What is Encryption

Encryption is the conversion of data into a secret code which is called cipher text that cannot be easily understood by any unauthorized person. It is one of the most effective ways to achieve data security. A file after passing through encryption process is called an encrypted file and to read this encrypted file, the user must have access to a secret key or password that enables the user to decrypt it. (Decryption is the process of converting encrypted data back into its original form, so it can be understood). The unencrypted data is called plain text. » What is Encryption
