Great video! The back and forth in the terminal was a great way to demonstrate how the increase in trust changes the output. I'm also happy to showed that --decrypt is a bit of a misleading option. This has really cleared up a lot of things for me that many other articles and videos didn't click for me.
I was a bit annoyed with the music though. I can understand wanting to have some filler sound, perhaps just don't mix it so loud. This of course was easily mitigated with my volume control ;-)

you do not have "Buy me coffee" anywhere or Buy me Beer would be relevant considering you are using Dezember (Mittwoch) as your date format. I can buy a coffee for you for a month. I think your mentor must be provide of you. And You are TEACHER, world is missing everywhere..
One dumbo question, at 15:12 you confirm this 'fingerprint' belong to you. But that i can as well say this finger print belong to me. How do I trust someone? Am I Missing something fundamentally? How do we ensure Fingerprint belongs to a person?

When I use the --sign option on a short text file and then cat it, I can read the original text in the resulting .pgp file. It's not the same as --clearsign in that it doesn't break the text out into a message section when it's cat(ed). Here's the beginning portion of the cat(ed) .gpg file:
$ cat testsign.txt.gpg
�r���

Am I doing something wrong? The email example in this video is completely obscured (although able to be decrypted by anyone) after --sign(ing) it.

When I try to "gpg --sign-key Id-user" with the yubikey I got this message:

"Really sign? (y/N) y
gpg: signing failed: No secret key
gpg: signing failed: No secret key

Key not changed so no update needed."
