Back to normal. I slept very well. I am ready for my long run.
The Sun is shining again. I will continue with my DIY. I need to return one of the raw materials. I failed with it again.
I read a lot yesterday. Half of the time the fiction book and the rest about signing and encrypting.
I think that I finally understood how openBSD is using it. The sets are verified by SHA256 checksum and is this checksum what is signed. I went to a mirror site, selected the 7.6 version and checked it by myself. In the folder I found the needed files: SHA256, SHA256.sig and the public certificate openbsd-76-base.pub. All I had to do is execute this command in the terminal: signify -V -p openbsd-76-base.pub -x SHA256.sig -m SHA256. I got the signature verified message.
Signature matches, then checksums are the same that were in the signing machine thus these are the same files that were in the signing machine.
I ran some experiments. Now I am signing my picture of the day. Well, not really. I copied the openBSD idea and I am signing the SHA256 of the picture. You can verify it with the public key. If the signature is verified, you will know that this is the file that was on my machine. One final question would be, do you trust me?
