→Code protection: Make it clear a decompiler can't retrieve the original code, rather it's a very close approximation |

==Code protection==
Like most [[bytecode]] file formats, Flash [[SWF]] files can be [[decompilation|decompiled]] into their source code and assets (similarly to how [[.NET Framework|Microsoft .NET]] files can be decompiled). Some decompilers are capable of nearly full reconstruction of the original source file,
In opposition to the decompilers, ActionScript [[obfuscated code|obfuscators]] have been introduced, which transform code into a form that breaks decompiler output while preserving the functionality and structure of the program. Higher-quality obfuscators implement lexical transformations such as identifier renaming, control flow transformation, and data abstraction transformation which collectively make it harder for decompilers to generate output likely to be useful to a human. Less robust obfuscators insert traps for decompilers. Such obfuscators either cause the decompiler software to crash unexpectedly or to generate unintelligible source code.{{Citation needed|date=March 2021}}
