## BitLocker
BitLocker Drive Encryption is a data protection feature that integrates with the operating system and addresses the threats of data theft or exposure from lost, stolen, or inappropriately decommissioned computers. BitLocker uses the AES algorithm in XTS or CBC mode of operation with 128-bit or 256-bit key length to encrypt data on the volume. Cloud storage on Microsoft OneDrive or Azure<sup>[\[9\]](conclusion.md#footnote9)</sup> can be used to save recovery key content. BitLocker can be managed by any MDM solution such as Microsoft Intune<sup>[\[6\]](conclusion.md#footnote6)</sup> using a configuration service provider (CSP)<sup>[\[9\]](conclusion.md#footnote9)</sup>. BitLocker provides encryption for the OS, fixed data, and removable data drives (BitLocker To Go), using technologies like Hardware Security Test Interface (HSTI), Modern Standby, UEFI Secure Boot, and TPM. Windows consistently improves data protection by expanding existing options and providing new strategies.

Personal Data Encryption refers to a new user authenticated encryption mechanism used to protect user content. Windows Hello for Business is the modern user authentication mechanism, which is used with PDE. Windows Hello for Business, either with PIN or biometrics (face or fingerprint), is used to protect the container, which houses the encryption keys used by Personal Data Encryption (PDE). When the user logs in (either after bootup or unlocking after a lock screen), the container gets authenticated to release the keys in the container to decrypt user content.
With the first release of PDE (Windows 11, version 22H2), the PDE API was available, which when adopted by applications can protect data under the purview of the applications. With the next Windows platform release, PDE for Folders will be released. This feature doesn't require updates to any applications, and protects the contents in the Known Windows Folders from bootup until first sig-in. This reduces the barrier for entry for customers and they can get PDE security as part of the OS.
