SWF Defender for Windows

SWF Defender provides you a simple custom user interface you have only some clicks to protect your SWF files. SWF Defender protects your ActionScript codes by obscuring them so decompilers cannot retrieve any useful code from protected SWF file. It allows you to select the strings in your SWF file, encrypt them in the SWF file using a very secure encryption algorithm.

It will protect your SWF files from being played offline or on other websites. Specify a list of domain names that you want your SWF files to be launched from. The domains you have locked the application to are encrypted inside the SWF files and will only be decrypted at runtime.
