What is FileVault Disk Encryption Mac
FileVault is a term used for disk encryption specified for Mac. It was introduced with macOS Panther (10.3), and since OS X 10.7 “Lion” was 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 your Mac. Without this password, nobody could access the original data from the drive. Even you couldn’t reach the data.
However, the recent OS X versions have allowed users to access their data using an iCloud account.
