Data Encryption:

The translation of data into a secret code. Encryption is the most effective way to achieve data security. To read an encrypted file, you must have access to a secret key or password that enables you to decrypt it. Unencrypted data is called plain text ; encrypted data is referred to as cipher text.  There are two main types of encryption: asymmetric encryption (also called public-key encryption) and symmetric encryption.  (Source: Webopedia)
