I am a cross-platform user, is it possible to access BitLocker encrypted external hard drive and flash drive from other platforms, like Windows Mobile, Android, Surface, Linux, Mac OS X?
Bitlocker for Mac OS X - M3 Bitlocker Loader for Mac
Although Microsoft only developed and released Bitlocker for Windows version, so Mac OSX cannot open Bitlocker encrypted drive, but with the help of M3 Bitlocker Loader for Mac, you can easily open Bitlocker encrypted drive and then read/write Bitlocker encrypted drive on Mac Mini, Mac Pro, MacBook, MacBook Pro, MacBook Air, iMac with macOS 10.13 (High Sierra)/10.12 (Sierra) and Mac OSX 10.11/10.10/10.9/10.8/10.7 Operating Systems.
Bitlocker for Linux, Ubuntu
Dislocker - FUSE driver to read/write BitLocker encrypted volume in Linux. Dislocker is a tool to decrypt BitLocker encrypted volume from Linux developed by Romain Coltel. Dislocker uses a fuse based mechanism to decrypt the volume and mount it so that the user can access (read or write) the files within the volume. Note that this is not a brute force mechanism or hack; the user still needs to provide a valid BEK file (startup key) or numerical key or FVEK (Full Volume Encryption Key) or recovery password or user password for the decryption. Dislocker requires the PolarSSL library to work.
Bitlocker for Windows
BitLocker is a full disk encryption feature included with selected editions of Windows Vista and later in January 2007. It is designed to protect data by providing encryption for entire volume. By default it uses the AES encryption algorithm in cipher block chaining (CBC) mode with a 128-bit or 256-bit key.
Bitlocker drive encryption is available in Windows Vista Ultimate/Enterprise, Windows 7 Ultimate/Enterpise, Windows 8 Professional/Enterprise, Windows 10 Professional/Enterprise, Windows Server 2008, Windows Server 2012 and Windows Server 2016.
Bitlocker for Surface
In Surface, this feature called device encryption, it is an advantage over the Surface Pro line, like the Surface RT, Surface 2, Surface 3 or SurfaceBook. The Windows RT version of Bitlocker is turned on by default and automatically saves a copy of your key to your Microsoft account as soon as someone with a Microsoft account and admin rights signs in to the machine.
Bitlocker for Windows Mobile
In Windows Mobile, the feature is called Device encryption, and it helps to make local device data unreadable for anyone who attempts to access it without authorization. The primary reason Microsoft is adding this feature is to protect your confidential data if your device is lost or stolen. Using the encryption feature only the person with the right encryption key (your password) can make files and folders readable.
Bitlocker for Android
Bitlocker is not available in Android, so Bitlocker encryption must be disabled before accessing Bitlocker encrypted drive in Android.
