AutoCAD Lisp signing command line tool

You maybe knew about AcSignApply.exe but did you know that command line tool is available too? It’s not so obvious because AcSignApply.exe is found in the installation folder of AutoCAD but AcSignTool.exe is not. AcSignTool.exe can be downloaded here and described here. It’s for AutoCAD 2016 but should work for AutoCAD 2017 too.

AcSignTool.exe

In AutoCAD 2016 it was added the ability to digitally sign lisp files (.lsp, .fas and .vlx). There is the GUI version, AcSignApply.exe (which gets installed in the AutoCAD install folder) to sign the lisp files.

AcSignTool.exe is the commandline version of AcSignApply.exe. It is meant for signing lisp files in a batch process. AutoCAD doesn't need to be installed.

You can find the usage instructions by entering AcSigntool.exe /?

Usage: AcSignTool -sign /file:[inputfile] /cert:[certificate] /time:[timestamp] /comment:[description]
