cocos luacompile -s /Users/hlsb/Documents/nnRoom/src -d /Users/hlsb/Documents/ios-s-rc -e -k 2dxLua -b NNROOM --disable-compile

/Users/hlsb/Documents/nnRoom/src 初始路径
/Users/hlsb/Documents/ios-s-rc 加密后的路径
2dxLua  key值
NNROOM   sign值

使用该命令加密后需要在C++调用：

LuaStack* stack = engine->getLuaStack();

stack->setXXTEAKeyAndSign("2dxLua", strlen("2dxLua"), "NNROOM", strlen("NNROOM"));
