Question
You have been asked to implement a data integrity program to protect data files that need to be electronically downloaded by the sales staff. You have decided to use the strongest hashing algorithm available on your systems. Which hash algorithm would you select?
Solution
You would select the SHA-256 algorithm. This is currently one of the strongest hashing algorithms available. It produces a 256-bit (32-byte) hash, which is considered to be very secure. Here are the steps you would take to implement this:
-
Identify the data files that need to be protected. These are the files that will be downloaded by the sales staff.
-
Install a software or tool that supports SHA-256 hashing. There are many available, both free and commercial, and they can be found online.
-
Use the software or tool to generate a SHA-256 hash for each data file. This will be a unique string of characters that represents the contents of the file.
-
Store the hash values in a secure location. This could be a database,
