Introducing Encryption
 
 
Description
In cryptography, encryption is the process of transforming information (referred to as plaintext) using an algorithm (called cipher) to make it unreadable to anyone except those possessing special knowledge, usually referred to as a key. The result of the process is encrypted. Nowadays, term encryption is nearly of the same usage as the term - cryptography.
