Public-key cryptography (2018)

idea-instructions.com

This is the only video that ever explained it concisely and clearly, IF you don't care about trying to actually implement it: https://www.youtube.com/watch?v=YEBfamv-_do

As a Swedish speaker, I cannot help but chuckle at the v1.1 update:

v1.1: Change title from PUBLIC KEY KRÜPTO to PUBLIK KEY KRYPTO to make it sound even more Swedish

Apart from Swedish speakers, the author may be the only person in the world who knows that Ü is, in fact, not a Swedish letter :)

That website is cool, but it flies closer to trademark parody/violations than I thought possible against a massive conglomerate like IKEA.

IKEA trademark looks completely different from the logo on this website. IKEA uses a rectangle with an oval and name in the oval.

The "digital signature" description gives the impression that the signed message is encrypted with the private key and later decrypted with the public key.

Is this how message signing works in reality? I had a different mental model.

They are separate operations.

  - encrypt with public, decrypt with private
  - sign with private, verify with public

Probably one of if not the most important technologies ever created.
