Exercise 1 - Learn Encryption Algorithms with CryptoDemo

Communication over the Internet is susceptible to being read or modified by unauthorized parties using an array of hacking tools available online. Cryptography provides security and protection for data from being read, and it includes features that detect whether data has been altered while it is being transmitted over non-secure networks.

One of the technologies included in cryptography is encryption. Encryption uses keys like digital certificates (called certificates or digital IDs) or passwords to protect data by scrambling it, therefore making it unreadable to unintended parties. The keys can be self-issued or issued by a service called a Certification Authority.

With the keys now available, a user can restrict access to his personal data by applying encryption. Encryption is the process of converting plain text data into cipher text or encrypted form to protect information from being read by unintended personnel. Only authorized persons with the right encryption key like a password or certificate can decrypt it.

In this exercise, you will download and install a program for that illustrates the common encryption algorithms being used today by software vendors.
