selfpaste is a small self hosting paste service.
https://www.bananas-playground.net/projekt/selfpaste/
It is not the aim to replace any other well known paste service. 
It is an experiment and build for private use only.

This tool uses PHP fileinfo: https://www.php.net/manual/en/intro.fileinfo.php

It is not really bulletproof, but it does the job. 
Everything can be manipulated to look alike something it isn't.

So, here is a friendly REMINDER:

    - Use it at own risk.
    - Don't open it up to the public
    - Check regularly what is added
    - Clean everything what you do not know
    - You provide the service by hosting it. Your are responsible for it!
    - Change your secret often.

# Why json as a response?
In cases the upload is over post_max_size the request will not "arrive".
Meaning the script does not receive enough information to work with.
In this case it returns the start page. Which is a valid HTTP 200 status response.
So the client can not only rely on the HTTP status code alone.
