How to Calculate a Cyclic Redundancy Check
The cyclic redundancy check (CRC) code is an error-detecting code that is generally used to detect changes in data. The cyclic redundancy check code is generally calculated by a binary long division method that can be implemented using simple hardware. The 32-bit cyclic redundancy check (CRC-32) is the most widely used CRC method. However, if you need to find the CRC for a file, using an online CRC calculator would be the best option.

Note down the calculated CRC value that appears. This value can be useful for finding whether the file has been altered. If the CRC remains the same for subsequent checks, then the file has not been altered. If there is a change in CRC, it suggests the file has been altered.
