I think you guys are making this harder than it needs to be.
In 2012-2013 I created the thread for my mod, the Heaven's Fall altered melee mod:
Heaven's Fall: Melee Gameplay Mod
This thread over many years had an EXE installer available to download the mod that would add basically an expansion. So you would have
Warcraft III.exe to run Reign of Chaos,
Frozen Throne.exe to run the Frozen Throne expansion, and
Heavens Fall.exe to run Heaven's Fall. Then in-game you would see the custom races on the Race Menu if you played Heaven's Fall.
As long as I always wrapped the relevant EXE within a ZIP file, it was fine.
Since the Warcraft 3 game no longer supports it, you can download Heaven's Fall as its own separate game here (roughly 150 MB download):

Well, I haven't used the tools section that much because I cannot find a deprotect/protect tools there.
Don't be silly. There is no such thing as a protected map. Protected maps don't exist.
This is a quote from the README file included with Vexorian's Optimizer:
You got to notice that "map protection" is not something I consider to exist, unless a tool that encryptyed the map and made wc3 require a special DRM-like hack to read the map is created . Although that is very feasible to happen, I doubt anyone would actually make it done.
There is no such thing and we don't talk about it. Opening MPQs and building custom World Editors, however, is something you might find that the Hive can easily help you with.
