This program was created for Flash developers who publish SWF files on the Web and wish to prevent unauthorized users from decompiling their work. The application features an intuitive interface, supports drag-and-drop action and gives you access to plenty of useful instructions.
All you need to do is drag-and-drop the SWF file you need to protect, select the preferred encryption mode (Basic, Exceptional or Intensified) and a destination folder and click the Encrypt button. Every encryption mode gives you access to additional options, each with a detailed description. The fact that it offers you info regarding all encryption options might prove to be of good use to average computer users who know little about this type of operations.
The application will immediately create a new directory containing the encrypted SWF file. You can then publish your creation online without worrying that an unauthorized user will decompile your SWF project and get their hands on your source code.
Cutting the long story short, you should buy this program if you're a Flash developer who needs to make sure no one uses your source code without your permission.
