After a long time, I installed a 7 Zip new version over the WinRaR and find some entry in the Context Menu that was “CRC SHA”.

What is this and how to remove it from the Context Menu? Let’s discuss. 

Before we start, Let’s know about CRC and SHA somewhat. 

What is CRC SHA?

CRC is Cyclic redundancy check that is in the form of a code to detect the errors and used in digital network and storage devices to detect accidental changes. CRC is based on the cyclic error-correcting codes that are used for controlling the error in data. 

SHA

SHA is better known as “Secure Hash Algorithm” are the family of the cryptography hash function developed and published by the National Security Agency in the US.

These are some security features that help to keep the data secure. In the SHA family, there is a series of every next secure hash algorithm. Go to the Wikipedia page to learn more about it.
