flash - How to automatically decompile SWF file on my server?

Question

What language would I need to use?

A bit like http://www.showmycode.com/

And could anyone point me in the right direction to get started?

Answer 1

• SWFTools - SWF manipulation and generation utilities

  You can install SWFTools distribution (which has also a command line program), and use SWFExtract, that can decompile flash files.

  On OSX, install via: brew install swftools.

  This will install tools such as: as3compile, font2swf, jpeg2swf, pdf2swf, png2swf, swfbbox, swfc, swfcombine, swfdump, swfextract, swfrender, swfstrings, wav2swf.

  swfextracts allows to extract swf movieclips and objects out of swf files.

  Example to extract all:

  swfextract --outputformat "extract_%06d.%s" -a 1- sample.swf
  

• FFDec (GitHub) - JPEXS Free Flash Decompiler

  Opensource flash SWF decompiler and editor. Extract resources, convert SWF to FLA, edit ActionScript, replace images, sounds, texts or fonts. Various output formats available. Works with Java on Windows, Linux or MacOS.

  Examples:

  java -jar ffdec.jar myfile.swf
  java -jar ffdec.jar -proxy
  java -jar ffdec.jar -proxy -P1234
  java -jar ffdec.jar -export script "C:decompiled" myfile.swf
  java -jar ffdec.jar -selectclass com.example.MyClass,com.example.SecondClass -export script "C:decompiled" myfile.swf
  java -jar ffdec.jar -format script:pcode -export script "C:decompiled" myfile.swf
  java -jar ffdec.jar -format script:pcode,text:plain -export script,text,image "C:decompiled" myfile.swf
  java -jar ffdec.jar -format fla:cs5.5 -export fla "C:sourcesmyfile.fla" myfile.swf
  java -jar ffdec.jar -dumpSWF myfile.swf
  java -jar ffdec.jar -compress myfile.swf myfiledec.swf
  java -jar ffdec.jar -decompress myfiledec.swf myfile.swf
  java -jar ffdec.jar -onerror ignore -export script "C:decompiled" myfile.swf
  java -jar ffdec.jar -onerror retry 5 -export script "C:decompiled" myfile.swf
  java -jar ffdec.jar -config autoDeobfuscate=1,parallelSpeedUp=0 -export script "C:decompiled" myfile.swf
  

  Instead of "java -jar ffdec.jar" you can use ffdec.bat on Windows, ffdec.sh on Linux/MacOs
