What It Does

A SecureDisc Decryption Client is required to read SecureDisc encrypted CDs and DVDs on computer systems running Microsoft Windows. 

If you received your disc from a third party, please contact the disc provider’s help desk for assistance with installation, configuration and passwords. All disc contents and passwords are the responsibility of the disc provider. GTGI cannot retrieve a lost password or provide support for any viewer or database access software provided by the disc provider.

Having Problems Decrypting a Disc?

WINDOWS 10 USERS: If you are having issues with the Resident Client on Windows 10, before contacting GTGI Support, please download and install the latest version (3.0.2-WHQL) first. Before installing the new version, remember to uninstall any previous versions.

Please refer to the SecureDisc Decryption Clients FAQ below for a list of common problems and possible solutions. If you need a full manual for the Decryption Clients, please refer to the SecureDisc Client Guide. The Guide has descriptions of all common error messages and dialogs in our SecureDisc Decryption Clients.

If your issue is not addressed in the SecureDisc Decryption Clients FAQ or the SecureDisc Decryption Guide, please contact your disc provider.

Older SecureDisc Resident Client Versions

PLEASE NOTE: These older versions of the SecureDisc Resident Client are being provided as a service to our customers who need to decrypt discs on older versions of Windows. We do not recommend them for new installs, as they do not support 64-bit Windows.

Frequently asked questions

SecureDisc utilizes a 256-bit AES cryptographic engine which provides the highest level of security recognized by commercial and government entities. Although no technology can claim to be ‘unbreakable,’ a 256-bit key is the closest commercially available technology to that theoretical goal. However, the encryption engine alone is not the sole component of a secure solution. SecureDisc encrypts the entire disc image. Picture this as taking all the files to be protected and placing them inside a virtual ‘safe.’ This is distinct from file-based encryption methods that individually ‘lock’ each file on the media. Encrypting the entire disc image creates a more secure solution since there is no visibility to any of the protected files until the image is decrypted by entering the correct password. This is one of an array of methods SecureDisc uses in order to prevent ‘cracking’ software from extracting the password and allowing unauthorized access. There are widely available software applications that can ‘brute force attack’ encrypted files by making thousands of attempts per second using every possible password combination and eventually obtain the password. These applications cannot be used to defeat SecureDisc, as every time an unsuccessful password attempt is made the disc is automatically ejected from the drive, requiring manual re-loading of the disc for each failed attempt.

SecureDisc uses a ‘disc-in-disc’ system that places the encrypted disc image inside a standard, non-encrypted UDF base file system. Using this system, SecureDisc can place decryption clients, documentation and other useful files in the non-encrypted base file system, while providing full security for files in the encrypted image. Also, since the encrypted image is simply a file on the disc, it requires no special permissions or disc features to access, preserving compatibility with end-user optical drives and making decryption client deployment much easier.

SecureDisc provides two different decryption clients, the Resident Client and the Explorer Client. Both present the same interface to the end user: When an encrypted disc is inserted, the decryption client will ask for a password. If a correct password is inserted, SecureDisc works in the background, decrypting files on-the-fly and providing drive-letter access. If an incorrect password is provided, SecureDisc will deny access and eject the disc.

The Resident Client uses a kernel-mode driver to perform decryption. This is more compatible with third-party viewers, but requires installation as an Administrator, and as such may not be suitable for all environments. The Explorer Client uses the built-in WebDAV redirector in Windows XP and above to mount the encrypted image as a network drive. This is not as compatible, but does not require intervention by an Administrator to work. Before deploying SecureDisc in your workflow, please evaluate both clients with your viewer software and your end users to see which one works best.

The Explorer Client makes use of Windows’ AutoRun system, and may not launch properly on systems that have AutoRun disabled.

There is a base license that is paid only once per system. The base license authorizes that system to produce encrypted discs and it never needs to be renewed. Updates within the major release purchased are covered under optional SAE. If a new major release is issued and an existing SecureDisc owner wants to purchase the new major release, SAE customers pay 50% off of the Commercial Price. 

Image Packs are bundled licenses that decrement every time a unique encrypted disc image is generated. Image Pack license keys are ‘plugged in’ to the SecureDisc base license.

Each disc encrypted with SecureDisc is counted as a “image”, and GTGI sells rights to encrypt images in packs of varying sizes, from 1,000 up to 25,000. How many you will need depends on your throughput. We offer complimentary units and licenses for testing and workflow development purposes; please contact us for more information.

Units are licensed per Control Center or “N” robotic unit, and are not transferable between machines without GTGI’s express permission and assistance; if you need to transfer units from a failed or replaced machine to a new machine, please contact us.

We no longer split image packs between machines. Please purchase a separate image pack for each machine you plan to encrypt on.

SecureDisc does not generate or manage passwords, rather, it encrypts using a password provided by your workflow. There are 4 ways to introduce an encryption password:

– Inside the job production order

– Include with disc content (inside a password text file, password blanked before recording)

– Use a fixed, global password (every disc has the same password)

– Use an extra merge field in the label file (password is automatically blanked before printing)

We can also provide ODBC database integration at an extra cost.
