Using Peer-Purchased Texture Packs for free

If you go into the game folders after playing on a world with a custom texture pack and head into the Local PE cache section in premium cache ( %LocalAppData%\Packages\Microsoft.MinecraftUWP_8wekyb3d8bbwe\LocalCache\minecraftpe\premiumcache\resource ), you can easily compile the folder into an MCPACK and distribute it or just use it for personal usage, even without ever owning it. I understand that this may just be fine (since it involves entering game files), but I would suggest to add some form of rudimentary encryption or use some other format for the cache (as in recompiling it).
