Learn if CRC-SHA (7zip) that appears in Context Menu is safe or not. You will be able to remove CRC-SHA from Windows 10.

First, let’s start by talking about CRC. CRC aka Cyclic Redundancy Check is a technology that is present in digital networks in order to check accidental changes to the data. In other words, CRC is responsible for detecting unintentional changes happening in data of digital networks. They are usually based on the theory of cyclic error-correcting codes.

Cyclic codes are said to be very easy to implement anywhere but they also have the benefit of being suitable if you want to detect the burst errors (contiguous sequences of erroneous data symbols in messages).

SHA, which is short for Secure Hash Algorithm, is a cryptographic algorithm that is used in determining the integrity of a particular stash of data. The variations of the SHA are commonly used by SSL certificate authorities in signing certificates. This algorithm can be used to ensure that a website’s data is not tampered with by anyone. It ensures the safety of data by generating unique has values from any particular file. You can determine whether or not the file or the data has been tampered with by comparing the hash values to the hash value received after using this algorithm. The SHA was developed by the National Security Agency to verify whether the information you download from the internet is genuine or not.
