Encrypting drives with BitLocker
Encrypting Drives with BitLocker in Windows 11
BitLocker
is a built-in encryption tool in Windows 11 that allows you to secure your data
by encrypting entire drives. This is especially useful for protecting sensitive
information on laptops or removable drives. Here’s a comprehensive guide on how
to encrypt drives using BitLocker.
What is BitLocker?
BitLocker
Drive Encryption is a feature that encrypts the entire drive, making the data
inaccessible without the appropriate authentication methods, such as a
password, PIN, or recovery key. This protects your information from
unauthorized access, especially in case your device is lost or stolen.
System Requirements for BitLocker
Before
using BitLocker, ensure that your system meets the following requirements:
- Windows 11 Pro, Enterprise,
or Education editions: BitLocker is not available in the Home
edition.
- Trusted Platform Module
(TPM): A
TPM chip version 1.2 or later is required for BitLocker to function
effectively, although it can be configured to work without TPM in some
cases.
