Windows 7 interview-wireless network password

Wireless network technology has gradually developed and matured, but we have different ways to view different operating systems. How can we view passwords for WIN 7 systems?

Let's take a look at it with the Microsoft 7 family team:

1. In the Windows 7 taskbar notification area, click the Wireless Network icon to slide the menu for 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 the link and select Properties, this example uses ruanmei as an example:

3. Click the display character item. 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 push it back to know the real password click to enter: ASC code online query )! In this example, the actual password of 6b6b6b6b is KKKKKK.

Okay. Finally, welcome to the soft media company!

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

Related Knowledge: What is ASC code?

The most widely used character set and Its Encoding in computers is the American Standard Code for Information Interchange, which is developed by the American National Bureau of Standards (ANSI ), it has been set as an international standard by the International Organization for Standardization (ISO), known as the 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 21 =) two states: 0 and 1, while the number of two-bit binary data can be 22) = four states: 00, 01, 10, and 11; likewise, 7-bit binary numbers can represent 27 =) 128 States. Each State is uniquely encoded as a 7-bit binary code, corresponding to a character or control code ), these codes 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 character: LF line feed), CR carriage return), FF page feed), DEL delete), BEL zhenling) special characters for communications: SOH header), EOT suffix), 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 check refers to a method used to check whether an error occurs during code transfer. It is generally divided into two types: 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, 1 is added to the highest bit of b7.
