AS3Obfuscator 1.1.1

ActionScript 3 obfuscator - obfuscates Flash
ActionScript source files - .AS and .FLA files,
making them very hard to understand, when viewed
with decompiler. Protects flash projects on source
level.

It's the only utility that can protect .FLA files
(frame actionscript, instances, classes), along
with .AS files. To do so it should work together
with Flash, as flash extension. Without Flash,
working as executable - obfuscates only .AS files.

The actionscript identifiers are mangled - renamed
irreversibly. Options say which type of
identifiers should be mangled (classes, vars,
functions, etc.). You can exclude from mangling a
list of specific identifiers. Also- if a type of
identifiers should not be mangled - you can
include a list.
In the exclude/include lists you can provide a
group of identifiers with wildcard character ("*"
character).

Optionally the strings can be encrypted in the
source files. In runtime they are decrypted.

Optionally the comments can be removed from the
actionscript code.

A problem with obfuscators in general is that they
can change a program's semantic. That is, it could
break - could happen if the program computes names
of variables/functions at runtime.
Imagine you obfuscate, and the program stops
working.
Any idea how to find a problem in obfuscated .swf?
With obfuscated source it could be possible to
locate the problem.
AS3Obfuscators permits finding original
identifiers from obfuscated (and to obfuscated).
Also, the source can be easy obfuscated again
after changing some of the options or ignoring
some identifiers.
AS3Obfuscators also tries to detect some simple
possible uses of computing identifier names at
runtime, so you do not need to add them in the
ignore list.
It can search for declared identifier names used
in a string
- Example: var myVariable; this["myVariable"]
String concatenation
- Example: this["my"+"Variable"]
Adding a number at the end
- Example: var i:int=0; this["myVar"+i]
