Protecting your Flash ActionScripts can be a difficult task. Flash file format (SWF) is an openly documented format and there is increasingly a market for products which manipulate SWF files with the aim of extrapolating the ActionScript code within the file. Given almost any SWF file products such as ActionScript Viewer can extract all the ActionScript, rebuilding a mock-timeline showing interconnections between elements of the SWF and their code.
