Many computer users over time, with a more detailed acquaintance, ask about hash sums. They are also called checksums. What is it? What is it for? How are these amounts calculated?
Definition
A checksum is a specific value that is calculated for data using special algorithms. The purpose of the hash is to verify the integrity of the data during transmission. The most common calculation algorithms are MD5, CRC32, and SHA-1. Checksums can also be used to compare data sets for nonequivalence, which is useful for detecting viruses on a computer.
