Overview

The cryptographic hash function is very useful for sharing information. When an organization needs to distribute programs or documentation

to customers, the organization can use the hash value to make certain the customer receives unchanged information. When you produce a

hash value for a data file, it is called a checksum. If you produce a checksum for files that customers will download, then your customers can

check for transmission errors. A checksum also prevents an attacker from disguising a malicious file as your original file.

To prevent these attacks, you'll need to produce a cryptographic hash function that is not susceptible to collisions. For example, some older

algorithm ciphers are hackable. In other words, a hacker can produce a checksum for a malicious version of a file that equates to the same

checksum as the original file. In this assignment, you'll research options to find and produce a cryptographic hash function that is not

susceptible to collisions. You'll deploy an appropriate algorithm cipher to encrypt. Then produce a checksum verification to increase the

security layers for a software application.
