Encryption

In cryptography, Encryption is the process of encoding a message or information in such a way that only authorized parties can access it and those who are not authorized cannot. Encryption does not itself prevent interference, but makes it harder for the would-be interceptor to access the content.Encryption has long been used by militaries and governments to facilitate secret communication. It is now commonly used in protecting information within many kinds of civilian systems. Types of Encryption include symmetric-key and public-key encryption.
