BitLocker 크랙 해설: 키를 분실했을 때 효과적인 방법
Searching for a 비트 로커 균열 usually means one of three things: you have forgotten the password, Windows is unexpectedly asking for the 48-digit recovery key, or you want to know whether BitLocker cracking software can open the drive without either credential.
Here is the short answer: a properly configured BitLocker drive cannot realistically be brute-forced, and no legitimate tool can generate a missing recovery key from nothing. However, if you own or administer the device, you may still regain access by locating a recovery key that was previously saved to a Microsoft account, work or school account, USB drive, printed copy, Windows system, or another backup location.
이 가이드에서는 비트 로커 균열 differs from legitimate 비트락커 복구, which recovery methods actually work, and how Magic Recovery Key can search for BitLocker recovery information that may already be stored on an accessible Windows system.
Windows 7/8/10/11 및 Windows Server 지원
간단한 답변: You cannot normally crack BitLocker encryption or bypass it without valid authentication. Your practical options are to find an existing password, PIN, startup key, or 48-digit recovery password. Magic Recovery Key searches for previously stored recovery-key information; it does not break BitLocker encryption.

What Does “BitLocker Crack” Actually Mean?
문구 비트 로커 균열 is not an official Microsoft term. People normally use it to describe several very different situations:
- Cracking or guessing a forgotten BitLocker password
- Bypassing the recovery screen without a recovery key
- Finding a 48-digit recovery password saved somewhere else
- Extracting an existing key from an accessible Windows installation
- Removing BitLocker encryption after the drive has been unlocked
- Erasing a locked drive so that it can be reused
These actions are not equivalent. Finding a saved recovery key is legitimate key recovery; entering a valid key is normal unlocking; turning off BitLocker decrypts an already accessible drive; formatting erases the drive. None of these operations directly cracks BitLocker encryption.
This guide focuses only on recovering access to a device that you own or are authorized to manage.
Can BitLocker Be Cracked by Brute Force?
In normal recovery situations, brute force is not a practical way to open a BitLocker-encrypted drive.
BitLocker uses AES encryption with 128-bit or 256-bit keys. Depending on the Windows version and policy configuration, it may use AES-CBC or XTS-AES. A Microsoft-generated 48-digit recovery password also has enough entropy that systematically guessing it is not a realistic solution.
A user-created password and a generated recovery password are not the same. A short or reused user password may be weaker than a randomly generated recovery password, but online tools that promise an instant BitLocker password crack should still be treated with caution. They cannot universally unlock every BitLocker drive.
On TPM-protected system drives, firmware or boot changes may cause the TPM to withhold the protected key and send Windows into recovery mode. This does not mean BitLocker has been cracked or corrupted—it means Windows needs another valid protector, usually the 48-digit recovery password.
Therefore, the realistic recovery strategy is not to attack the encryption. It is to locate an existing password, recovery password, startup key, or securely backed-up copy of the required credentials.

실제 경험에 따르면 BitLocker는 종종 예기치 않게 트리거되는 경우가 많습니다. 드라이브가 “아무 이유 없이 잠겼다”고 생각할 수도 있지만, 다음과 같은 이벤트는 정기적으로 복구 프롬프트를 유발합니다:
- BIOS 또는 UEFI 업데이트
- 마더보드 교체
- 보안 부팅 변경 사항
- TPM 재설정 또는 실패
- 부팅 구성의 Windows 업데이트 변경 사항
- 자동 암호화(Windows 홈 디바이스)
- BitLocker 비밀번호 분실
- 실수로 삭제한 Microsoft 계정 자격 증명
이러한 시나리오에서는 사용자가 다음을 검색하게 됩니다. 비트 로커 균열 메서드를 사용할 수 있지만 올바른 접근 방식은 암호화를 우회하는 것이 아니라 복구하는 것입니다.

