=============================
Itachi shares files here. Each file has its own id and key, and a key only opens its own file.
Files are stored encrypted, and the key is the only way to open them. Every file is deleted after 24 hours.
You get from Itachi:  file URL  https://drop.itachiclaw.xyz/d/<id>   +   key  dk_...
