What is BitLocker?

BitLocker is free software from Microsoft that allows you to encrypt your entire hard drive. It does this by creating a virtual encrypted disk within the physical disk. This is done in such a way that all data stored on the drive can only be accessed when using an authorized password. It is a good idea to use BitLocker with a password you have never used elsewhere.

When a drive is locked through BitLocker, it is not possible to access the data on the drive without the correct password. Even if the hard drive is removed from the computer and attached to another machine, it will be inaccessible.

BitLocker uses the advanced encryption standard (AES) with 128-bit or 256-bit keys to protect your data. AES is a very strong encryption algorithm that is used by the US government to protect classified information.

Types of BitLocker Encryption

BitLocker can utilize two types of encryption, 128-bit or 256-bit, depending on the operating system you are using. The different levels of encryption protect your data with different strengths of security. For example, a lower level would be fine for protecting the information you don’t need very securely. However, if you are storing classified government information, you would want to use a higher level of encryption.

On Windows 11, there are two types of BitLocker Encryption you can utilize:

BitLocker Drive Encryption – This type of encryption encrypts all the data on your hard drive. It is a good choice if you need to protect your data from unauthorized access.

BitLocker To Go – This type of encryption encrypts removable drives, such as USB flash drives or external hard drives. It is a good choice if you need to protect your data while it is being transported.

What are the system requirements for BitLocker?

In order to use BitLocker, your computer must meet the following system requirements:

  • Operating System: Windows 7 Enterprise, Windows 8 Enterprise, Windows 8.1 Pro, Windows 10 Pro,  Windows 11 Pro, Education, or Enterprise edition.
  • Hardware: Trusted Platform Module (TPM) version 1.2. For Windows 11, it is TPM 2.0.
  • To run BitLocker, you must have two or more partitions on your device. One is the system partition where OS is installed and others where other data is stored.
  • You must be logged in with the Administrator Account.
  • The computer’s motherboard should be in UEFI mode.

Though it has some limitations, such as not being available on all versions of Windows and only being compatible with TPM version 1.2 or higher, the benefits of BitLocker encryption far outweigh these limitations.

How do I unlock my drive with the correct password?

If you are using BitLocker Drive Encryption on Windows 11, the unlocking process is pretty straightforward. Just type in your password and click unlock. Unfortunately, if you are using BitLocker To Go on another OS like Windows XP or Vista, unlocking drives can be a little more difficult. You will need to type in the Recovery Key Code that you created when you set up BitLocker. If you have lost or forgotten your Recovery Key Code, you can use the ‘Find my recovery key’ feature on the BitLocker website to unlock your drive.

How much of your drive do I encrypt?

You should encrypt as much of your hard drive as possible for total protection and privacy.
