Explain the basic concept of how information is encrypted.

The basic concept of how information is encrypted :

Encryption or encoding information to prevent it from being read by unauthorized parties has been the main use of cryptography since its early beginnings julius caesar for instance used an alphabetical code when communicating with his field commenders.

For encryption to work properly, both the sender and receiver have to know what set of rules(called the cipher) was used to transform the original information into its coded form(often called cipher text). Encryption is based on two components an algorithm and a key. A cryptographic algorithm is a mathematical function that combines plain text or other intelligible information> An algorithm is difficult to devise and can be used with multiple keys.
