Can't convert pvr.ccz with content protection to png

[chongchaoyu]

If the pvr.ccz has been protected with a key, untp can't convert it to png successfully.
And I check the untp sources and the usage of TexturePacker, it has a "--content-protection" option, but this option looks like for encrypting the pvr.ccz, other than decryption.

Do you have some idea? Thank you!

Sorry for later, i think it's an good idea.

TexturePacker does not provide decryption option, we should implement it by ourself. Fortunately, the decrypt arithmetic is very simple, just xor ever bit with key. We could ref cocos implementation:

https://github.com/cocos2d/cocos2d-x/blob/v3/cocos/base/ZipUtils.cpp#L58

I'm interested in it, i'll implement it soon.
