CAD drawing encryption software SmartLock_B-type lock

SmartLock_B-type lock is a high-strength encryption tool specially designed for AutoCAD drawings. Its core principle is to convert drawing files into dynamic memory virtual screen impressions (i.e. "impression encryption") when AutoCAD is running, to achieve a protection effect that can only be viewed and modified. The encrypted file only stores graphic display data, and the original graphic entity structure is completely destroyed and cannot be restored even by developers, eliminating the possibility of reverse cracking from the bottom up.

CAD drawing encryption software SmartLock_B-type lock software highlights

Protection of design results: Prevent competitors from obtaining drawings through illegal means. Even if the files are copied, they cannot be used or modified.

Distribution to partners: When providing drawings to customers or partners, viewing is allowed but modification is prohibited to avoid engineering errors caused by misoperation.

Internal permission control: Within the enterprise, set differentiated permissions for different departments or positions (such as only allowing measurement but prohibiting printing) to prevent core data from being leaked.

CAD drawing encryption software SmartLock_B-type lock software features

Irreversible encryption technology

Impression encryption: After encryption, only the graphics display information is retained in the file, and the original DWG data structure is completely reconstructed, forming an unparsable virtual impression. Technically, the graphics cannot be restored by any means.

Anti-cracking design: Even if the encryption algorithm is disclosed, crackers still need to go deep into AutoCAD kernel programming, the development cycle takes more than half a year, and the cracked files are still unusable.

Anti-tamper and anti-theft pictures

It is forbidden to explode (decompose): When you try to explode graphics using popular online decomposition tools, all graphics will disappear completely.

Capture and insertion are prohibited: Key points (such as endpoints and midpoints) of encrypted drawings cannot be captured, nor can they be inserted into other files. Even if they are redrawn, it is difficult to copy them accurately.

Random scale interference: If you try to measure a drawing, the drawing will automatically change scale randomly, causing the measurement results to be completely distorted.

High fidelity and compatibility

Zero loss of the image: The color, line type, precise position, etc. of the encrypted image are exactly the same as the original image, ensuring that the design details are not lost.

Plug-in-free access: Encrypted files can be opened directly with AutoCAD without installing additional plug-ins, simplifying the distribution process.

Batch processing capability: Supports encryption of multiple files or entire folders at the same time. The encryption speed is equivalent to opening files in AutoCAD, greatly improving efficiency.

Extended security features

Print interference technology: When printing encrypted files, the output is pure black or garbled characters to prevent the content of the drawing from being leaked through printing.

Layer lock: Irreversibly lock specific layers to prevent key design layers from being modified.

CAD drawing encryption software SmartLock_B-type lock software FAQs

Encrypted drawings cannot be displayed on other computers

To open encrypted drawings on other computers, you need to ensure that the corresponding software environment is installed. Although no additional plug-ins are required to open encrypted drawings with SmartLock_B-type locks, sometimes they may not be displayed correctly due to incompatible AutoCAD versions or differences in system environments.

If it cannot be displayed on other computers, you can try to update the AutoCAD version or check the system environment settings.

The drawings are incomplete or garbled

This may be caused by the drawing containing a font file that does not exist or is not recognized on the other computer.

As a workaround, make sure the font files used in the drawing are installed correctly before encrypting, or select the automatic font replacement option when encrypting.
