Php crc32 calculates the 32-bit CRC (cyclic redundancy check) and crc32crc of the string.
Note: This article reprinted http://www.manongjc.com/article/499.html
The php crc32 function is used to generate a 32-bit Cyclic Redundancy checkcode polynomial of a string. This is usually used to check whether the transmitted data is complete. This article introduces the basic syntax and examples of php crc32 functions. For more information about the coders, s

We in the WIN10 system computer use, Lu Master is a lot of small partners are in use of scanning software, we can directly use to restore our computer, today saw a small partner in use when the WIN10 with the LU Master Ultra DMA CRC error Count, how to recover this problem, Today, I would like to share with you the effective solution to the WIN10 with the LU Master Ultra DMA CRC Error Count recovery method.
CRC Detailed verification code calculation
(Network engineer Exam required)
Example Description: 2008 second half of the morning question (18).
The CRC is used to test the error, the generation of the polynomial is G (X) =x4+x+1, the information code word is 10110, the computed CRC check code is:
A. 0000 B. 0100 C. 0010 d.1111

Python implements the method for calculating the resource icon crc value, pythoncrc
This article describes how to use python to calculate the resource icon crc value. The specific method is as follows:
The key to implementing this function is to parse the resource information, find the icon data, and then calculate the crc of the data.
