The sender divides data into blocks of equal size and then adds the data of every block using 1’s complement arithmetic to get the sum. Refer to the image below to see the error detection process of Checksum. The Checksum is generated at the sender end, and on the receiver end, the Checksum is validated. So MD5 is open to vulnerabilities if the hacker swaps the file with a checksum value. MD5 : MD5 is a hash function that generates a checksum value, but it is not required for each file to have a unique number. The SHA-2 family consists of a total of six hash functions with hash values that are 224, 256, 384, or 512 bits. SHA-2 (224, 256, 384, 512) : This includes some changes from its previous version, SHA-1. SHA-1 : SHA-1 is a hash function that is not considered a secure hash function as of 2 0 1 0 2010 2 0 1 0. SHA-0 : SHA-0 was the first hash function of this type, but it was withdrawn briefly in 1 9 9 3 1993 1 9 9 3. Some of them are given below with a brief introduction: Many cryptographic hash functions are used by programmers to generate checksum values. Note : The Checksum is an error detection algorithm that appends redundant bits in a message for error detection and can work on any message length.

On the sender’s side, this method uses a checksum generator to generate a Checksum.Sometimes, a Checksum is also considered as a hash sum or hash value.Checksum is the redundant bits that are attached with actual data.The process of checksum error detection at both sender and receiver end is also illustrated with the help of an example.Types of Checksum error detection algorithms are also explained.The checksum error detection algorithm is described in this article.So this article comprehensively provides all the information on the checksum error detection technique. The Checksum is an error detection technique that detects an error in a transmitted message by appending redundant bits in the message. It is essential to perform error detection in data transmission. The name of that error detection algorithm is Checksum. We are here with one of the techniques used in data transmission for detecting an error.
