> Without cryptography the digital signature makes no sense Outside of the HN bubble, people are still happily scribbling ink on paper and calling it legally binding, blissfully unaware of the existence of a mechanism to mathematically prove that a specific person/key was responsible for that particular signature. Even as someone who is aware of that, I've never had to cryptographically sign a PDF. Ever. I've either dropped a scanned image of my handwritten signature onto a PDF and re-exported it or in rare/annoying cases where it's "required", printed out the document, physically signed it with a pen, scanned it, and passed it along to whoever is making me jump through those hoops.
