Passware Kit shows “No password” or “Password not found” message in case no “Password” protection was set in BitLocker encryption. Mostly it means your BitLocker volume was encrypted with a Recovery Key which cannot be found with the brute-force method but only extracted from a memory image or hiberfil.sys. Please refer to the image below showing the Log in such cases:

To check what protectors were used, you can get a list of protectors for your BitLocker encrypted volume using the following steps:

1. Press “Start” button, write “cmd” in the search field, right-click cmd.exe and choose “Run as Administrator.
2. Press “Yes” in the appeared window
3. In the black window after C:\Windows\system32>right-click on the line and paste the following:
C:\Windows\System32\manage-bde.exe -status X: , where X is the volume or partition letter

You should get the answer like the following:

C:\pk-test-cases>C:\Windows\System32\manage-bde.exe -status f:
