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:<\/p>\n

\"Log.JPG\"<\/p>\n

To check what protectors were used, you can get a list of protectors for your BitLocker encrypted volume using the following steps:<\/p>\n

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:Windowssystem32>right-click on the line and paste the following:
C:WindowsSystem32manage-bde.exe -status X: , where X is the volume or partition letter<\/p>\n

You should get the answer like the following:<\/p>\n

\r\nC:pk-test-cases>C:WindowsSystem32manage-bde.exe -status f:\r\nBitLocker Drive Encryption: Configuration Tool version 6.1.7601\r\nCopyright (C) Microsoft Corporation. All rights reserved.\r\n\r\nVolume F: [New Volume]\r\n[Data Volume]\r\n\r\nSize: 4,88 GB\r\n BitLocker Version: Windows 7\r\n Conversion Status: Fully Encrypted\r\n Percentage Encrypted: 100%\r\n Encryption Method: AES 128 with Diffuser\r\n Protection Status: Protection On\r\n Lock Status: Unlocked\r\n Identification Field: None\r\n Automatic Unlock: Disabled\r\n Key Protectors:\r\n Password\r\n Numerical Password<\/pre>\n
If you do not have "Password" mentioned under "Key Protectors", then Passware Kit cannot assign Brute-force attack on your BitLocker encrypted volume. <\/p>\n
We can only recommend you to try searching for the protectors used on other devices and disks.<\/p>\n<\/p><\/div>\n
