Specific methods for viewing wireless network passwords in Windows 7

1. In the Windows 7 taskbar notification area, click the wireless network icon and slide out the current wireless connection menu

2. Select a link to view the password (if not your own wireless connection) Don't look at it, you can't see the neighbors unless you illegally crack it. In the above right mouse button, select the attribute. This example takes ruanmei as an example:

3. Click to display the character item, um, this wireless network The password is displayed in plain text!

What is garbled? Oh, this is not garbled, it is ASCII code, you need to push back to know the real password (click to enter: ASC code online query)! For example, the real password corresponding to 6B6B6B6B6B in the figure is KKKKKK.

Ok, finally, welcome everyone to the soft media company!

This way, you can easily find out your password when you forget it. However, don't check the password on someone else's computer.

Related knowledge: What is the ASC code?

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 American National Standards Institute (ANSI). The International Organization for Standardization (ISO) is 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; The 7-bit binary number can represent (27=) 128 states, each state is uniquely programmed into a 7-bit binary code corresponding to one character (or control code), and these codes 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) Characters, of which 48 to 57 are 0 to 9 Arabic numerals; 65 to 90 are 26 uppercase English letters, 97 to 122 are 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.
