What is CRC SHA? Is it safe?

Nothing is more annoying than download and installing a big software only to find out you didn’t download the whole thing. So checking the integrity of files during and after downloads is a rather important thing, especially if you’re dealing with big files.

In this article, we’re talking about CRC SHA, whether it’s safe or not, and how can you get rid of it from the Windows context menu.


What is CRC SHA?

CRC stands for Cyclic Redundancy Check and is used in digital networks to check data against accidental changes. To add to this, SHA stands for Secure Hash Algorithm and is used to check data integrity. The National Security Agency developed SHA in 2010 has since then been widely adopted to verify data integrity.  

Together, the system can generate hash codes for files that can check integrity safely after a download or change in location. The hash code changes with any change, regardless of how minimal in the file and hence, this can indicate any change or damage to the file.

The short answer is yes; it is safe. The whole concept is about checking whether the files you transfer or download are safe and untampered with. 

The option shows up in the Windows context menu when you install 7Zip. The tool allows you to generate and check hash codes for any file. However, if you want to get rid of the CRC SHA option from the context menu, here’s how.

Step 1: Open 7Zip, head over to Tools and click Options.
