AutoLISP LSP Script Encryption (FAS/VLX) Online Portal
Direct navigation to objective in-depth evaluation and anti-audit.
Why Do You Need Professional Evaluation?
When you've worked hard to write a more efficient AutoLISP or Visual LISP Plug-in (.lsp), in order not to leak the plain source code during internal testing or package distribution, To prevent peers from maliciously stealing secondary packaging, it needs to be compiled into irreversible binary bytecode. (FAS) Or packaged as an application including a DCL interface (VLX) .
Referral Evaluation Standard
We perform rigorous performance benchmarks on global CAD cloud services. All recommendations are based on real-world test results. Links go directly to official channels.
Enterprise Security & Anti-Piracy Compliance Warning
AutoLISP The source code usually embodies the core efficiency improvement algorithm of the enterprise. Use third-party online'LISP Obfuscators' have a very high risk of source code being captured and retained in the cloud. We strongly recommend users to directly use the official built-in AutoCAD desktop client. Visual LISP The editor performs local lossless compilation and refuses to use unknown online compilation boxes..

AutoCAD Visual LISP IDE (VLIDE Official built-in compiler)
★ 9.9Pros
Cons
Verdict
The most formal and secure encryption and compilation environment officially provided by Autodesk, Ensure bytecode is consistent between CAD versions 100% Stable operation.
Visual Studio Code LISP Extension (Official new IDE)
★ 9.6Pros
Cons
Verdict
Microsoft and Autodesk jointly create a modern LISP development environment, It is the first choice to replace the old VLIDE command line compilation..
AnyConv LISP Compiler
★ 9.0Pros
Cons
Verdict
Only suitable for temporary temporary conversion of non-confidential simple function macros, complex LISP It is extremely easy for the type to be lost after conversion.
Enterprise Data Conversion Best Practices Guide
Local `(vlisp-compile)` fast compilation
Can be entered directly at the CAD command line: `(vlisp-compile 'rx "C:/path/to/my.lsp")` You can instantly output the encrypted `my.fas` file in the same directory., No need to open the IDE.
Create a VLX standalone delivery package
If your plugin contains multiple LSP files and DCL dialog box in VLIDE Select 'Package Application (Make Application)', All associated files can be solidified and packaged into a single .vlx file.
Prevent decompilation from secondary confusion
Use regular obfuscation tools to obfuscate local variable names before compiling into bytecode. (Rename variables to meaningless symbols) to achieve physical and logical double encryption defense.
Technical FAQ
Q: The compiled FAS file can be found in Haochen or Zhongwang CAD Load directly? ▼
Generally OK. Most IntelliCAD Base can directly load and run standard encrypted FAS drawing extensions. However, some advanced LISP An error may occur when running cross-platform.
Q: Files that have been compiled into FAS will be reverse-restored to LSP Source code? ▼
FAS It is a highly translated compiled binary bytecode, and there is no perfect'Decompiler'. Generally can only extract plain text strings and some system variables, Your core geometric algorithm logic is absolutely safe.
