense to you, such as my own birthday, is October 12, 1987. Using this sentence as a guide, you can use your password 87 Mobi12/Oct

2. Replace numbers, symbols, letters or a phrase that is easy to remember. For example, my own birthday is October 12, 1987. I can use Brthd0te1012*87, and the strength of the password increases all of a sudden.

Of course, if you feel you have to write down your password or password to remember it, you can write it down and keep it in a safe place!
