### Checksum a good checksumalgorithm typically outputs a significantly different value to the input data for small modifications

WHttps://en.wikipedia.org/wiki/Checksumhttps://zh.wikipedia.org/wiki/ChecksumA checksum is a small-sized datum derived from a block of digital data for the purpose of detecting errors which May has been introduced during its transmission or storage. It is usually applied to a installation file after it was received from the download server. By themselves, checksums is often used to verify data integrity but is not relied upon to verify data authentici

### Checksumalgorithm Analysis

Before looking at the computer network related books, every time you see the IP or UDP header checksum, are at a glance, thought quite simple, is not the sum of 16bit data. Recently in the study of "TCP/IP Detailed Volume 1: Protocol" This book, see the checksum is 16bit word binary anti-code and (Halo, did not pay attention to the original is anti-code and, it seems that the previous reading is not careful

### Detailed non-code IP datagram header checksumAlgorithm

When google is used to search for the IP datagram header checksum algorithm, the code is always displayed and the process is not displayed, so this article is available. If there is an error, please correct it. Leave this article omitted. The IP/ICMP/IGMP/TCP/UDP protocol has the same checksum algorithm. The

### Simple implementation of PE checksumAlgorithm

I wrote this blog a long time ago, because it is now moved to cnblogs, and after sorting it out, I will try again. I have been engaged in computer security/virus-related things (pure learning, do not do evil) for a few years before my work. The PE file format is required. Some PE files, such as drivers, are checked during loading to ensure the integrity of the driver files. There is a lot of information on how to verify PE files. Here is an article titled An Analysis of the Windows PE

### IP/IGMP/UDP checksumAlgorithm

IP/IGMP/UDP checksum algorithm and algorithm: the IP, IGMP, UDP, and TCP packet headers both have validation fields, and their algorithms are the same. The range of IP, IGMP, UDP, and TCP checksum: only the length of the packet header. When sending data, in order to calculate the packet inspection. Perform the followin

### IP Datagram Header checksumalgorithm

when using Google search IP datagram header checksum algorithm, always see the code, do not see the process, so there is this article, if there are errors please correct me. The article omitted a little, hehe IP/ICMP/IGMP/TCP/UDP and other protocols are the same checksum algorithm, the

### IP packet checksumalgorithm C # (formerly)

For the sake of pseudo IP, we specially made an IP package and used C # to rewrite the IP header checksum algorithm. Document 1: IP Header Format: Version Number (4 digits) IP header length (4 digits) Service type (8 bits) Packet Length (16 bits) Id segment (16 bits) Flag (16 bits) Survival time (8 digits) Transmission Protocol (8 bits) Header checksum (16 bits)
