Proof of Authorship. How do you do it?

Lately I have been thinking on how to properly, and globally, sign files and code I make, as to watermark that I did X thing.

Lately I have been using GPG on RSA 2048bit to sign a .7z on AES with a long password that contains an validation file, as my proof of work, that I cypher in texts and files, even as my submission name at times.

Example: Project credits (movie or game)
Name: $random_cypher_I_made_for_company

Leads to pastebin or some place with the GPG, and they can extract the .7z with my public key. We can exchange our signatures for hashes, and be done with it. But if they require additional verification, the encrypt the .7zip with their own key, I decrypt, open the file with my knowledge based password, encrypt the validation file, and send it back as proof, that I am, without a doubt, the person in question.

Long ramble short: What do you use?

What is the standard?

Am I doing this correctly?

If we want to be the authors We will be the authors.

Well, I do write stuff, make songs, videos, movies, work on games, etc.. And do sign it this way. But I want to know, how people do this, normally.

Unless I am over thinking it.

I want to know your opinion, even if you don't ever want proof you did something.

True artists don't reveal their identities.

Who was the man who coded the mona lisa? Who wrote the Goldberg variations? We may never know, as history rightfully intended.

Good work!

Sorry, but if you can't understand one of the world's most beautiful software ever, I'm not sure you can call yourself a programmer?

I use personally distributed floppy disks.

I use anally distributed floppy disks.

I use anally distributed floppy dicks.

So, am I to assume then, no one here does this, at all?

how do you even get a job then?

>>14
I just tell them I wrote linux.

I'm a NEET.

You're a loony. How do you get a job sending all this cryptocrap instead of just a link to your github? Seriously.

>>17
"Loony". That's what my grandmother calls homeless people.

>>17
Sometimes I do link to my git repo on my server, it really depends.

But no one really does this?

>>18
I'm not homeless, I'm mobile.
