    How to: How to Use Cipher Command to Overwrite Deleted Data in Windows

    The Cipher.exe command-line tool can be use to encrypt and decrypt data on drives that use the NTFS file system and to view the encryption status of files and folders from a Command Prompt. Cipher.exe tool can be use to manage encrypted data by using the Encrypting File System (EFS).

    Microsoft has developed an improved version of the Cipher.exe tool that provides the ability to permanently overwrite (or "wipe") all of the deleted data on a hard disk. This feature improves security by ensuring that even an attacker who gained complete physical control of a Windows 2000 and later versions of Windows computer would be unable to recover previously-deleted data.

    IMPORTANT: Please note the following important information:

    • You must close all programs before you start Cipher.exe.
    • Cipher.exe is not a cure-all that makes it safe to store sensitive data in a plain-text format. Although you can use this tool to remove sensitive data from a drive, if best practices are followed, such data would not normally be created on the drive.
    When you delete files or folders, the data is not initially removed from the hard disk. Instead, the space on the disk that was occupied by the deleted data is "deallocated." After it is deallocated, the space is available for use when new data is written to the disk. Until the space is overwritten, you can recover the deleted data by using a low-level disk editor or data-recovery software.

    When you encrypt plain text files, Encrypting File System (EFS) makes a backup copy of the file so that the data is not lost if an error occurs during the encryption process. After the encryption is complete, the backup copy is deleted. As with other deleted files, the data is not completely removed until it has been overwritten.

    This tutorial will show you how to use the cipher command to overwrite deleted data on a hard drive in Windows 7, Windows 8, and Windows 10.


    EXAMPLE: Cipher command usage. The switch we are going to be using is the /w switch.

    To overwrite the deallocated data:

    1 Quit all programs.

    2 Open an elevated command prompt.

    3 Type following command and press Enter key:
    cipher /w:folder path

    Where folder path is the full path of any folder in the volume that you want to clean. For example, the Cipher /w:c:\test command causes all deallocated space on drive C to be overwritten. If C:\folder is a Mount Point or points to a folder on another volume, all deallocated space on that volume will be cleaned.


    You can use the Cipher /w:C command line command to remove deleted files permanently. To wipe deleted files from a drive other than C:, substitute the actual drive letter that you wish to scan.

    Data that is not allocated to files or folders is overwritten. This permanently removes the data. This can take a long time if you are overwriting a large amount of space.

  4. How to Use Cipher Command to Overwrite Deleted Data in Windows

    Can anyone solve this cipher?

    That doesn't seem credible to me. In the solve 408-cipher (mailed July 31, 1969), he used all of those characters ( L, backwards L, <, >) and they weren't directions inside the cipher, they were simply cipher characters. That's not to say he couldn't have changed it up but if you look at what he proposes, it doesn't really make any sense either. The 408-cipher had very few typos in it. It was in coherent sentences.

    What's unique about the above cipher is that, not long after he had the 340-cipher published (mailed Nov. 8, 1969), he published this (mailed April 20, 1970):
    "My Name Is..." Letter
    He calls himself "zodiac," he clearly wants people to solve the 340-cipher, and I believe he gave his name using the same cipher to help decipher it (clearly the intent of the text leading up to the 13-cipher). The problem is, those circled 8's don't appear in the 340-cipher. They are unique to the 13-cipher. I reason that this was deliberate. Coincidentally:
    Code: AEN+8K8M8tNAM _Z_O_D_I_A_C_[/quote] It fits like a glove and dodges all of the characters that are not in the 340-cipher. What that suggests to me is that every even index of character is junk data hiding the message. The non-junk data is what is posted above. Unlike the 408-cipher, it isn't just a little random, it is extremely random. That's what made me post this. I doubt I can solve it beyond the initial riddle. The more eyes looking at it the better.

    Encrypt a folder with Cipher

    Hi Comdervids,

    I’m Independent Advisor willing to help you. I would suggest to enclose the folder's name in quotations and use backslashes instead of forward-slashes like this:

    cipher /E C:\Desktop\Derek's things

    Or cipher /E C:\Desktop\"Derek's things"

    Or cipher /E "C:\Desktop\Derek's things"

    Best Regards,

    Angel.
