How to Encrypt Files and Folders Using BitLocker Drive EncryptionWhen we talk about security and theft of data, there is actually very little option available. Open source encryption facilities are not fully trustworthy. Now you are fully dependable on Windows BitLocker encryption technology.

What is BitLocker?

BitLocker is a drive encryption program designed by Microsoft that provides data protection for your computer. It uses data encryption technology to encrypt all data stored on the Windows volume. Suppose your computer is stolen, or if you don`t want someone else to access your computer, you can use BitLocker to encrypt all files on fixed data drives.

Compatibility

Windows computers running on Windows Vista or 7 Ultimate, Windows Vista or 7 Enterprise, Windows 8.1 Pro, or Windows 8.1 Enterprise supports BitLocker.

Requirements

BitLocker runs on above mention Windows OS versions; additionally you will require at least two partitions and a Trusted Platform Module (TPM).

A TPM is a microchip inbuilt on computer, used to store cryptographic information, such as encryption keys. Information stored on TPM is secured and safe from third party software attacks and physical theft.

TPM platform is used to protect Windows OS and user data, in case someone tries to tamper your computer when it is left unattended, lost or stolen.

Inside the working process

Your computer will   be protected by encrypting the entire Windows volume.

For this Windows uses TPM to lock the encryption keys that protects the data. TPM verifies the encryption keys whenever someone tries to access your computer. Encrypting the entire volume protects all of the data, including the operating system itself, the Windows registry, temporary files, and the hibernation file. Because the keys needed to decrypt data remain locked by the TPM, an attacker cannot read the data just by removing your hard disk and installing it in another computer.

On computers without TPM compatibility, encryption can be still possible but not with the added security that is possible with TPM platform.

Most people don`t know that there is alternative of BitLocker called EFS (Encrypting file system). Difference between EFS and BitLocker is that EFS is used to encrypt files on single user per basis while with BitLocker you can encrypt the entire drive. Continue reading about EFS. They have provided comprehensive information about the software and how to use BitLocker to encrypt a folder.
