[Qt-interest] QML compilation ?

[Jason H]

Actually, no. What they could do, is extract the content into files, then modify 
the exe, as to reference the now local files, then change the local files. 
Because they could just change "qrc:/file\0" to "file\0\0\0\0\0" the binary 
would still run. I could write a script to dump your assets out and modify the 
binary.

Writing it in C++ wouldn't fix it, unless you implemented an QAbtractFileEngine 
which used your own obfuscation layer.

Its not encrypted, but It would be more than a little difficult to modify.  I 
have in the past done a CRC check on the data just to make sure. But since the 
user would have to modify the exe file (or dll) in a pretty precise manner, 
unless it’s a high-security issue I wouldn’t worry about.  And frankly, if it’s 
that high of a security thing.. do it in C++ not QML J

Even so... is the QRC format encrypted in any way?
If I load it into a hex editor, will I just see a serialized QDataStream?

Because it has nothing to do with QUrl.

It should be mentioned (but isn't) in the QNetworkAccessManager docs.
