View the wireless network password in Windows 7

If you are a Windows XP user and forget the wireless network password, what should you do?

Generally, in this case, you may choose tools such as "password viewer" or seek help from the network administrator.

If you are a Windows 7 user, you do not need to use any tools or seek help from the network administrator.

That is to say, Windows XP cannot directly view the wireless network password, but Windows 7 can. So, Windows
7. How does one view the wireless network password in the system?

Let's take a look at the following:

1. In the notification area of the Windows 7 taskbar, click the Wireless Network icon to slide the menu of the current wireless connection --

2. Select a link for you to view the password (if it is not your own wireless connection, you will not be able to see it, unless you crack it illegally), right click on it and select properties, this example uses "ruanmei" as an example:

3. Click "show characters". Well, the wireless network password is displayed in plaintext!

What is garbled? Oh, this is not garbled code, it is an ascii code. You need to repeat it to know the real password (click to enter: ASC code online query )! In this example ............ The actual password for 6b6b6b6b is kkkkkk.

In this way, you can easily find your own password. However, do not check the password on someone else's computer.

The most widely used character set and Its Encoding in computers is the American Standard Code
Information Interchange, American Standard Information Exchange Code), which has been set as an international standard by the International Organization for Standardization (ISO), known as ISO
646 standard. It is applicable to all Latin characters, including 7-digit ASCII code and 8-digit ASCII code.

Because the number of one-bit binary data can be expressed as (21 =) two states: 0 and 1, while the number of two-bit binary data can be expressed as (22) = four states: 00, 01, 10, 11, and so on. A 7-bit binary number can represent (27 =) 128 States. Each State is uniquely encoded as a 7-bit binary code, corresponds to one character (or control code), which can be arranged into a decimal number ranging from 0 ~ 127. Therefore, the 7-bit ASCII code is encoded using the seven-bit binary number, which can represent 128 characters.

0th ~ 32 and 127th (34 in total) are control characters or communication special characters, such as control characters: LF (line feed), Cr (Press ENTER), FF (page feed), del (delete), BEL (zhenling); Communication special characters: Soh (Text header), EOT (Text tail), Ack (confirmation), etc;

33rd ~ 126 (94 in total) is a character, of which 48th ~ Number 57 is 0 ~ 9. 10 Arabic numerals; 65 ~ The 90 is 26 uppercase English letters, 97 ~ There are 26 lower-case English letters, and the remaining are some punctuation marks and operator numbers.

Note: In a computer's storage unit, an ascii code value occupies one byte (eight binary digits), and its highest bit (B7) is used as the parity bit. The so-called parity refersCodeA method used to check whether an error occurs during transmission. Generally, there are two methods: Odd checksum and even verification. Odd check rules: correct code must contain an odd number of 1 bytes. If the number is not an odd number, 1 is added to the highest bit B7. Even check rules: correct code: the number of 1 in a byte must be an even number. If the number is not an even number, add 1 to the highest bit of B7.
