Sure, try to learn and engage with all information out there. I want to sort some things away to focus on more important things.

Actually, I want people to have the option to chose. That's all.

Yeah!

I remember calculating the numbers for making sprites, 24x21 pixels IIRC, that you then POKEd into the correct places in memory and then POKEd some more to show and move them around.

And you could copy over the ROM ASCII characters to RAM memory and modify them into blocks and stuff for a game, or a classic was to copy them twice but the second copy you merged them bit-shifted once to get fatter characters.

And don't get me started on the, for me at that time totally magic, interrupt to change sprites, background colors and more that you normally couldn't do even with your hand cranked mashine code...

What a time.

crypt.fyi - Secure Secret Sharing with Zero-Knowledge End-to-End Encryption in c/[email protected]

Thanks for the explanation!

Yeah, you could let the user encrypt the sensitive data with "your" public key for example (or use ssh I guess). For sharing keys, that's more complicated of course, especially if the person that is going to get the key doesn't know it will get the key beforehand (or the key can be encrypted with their shared public key).
