irrFuscator 2.0.1
The ActionScript 3 Byte Code (abc) in .swf files still contains a lot of symbols revealing how your program works and what it does, so it is very easy to reverse engineer or steal your code. irrFuscator can be used in two modes:
SWF Obfusction (Binary): protects an existing .swf file.
Flex Obfuscation (Source): reads in a directory of .as and .mxml files, processes them and puts them out into a target directory. Simply recompile the directory with the obfuscated files and your .swf files are a lot safer.
