Convenient hosting of small files

I want to quickly and thoughtlessly upload small files: from the context menu of the file, in a couple of clicks, without memorizing and recording the link to it.
For what? So that at any time from any place with the Internet just take this file or verbally convey its “address”.
How? My concept below.

We need the name of the site easier - something like kalabala.ru (without a chance to be mistaken in writing).

It should look something like this:

That is one input field, an ad unit (well, should it pay off somehow?) And a tiny registration button.
')
When registering (with captcha, probably?) With a nickname and, probably, some other data, a certain application is generated as a key (cross-platform would be in high esteem) or something else.
It is installed only in the context menu (is it possible?).

Now when you click on a menu item, for example, “Pour into Calabal”, a window appears asking you to enter a password, which is easily passed.

Everything! Now I, or someone, comes to a simple kalabala.ru, drives a well-known “MagaDann” and receives a link to the last file I shared (if this is a picture, then a picture) and a chronological list of other files:

Password for the case when a certain file should not be seen by strangers - perhaps there are other options; somehow customizable option.

In general, the main point - no links and bulky sites.

Ps. It is inspired not bad working and the service lit on Habré.
Otherly googled - to no avail, perhaps ineptly.
