Key Features of Auto File DRM Encryption Tool

  • Auto File DRM Encryption Tool was developed with EaseFilter Encryption Filter Driver(EEFD) SDK.
  • The tool can encrypt the file transparently, enable you to embed the digital rights management( DRM) data to the encrypted files, it allows only the authorized processes or users to read the encrypted file, the unauthorized processes or users only can get the raw cipher text of the encrypted file.

How to Setup Auto File DRM Encryption

The EaseFilter DRM Tool allows you to automate file protection by defining secure folders and access policies. Follow these steps to secure your sensitive documents:

  1. Configure the Encryption Folder
    Define a target directory (e.g., C:\SecureData\*) using a file filter mask. Any file created in or moved to this folder will be automatically encrypted using 256-bit AES encryption in real-time.
  2. Set Access Control Policies
    Establish a Zero-Trust model by blacklisting all processes by default. Then, explicitly whitelist trusted applications like winword.exe or powerpnt.exe to allow them to decrypt and read the file content.
  3. Embed DRM Metadata
    Enable DRM flags to add persistent protection. You can set an Expiration Date (after which the file becomes unreadable) or bind the file to a specific Computer ID to prevent it from being opened on unauthorized hardware.
  4. Test Secure Sharing
    Copy an encrypted file to a USB or email it. Attempt to open it with an unauthorized process (like a web browser or Notepad). The tool ensures the process only sees raw ciphertext, while authorized processes on a machine with the SDK can view the original content.
Pro Tip: Use the EnableEncryptionKeyFromService flag if you want to store your encryption keys on a remote server. This allows you to revoke access to a file globally by simply deleting the key from your database!

Frequently Asked Questions

The file remains encrypted. The EaseFilter DRM Tool uses persistent encryption, meaning the protection travels with the file. Unless the destination computer has the EaseFilter driver installed and the user/process is authorized, the data will remain unreadable.

Yes. By using the Flags_Enabled_Expire_Time DRM flag, you can embed an expiration date directly into the file header. Once that date passes, the driver will automatically block all decryption attempts, regardless of user permissions.

Yes. Since the encryption happens at the file system level, files are encrypted before they are uploaded to the cloud. This ensures that even if your cloud account is compromised, the files themselves remain secure and encrypted.

This usually occurs if the application you are using to open the file is not on the Whitelist. In a Zero-Trust configuration, you must explicitly add the process name (e.g., notepad.exe) to the authorized list in your filter rules.