5 Safe and Legal Alternatives to a BitLocker Crack
1. Write Down the Recovery Key ID
Before searching for a key, record the Recovery Key ID shown on the BitLocker screen. The ID is not the recovery password and cannot unlock the drive by itself, but it helps you match the locked device with the correct 48-digit key when an account contains several saved keys.
2. Check Every Possible Microsoft Account
From another device, visit Microsoft’s recovery-key page and sign in with the Microsoft account used when the computer was first configured. Compare the Key ID displayed on the locked computer with the IDs listed in the account.
If someone else originally set up the PC, the recovery key may have been backed up to that person’s account rather than yours.
3. Check a Work or School Account
If the computer was ever managed by an employer, school, or other organization, contact the IT administrator. The recovery password may be stored in Microsoft Entra ID, Intune, or on-premises Active Directory. Provide the device name and Recovery Key ID so that the administrator can locate the matching record.
4. Look for a Printed, USB, or Saved Copy
Search USB drives, printed documents, cloud-storage folders, screenshots, password managers, email attachments, and other computers. A saved BitLocker recovery password may appear in a text file with “BitLocker Recovery Key” in its filename or contents.
Do not initialize, repartition, or format the encrypted drive while searching. Those operations will not reveal the password and may reduce your remaining recovery options.
5. Unlock the Drive with the Recovered Key
For a system drive, enter the matching 48-digit password on the BitLocker recovery screen. For a secondary or external drive, open it in File Explorer and select More options > Enter recovery key.
Advanced users can also unlock a volume from an elevated Command Prompt:
manage-bde -unlock E: -RecoveryPassword YOUR-48-DIGIT-KEY교체 E: with the correct drive letter. This command does not crack BitLocker; it unlocks the drive using a valid recovery password.
How Magic Recovery Key Helps—And What It Cannot Do
Magic Recovery Key is not BitLocker cracking software. It is a recovery-key finder designed to search for BitLocker recovery information that may already be stored on an accessible Windows computer or selectable disk.
It may help when:
- You previously saved or backed up the recovery key but cannot locate it manually.
- The computer contains several disks and you are unsure where the recovery information is stored.
- You want to check accessible system locations before considering destructive options.
- You need to copy or save a recovered key for future use.
To search for the key:
1. Install and open Magic Recovery Key on a Windows computer.
Windows 7/8/10/11 및 Windows Server 지원
2. 2. BitLocker 복구 키 를 클릭합니다.
3. Select the disk you want to check.
4. 4. 검색 and wait for the scan to finish.
5. If the correct key is found, compare its Key ID with the ID shown on the locked device.
6. Copy or save the 48-digit recovery password and use it to unlock the drive.
Important limitation: Magic Recovery Key does not brute-force BitLocker, decrypt a drive without valid credentials, or create a recovery key that never existed. If the required key was never stored on the accessible system and is not backed up elsewhere, the software may not find it. Check every disk and the associated Microsoft account before concluding that the key is unavailable.
What If No Password or Recovery Key Can Be Found?
If no valid password, recovery password, startup key, or backed-up credential exists, there is no supported method to decrypt the existing data. Microsoft Support also cannot recreate a missing recovery password.
At that point, your remaining options depend on whether the files are needed:
- If the files are important: Stop making changes, verify every possible Microsoft and organization account, check offline backups, and consult an authorized data-recovery or forensic specialist. Do not accept claims that guarantee a universal BitLocker crack.
- If the files are not needed: You can erase, repartition, or reinstall the drive and use it again. This removes access to the encrypted data; it does not decrypt or recover the files.
Formatting should therefore be treated as an erase-and-reuse option, not a BitLocker cracking method.
결론
A genuine 비트 로커 균열 is not a realistic solution for a properly encrypted drive. Brute-forcing a generated recovery password is impractical, and software that promises to unlock every BitLocker volume without a password or recovery key should be treated with caution.
The safe recovery path is to identify the correct device and Key ID, check Microsoft and organization accounts, search printed or saved copies, and look for previously stored recovery information. If you believe the key may still exist on an accessible Windows system, Magic Recovery Key can help search for it and save the result.
