Amayeta SWF Encrypt v5.0.4 Free & Full Download

SWF is an open format and therefore there is a whole lot of documentation precisely describing the structure of the file on the internet (see the excellent Alexis SWF Reference). This is a good thing but it has a downside; if you are developing Flash related products and applications for a living you don't really want people to be able to decompile and see your code.

There are a couple of applications on the market that will decompile your SWF and even recreate the FLA file for you and, don't get me wrong, this has been a life saver in many circumstances and from that point of view these applications are a blessing. These applications will happily decompile any SWF and give you access to the actionscript and all the assets embedded in the SWF, isn't it neat ? Well not always.

If you have been struggling for a month or two to develop a component or a Flash application that will bring a smile to the face of many users it is legitimate that you would want to make a couple of dollars out of it. But now what can you do against the army of decompilers drooling at the brand new SWF demo that you dropped on your website? Well there are some solutions: You can try to develop a server side script that will generate an SWF dynamically (not really the fastest solution), you can make a video that will describe your product (not very interactive) or you can have a look at something which is a lot quicker, the encryption solution.

SWF encryption and obfuscation
First let's have a look at the definitions of encryption and obfuscation
Obfuscation is a technique used to complicate code. Obfuscation makes code harder to understand when it is de-compiled, but it typically has no affect on the functionality of the code.

Encryption refers to a technique of scrambling data, using special software, so that only a party with the ability to unscramble the message has access to it.
In the past many applications pretending to protect the actionscript code from decompilers have been defeated and no Flash developer wants to invest in a product that might be defeated in a month or two.
