I really hate dealing with my printer (or any printer for that matter), so I make pretty liberal use of my drawing tablet at this point. I import the PDF into Krita, use the ballpoint pen brush, and sign. I export to PNG, then use an imagemagick script to rotate it some random number between 1-3 degrees, and add noise onto it to look like a scan.

It's a pain, but it's still less annoying than dealing with a printer.

Preview on Mac OS can do this. You hold your signature up to the camera and then it creates an image you can add to any pdf.

It is so handy, indeed! I really wish Apple spent some time to make users aware of things like this, which are baked into standard macOS software.

Preview has to be one of the most under-appreciated apps on MacOS. It implements so much handy everyday functionality that requires third-party software on Windows. Or did, last time I used Windows (admittedly some time ago).

Having moved from Germany to Austria I was pleasantly surprised that they have a functional national ID system that you can use to sign PDFs with a qualified electronic signature. Within Austria, they have been accepted everywhere so far.

When I tried sending such a document to a German insurance company, they refused to accept it. I ended up faxing the document :/

You can actually sign a PDF this way just using Preview on MacOS.

Honest question: As long as you say you signed it, and you say it's your signature, does it matter how real it looks?

IANAL, but this depends on the jurisdiction. In some places (e.g. Ontario, Canada), e-signatures are fine; often this is because the law explicitly says they have the same effect as a "wet" signature. In this case, "looking real" doesn't enter into it.

In others (e.g. Denmark), you don't even need to sign - merely stating your intent to accept a contract, and having a clear record of that intention, is enough. In this case, again, "looking real" is a non-issue; you can even send an email in some cases.

In yet others, you will definitely be asked for a "wet" signature, and a digital signature is not considered legally acceptable. Here looking real could matter; if your signature is obviously non-physical, it may be refused.

This also varies by situation. In some places, banks want to see a wet signature, _and_ will compare it with an existing wet signature they have on file. In this case, it very much matters how real it looks, where "real" means "matches this other real signature". (Does this make sense? Arguably no, but that's the way it currently is.)

What's the use case of this? Signing documents with visual signatures instead of cryptographic ones is already extremely archaic, but having to make them look like being signed by hand is absurdly so.

It says right there in the description

> For bureaucratic reasons, a colleague of mine had to print, sign, scan and send by email a high number of pages. To save trees, ink, time, and to stick it to the bureaucrats, I wrote this script

I have, in the past but not recently, run into situations where I need to visually sign something, and the form was rejected when I digitally signed it with MacOS Preview because they required the form be printed, signed, and re-scanned.

This would be helpful in that case.

I knew that, and I do run macOS, but the signature always looks "digital" to me. It's not bad, but with Krita and it's pen or pencil brushes, in combination with a decent drawing tablet (well, as decent as a Huion screen tablet is) with a pressure-sensitive pen, I can get something that looks outright indistinguishable to a physical signature.
