FileVault – an encryption program for Mac, used to save your data if your mac is ever stolen or misplaced, through encrypting hard disk. So, a misplaced Mac is not something to worry about. FileVault is whole-disk encryption which secures Mac by encrypting all the data at rest on its hard drive.

But for those who are not familiar with the FileVault encryption, this article will help them understanding it.

What is FileVault Encryption Mac?

Filevault is a term used for disk encryption specified for Mac. It was introduced with Mac OS X Panther (10.3) and since OS X 10.7 “Lion” is launched, it’s been in the current incarnation. Using XTS-AES 128 block cipher technology, FileVault secures your Mac’s hard disk. Whenever your Mac is started, you are required to put the password if FileVault is opened. Without entering the required password, the data is not recognized.

At the time of FileVault disk encryption, a password and a recovery key are given to enter in your Mac. Without this password, nobody could access the original data from the drive, even you yourself couldn’t reach the data.

However, the recent versions of OS X have given the users an opportunity to access their data using the iCloud account.

So, if you are concerned about your private data FileVault encryption provides you the secure way to protect data if your Mac is lost or stolen. Another great cause for which apple also recommends using FileVault is the opportunity of deleting data securely from Mac equipped with SSD whenever you stop using it.
