That changed with FileVault 2, which Apple introduced with OS X 10.7 Lion.Р”Р‡ileVault 2 (which wasnРІР‚в„ўt referred to by Apple with the numbering) provides full-disk encryption using XTS-AES-128 encryption with a 256-bit key, able to keep away everyone who doesn't have the password to unlock the content stored on your Mac's startup disk. The original FileVault was launched in 2003 РІР‚вЂњ along with OS X 10.3 Panther РІР‚вЂњ and was applicable only to a user's home directory. This allows users to encrypt system partitions/drives on computers where the BIOS reserves a large amount of memory (provided that the AES encryption algorithm is used).Apple's first attempt at native encryption wasn't the best in its class. The minimum memory requirements for the TrueCrypt Boot Loader (AES) have been reduced from 42 KB to 27 KB (twenty-seven kilobytes) in Windows Vista/XP/2008/2003.

MAC OS X ENCRYPTION SOFTWARE UPGRADE

Note: If your system partition/drive is currently encrypted using a non-cascade encryption algorithm (i.e., AES, Serpent, or Twofish), a backup copy of the TrueCrypt Boot Loader will be automatically stored in the first drive cylinder when you upgrade to this version of TrueCrypt.

This will no longer be necessary after upgrading to this version of TrueCrypt (provided that the system partition/drive is encrypted using a non-cascade encryption algorithm, i.e., AES, Serpent, or Twofish). The affected users had to use the TrueCrypt Rescue Disk to repair the TrueCrypt Boot Loader.

Whenever the TrueCrypt Boot Loader is damaged, its backup copy is run automatically instead.Р”Р„s a result of this improvement, the following problem will no longer occur: Certain inappropriately designed activation software (used for activation of some third-party software) writes data to the first drive cylinder, thus damaging the TrueCrypt Boot Loader.

If a non-cascade encryption algorithm is used (i.e., AES, Serpent, or Twofish), the TrueCrypt Boot Loader is now small enough so that a backup of the TrueCrypt Boot Loader can be (and is) stored in the first drive cylinder.

When the system partition/drive is encrypted, the TrueCrypt Boot Loader is now stored in a compressed form and is, therefore, smaller.

Faster booting when the system partition is encrypted in Windows Vista/XP/2008/2003.

Increased speed of AES encryption and decryption in Windows.

Command line options for creating new volumes in Linux and Mac OS X.

Feature useful for users who want to backup or repair a TrueCrypt encrypted operating system from another operating system.

Ability to mount a partition that is within the key scope of system encryption without pre-boot authentication such as a partition located on the encrypted system drive of another operating system that is not running in Windows Vista/XP/2008/2003.

Support for hibernation on computers where the system partition is encrypted in Windows Vista/XP/2008/2003.

The TrueCrypt version 5.1 was released on Mahas the following new features, enhancements, improvements or bug fixes:

Encryption algorithms supported including AES-256, Serpent, and Twofish.

Provides two levels of plausible deniability, in case an adversary forces you to reveal the password: hidden volume (steganography) and no TrueCrypt volume can be identified (volumes cannot be distinguished from random data).

Encryption is automatic, real-time (on-the-fly) and transparent.

Encrypts a partition or drive where Windows is installed (pre-boot authentication).

Encrypts an entire partition or storage device such as USB flash drive or hard drive.

Creates a virtual encrypted disk within a file and mounts it as a real disk.

Although TrueCrypt is free, but itРІР‚в„ўs as powerful is not more powerful that other disk encryption utility available, and comes with more features than disk encryption program for BitLocker.

In essence, itРІР‚в„ўs a free alternative encryption software which only available for free to Vista Ultimate and Enterprise editions users, as part of Ultimate Extras package. TrueCrypt is a free open-source disk encryption software for Windows Vista, Windows XP, Mac OS X, and Linux.
