Objectives

Use a hashing program to verify the integrity of data.

Background $/$ Scenario

It is important to understand when data has been corrupted or it has been tampered with. A hashing program

can be used to verify if data has changed, or if it has remained the same. A hashing program performs a hash

function on data or a file, which returns a $($usually much shorter$)$ value. There are many different hash

functions, some very simple and some very complex. When the same hash is performed on the same data,

the value that is returned is always the same. If any change is performed on the data, the hash value returned

will be different.

Note: You will need installation privileges and some knowledge of the process to install Windows programs.
