In cryptography, encryption is the process of transforming information referred to as plaintext using an algorithm to make it unreadable to anyone except those possessing special knowledge, usually referred to as a key. The result of the process is encrypted information (in cryptography, referred to as ciphertext). The reverse process, i.e., to make the encrypted information readable again, is referred to as decryption (i.e., to make it unencrypted). When the people use the Internet, they are not always just clicking around and passively taking in information, such as reading news articles or blog posts - a great deal of the user time online involves sending others one own information.
