If you are a Windows XP user, what do you do if you forget the wireless network password?
Generally, in such a situation, you will choose tools such as “Password Viewer” or ask the webmaster for help.
And if you are a Windows 7 user, you can use the tool or help the webmaster.
In other words, Windows XP cannot directly view the wireless network password, Windows 7 system is ok. So, what is the specific way to view the wireless network password in Windows 7 system?
Let's look at it together:
1. In the Windows 7 taskbar notification area, click the wireless network icon to slide out the current wireless connection menu;
2, select one you want to view the password. Link (don't look at it if it's not your own wireless connection, you can't see it unless you illegally crack it), right click on the property, this example takes "ruanmei" as an example:
3, click “ display characters & rdquo; items, the password of this wireless network is displayed in clear text!
This is not garbled, it is ASCII code, you need to push back to know the real password! For example, the real password corresponding to …………6B6B6B6B6B in the figure is KKKKKK.
This way, you can easily find out when you forget your password. However, don't check the password on someone else's computer.

The most widely used character set and its encoding in computers is the American Standard Code for Information Interchange (American Standard Code for Information Interchange), which has been adopted by the International Organization for Standardization. (ISO) is defined as an international standard called the ISO 646 standard. Applicable to all Latin alphabet letters, ASCII code has 7-digit code and 8-bit code two forms.
Because a 1-bit binary number can represent (21=) 2 states: 0, 1; and a 2-bit binary number can represent (22) = 4 states: 00, 01, 10, 11; and so on, 7 bits The binary number can represent (27 =) 128 states, each of which is uniquely encoded as a 7-bit binary code, corresponding to a character (or control code), which can be arranged into a decimal sequence number 0-127. Therefore, the 7-bit ASCII code is encoded with a seven-digit binary number and can represent 128 characters.
Nos. 0 to 32 and No. 127 (34 in total) are control characters or communication-specific characters, such as control characters: LF (line feed), CR (carriage return), FF (page change), DEL (delete) , BEL (ringing), etc.; communication-specific characters: SOH (text header), EOT (text end), ACK (confirmation), etc.;
No. 33-126 (94 in total) are characters, of which 48~ No. 57 is 0-9 nine Arabic numerals; 65-90 is 26 uppercase English letters, 97-122 is 26 lowercase English letters, and the rest are some punctuation marks, arithmetic symbols, and so on.
Note: In the storage unit of a computer, an ASCII code value occupies one byte (8 binary bits), and its highest bit (b7) is used as a parity bit. The so-called parity check is a method used to check whether an error occurs during code transmission. Generally, it is divided into odd and even parity. Odd parity stipulates: the correct code must have an odd number of 1 in a byte. If it is not an odd number, add 1 to the highest bit b7; even parity specifies: the correct code must be an even number of 1 in a byte. If it is not even, add 1 to the highest bit b7.
