what crc32 checksum

PHP Learning Series (1)--String processing function (3), PHP function 11, CRC32 () function computes the crc32 polynomial of a string. A 32-bit cyclic redundancy check code polynomial that generates a string parameter. This function can be used to

CRC32 Introduction CRC Verification Utility Library in the field of data storage and data communication, in order to ensure the correct data, we have to use the means of error detection. CRC is one of the most famous in many error detection methods.

Note: This article reprinted http://www.manongjc.com/article/499.html The PHP crc32 function is used to generate a string of 32-bit cyclic redundancy check code polynomial. This is typically used to check the integrity of the data being transmitted.

Network checksum Calculation 1. Preface Checksum calculation is the basic function of NAT and content modification. After performing these operations, you must modify the checksum in the Data header. 2. 16-bit checksum Calculation 2.1 Basic

First, IntroductionPt-table-checksum is one of the Percona-toolkit series tools that can be used to detect the consistency of the data in the master and from the database. The principle is to run on the main library, checksum the synchronized tables

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

Packet in the network transmission must be considered in case of data corruption, CRC32 and Adler32 are the most commonly used algorithms.Both go and Android are built into the implementation of these two algorithms, and the direct use is good.The
