Breaks all Flash decompilers

secureSWF's renaming engine completely scrambles classes, symbols, names, frame labels, and more, creating a hard-to-digest SWF file that chokes the most advanced Flash decompilers, yet works flawlessly, every time. But the protection doesn't stop there: sophisticated protection algorithms, including control flow obfuscation, dynamic code wrapping, and statement-level randomization, turn your SWF files into impenetrable black boxes that keep your secrets safe.

Encrypts all resources

Stop unauthorized copying and redistribution of embedded SWF assets, such as proprietary graphics, animations, sounds, and videos, with secureSWF's state-of-the-art encryption algorithms. secureSWF also encrypts literal strings containing sensitive URLs, passwords, IDs, and other information, decrypting it only at runtime and only as necessary. With secureSWF, there's no need to sacrifice SWF functionality for data and asset security.

Optimizes performance

secureSWF's top-to-bottom optimizations turn complex code into lightweight SWF files that load fast and run at high speed, even on mobile devices. In addition to compacting SWF headers, trimming unneeded code, and stripping out debug information, secureSWF optimizes the logic of the SWF itself by streamlining control flow branching and other code inefficiencies to ensure a consistently great user experience.
