* The SYSTEM_CODEINTEGRITY_UNLOCK_INFORMATION structure contains Code Integrity unlock state and validation token.
*
* **Purpose:**
*
* The UnlockId field is a 32-byte cryptographic validation token used to authenticate requests to temporarily
* disable Code Integrity (CI) enforcement. It works in conjunction with the three flag bits (Locked, UnlockApplied, UnlockIdValid)
* to control the application of code integrity bypass authorization.
*
* **Mechanism:**
*
* \b Token \b Generation: When needing to disable CI, a component (bootloader, recovery environment, or factory process)
* computes a 32-byte UnlockId using:
* - HMAC-SHA256 or similar cryptographic hash function
* - A kernel-embedded or TPM-stored secret key
* - Machine-specific data (boot state, firmware version, hardware configuration, etc.)
*
* \b Validation: The kernel validates the UnlockId by:
* - Recomputing the expected HMAC-SHA256 using its stored secret and machine state
* - Comparing against the provided UnlockId (32-byte comparison)
* - Setting the UnlockIdValid flag if the cryptographic match succeeds
* - Rejecting any token that fails validation
*
* \b Application: Once validated:
* - UnlockApplied flag is set (unlock request accepted by the kernel)
* - Locked flag may be cleared (CI enforcement disabled for this session)
* - Temporary bypass of code integrity checks is granted for authorized operations
*
* **Security Properties:**
*
* - \b 256-bit \b Token: The 32-byte (256-bit) size is standard for HMAC-SHA256 output, providing strong cryptographic security
* - \b Microsoft-Controlled \b Secret: UnlockId tokens are derived from a Microsoft-controlled secret key, preventing unauthorized bypasses
* - \b Machine \b Binding: Machine-specific data ensures tokens are valid only for the intended system
* - \b Temporal \b Scope: Unlock is session-scoped and typically used during controlled recovery or factory processes
*
* **Use Cases:**
*
* - \b Factory \b Reset (OOBE): Allow boot in non-secure mode during device initial setup and provisioning
* - \b Recovery \b Environment: Enable recovery tools to bypass CI during authorized system repairs
* - \b Secure \b Boot \b Bypass: Controlled disabling of code verification during authorized recovery scenarios
* - \b Development/Debugging: Microsoft-signed tokens for internal kernel validation and testing on development systems
*
* \note The UnlockId prevents unauthorized bypasses of code integrity protection and is only trusted after cryptographic validation succeeds.
* \note This structure is private to the kernel and not part of the public API.
* \note Available since Windows Redstone 4 (Windows 10 version 1803).

*
* **Format:**
* - Size: 32 bytes (256 bits)
* - Algorithm: HMAC-SHA256
* - Derivation: Microsoft-controlled secret key + machine state
* - Validation: Kernel verifies token before granting CI bypass
*
* **Validation Process:**
* 1. Kernel recomputes expected HMAC-SHA256 from stored secret and current machine state
* 2. Compares computed HMAC against the provided UnlockId (byte-for-byte)
* 3. Sets UnlockIdValid flag if match succeeds; fails otherwise
* 4. If validation succeeds, kernel sets UnlockApplied and may clear Locked flag
*
* **Authorization Scenarios:**
* - Factory Reset (OOBE): Token allows non-secure boot during device provisioning
* - Recovery Mode: Token allows recovery environment to bypass code verification checks
* - Development/Debug: Microsoft-signed tokens for test systems and kernel development
*
* \note Available since Windows 10 Redstone 4 (version 1803, NTDDI_WIN10_RS4).
