In the realm of data security, BitLocker is a powerful tool offered by Microsoft. It provides full - volume encryption for Windows operating systems, safeguarding your data from unauthorized access. While there are graphical user interfaces (GUIs) to manage BitLocker, using the BitLocker command line can offer more flexibility and efficiency, especially for system administrators or those who prefer the command - line approach.

What is BitLocker Command Line?

How to Encrypt with BitLocker Command Line

To use the manage - bde commands effectively, you need administrative privileges. Right - click on the Command Prompt icon and select “Run as administrator.”

2. Select the Drive to Encrypt

Identify the drive letter you want to encrypt. For example, if you want to encrypt your D: drive, you can use the following command:

manage - bde - on D:

This command will start the encryption process on the specified drive. By default, BitLocker will use the standard encryption method. If you want to use a different encryption mode, you can add additional parameters. For instance, to use the XTS - AES 256 - bit encryption mode:

manage - bde - on D: - encryption XTS - AES256

You may also be prompted to set a password for the encrypted drive. This password will be required to access the drive in the future.
 

How to Decrypt with BitLocker Command Line

Just like with encryption, you need administrative rights.

2. Decrypt the Drive

To decrypt a drive, say the D: drive, use the following command:

manage - bde - off D:

If you have set a password for the BitLocker - encrypted drive, you will be prompted to enter it. After entering the correct password, the decryption process will begin. The time it takes to decrypt the drive depends on the size of the drive and the amount of data stored on it.
