I have recently encrypted my Windows 10 Pro laptop system drive and removable backup drive using Bitlocker. I have obtained copies of the recovery keys in the form of text files and stored them in a secure location.
Additionally, I have also backed up these keys on Microsoft’s website using my login account. However, as a precaution, I would like to confirm that the backup keys will function properly in the event that I need to use them for recovery.
Can you tell me how I can verify that my keys match what the recovery system would require in a real recovery scenario?

Introduction
Bitlocker is a full disk encryption feature in Windows that provides protection for data on a computer. It uses Advanced Encryption Standard (AES) and is available in Windows 10 Pro, Enterprise, and Education editions. In case you forget your password or experience other issues, Bitlocker provides a recovery key that unlocks your encrypted drive.
However, it is important to confirm the validity of the recovery key to ensure that it works correctly in a recovery scenario. In this blog post, we will discuss how to validate a Bitlocker recovery key.
Locating your Recovery Key
Before we discuss how to validate a Bitlocker recovery key, let’s first understand how to locate it. When you enable Bitlocker on a drive, it gives you the option to save the recovery key to a file, print it, or save it to your Microsoft account. You should always save your recovery key in a secure location, such as an external hard drive, USB drive, or in a password-protected file on your computer.
If you have saved the recovery key to your Microsoft account, you can log in to your account and access the key from any device with an internet connection. To do this, go to account.microsoft.com/devices/recoverykey and sign in with your Microsoft account credentials.
Validating your Recovery Key
To validate your Bitlocker recovery key, you can use the manage-bde command-line tool in Windows. Here are the steps to follow:
Step 1: Open the Command Prompt as an administrator. To do this, right-click on the Start menu and select “Command Prompt (Admin).”
Step 2: Type the following command and press Enter:
manage-bde -protectors -get c:(Note: Replace “c:” with the drive letter of the encrypted drive.)
Step 3: Look for the “Numerical Password” field in the output. This is your recovery key.
Step 4: Type the following command and press Enter:
manage-bde -unlock c: -recoverypassword [numerical password](Note: Replace “[numerical password]” with your actual numerical password.)
If the recovery key is valid, you will see a message that says “The password successfully unlocked volume.” If the recovery key is invalid, you will see a message that says “The recovery password was not found in the system.”
Verifying Multiple Recovery Keys
If you have multiple Bitlocker recovery keys, it is important to verify each one to ensure that you have a valid backup. You can use the manage-bde command-line tool to verify each key individually.
Alternatively, you can use the Bitlocker Recovery Password Viewer tool, which is available in the Remote Server Administration Tools (RSAT) for Windows. This tool allows you to view all Bitlocker recovery keys that are stored in Active Directory Domain Services (AD DS) and helps you identify which keys are valid.
Conclusion
Validating your Bitlocker recovery key is an important step in ensuring the security of your data. By following the steps outlined in this blog post, you can confirm that your recovery key is valid and will work correctly in a recovery scenario. Remember to always keep your recovery key in a secure location and to verify it periodically to ensure its validity.
There are a few ways to validate a Bitlocker recovery key:
-
You can use the Bitlocker recovery key to unlock the encrypted drive and check if it is accessible.
-
You can use the command-line tool “manage-bde” with the -protectors -get command to check the recovery key against the key protector of the drive.
-
You can use the Bitlocker recovery key to decrypt the drive on another computer running Windows and check if it is accessible.
In any case, you should be logged in with your admin account, and the drive you want to check should be connected to the computer.
It is important to note that the recovery key is the last resort to unlock the drive, if the other methods of unlocking the drive such as password or smart card have failed. So make sure to keep the recovery key in a safe and secure place.
In order to verify that your recovery keys for your Bitlocker-encrypted system drive and removable backup drive are working properly, you can use a PowerShell command to do a quick comparison. To do this, you will need to:
- Open PowerShell as an administrator
- Run the command “manage-bde -protectors -get c:”
- Compare the password that is displayed to the key that you have saved and stored in a secure location.
This process allows you to confirm that the backup keys that you have saved will work in the event that you need to recover your encrypted drives. It is important to verify the keys as a precautionary measure to ensure that you can access your data in case of an emergency.
