Hi Brian,
You can decrypt your IVE file into a std::stringstream and use the
following code to read it from memory:
//Read IVE file from memory
osgDB::ReaderWriter *fileReader =
osgDB::Registry::instance()->getReaderWriterForExtension("ive");
if(fileReader) {
return fileReader->readNode(decryptedStream,options);
}
This might prevent people from using your IVE file, however they can
still easily get access to your texture/shader data. With a few clicks
of a mouse I can setup GLIntercept
(http://glintercept.nutty.org/index.html) to intercept all
texture/shader uploads to the graphics card and save them to a file.
Just thought you should be aware of this security hole.
