Oh my goodness, I have dealt with a pedantic bureaucrat who rejected my signed PDF and insisted on the hand signature hahaha. So I printed the document out with my digital signature pasted twice, one below the other, and added a couple sharpie smudges to the bottom one before scanning to quietly “insist back” that there’s no difference between my manual and digital one. Regardless, The automaton was satisfied!

#43Don't know about different Jurisdictions, but from where I am - this has NO legal binding whatsoever. We have those gov issued digital, invisible signatures for that, embedded in our personal ID card. Whatever is properly signed with digital signature, the printed out page bears no legal force. Anyway, businesses still like to do it this way ("Signing" pdf by applying some pixels). I wonder if it is just an inconveni…
Same over here! Only difference is that with our IDs/certs you usually have a visible cert block on the PDFs. You can get it to be invisible somehow, but that's a bit of a hassle.
But yes, anything that's not a proper digital signature might as well just be a random png pasted into a pdf. No legal binding power whatsoever.

#44Preview 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.
Same. You don't need a camera, you can doodle a signature with a mouse and it's fine. I bought a house this way with no trouble.
It's funny to me to look at a company like DocuSign whose shares surged early on the in the pandemic because they expected a dramatic increase in need for digital signatures and then the price crashed when it turns out that signatures aren't actually useful and we can just live without them.

#45I still miss a coffee stain.
it could use a --coffee-stain

#46Signature_example.pdf in that repository is NSFW.
If that signature is NSFW, you might want to consider W'ing for another company instead.

#47What'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.
The primary use case is addressing situations where wet ink signatures are required by a party to a transaction without having to print, sign, and scan a document.
Yes, it is an odd combination of legacy (sometimes regulatory) requirements and modern technology, but there are numerous situations where only wet ink signatures are accepted, and “digital signatures” are not accepted—even though the document is stored in a digital format.
Wet ink signatures are most commonly required in finance / investment / banking transactions. They are sometimes required for B2B transactions. While not as common in the US as in other countries, you can also run into requirements where documents must be signed via wet ink signature under seal (or stamp). Scanning a document with a signature line that has been embossed with a company seal looks somewhat comical and arguably legible (especially if the scan is done with a feed-through scanner) but is required to get business done sometimes.

I'm in the US and as far as I know, a digital signature is completely valid. [edit: ~it's the same way here.~ Misinterpreted parent comment.]
Yet Ford repeatedly insisted I print out the documents, sign them, and scan them. I tried a digital signature anyway - and they called me out on it.

#49I just use convert from imagemagick. There are so may options, e.g.: convert -density 100 -blur 0x0.1 +noise Gaussian -colorspace gray -rotate 0.5 -attenuate 0.2 mypdf.pdf scan.pdf
That's basically what this is doing to fake the scan: https://gitlab.com/edouardklein/falsisign/-/blob/master/fals...
> convert -density "${DENSITY}" "${PAGE_IN}" -linear-stretch 3.5%x10% -blur 0x0.5 -attenuate 0.25 -rotate "${ROTATION}" +noise Gaussian "${TMPDIR}/${PAGE_BN}-scanned.pdf"

#50Having 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. https://www.handy-signatur.at/hs2/#!sign/single When I tried sending such a document to a German insurance company, they refused to accept it. I ended up faxing the document :/
Usually sending them the following helps them be less stubborn:
> Gemäß Artikel 25 eIDAS-Verordnung hat eine qualifizierte elektronische Signatur die gleiche Rechtswirkung wie eine handschriftliche Unterschriftund wird in allen Mitgliedstaaten anerkannt.
Doesn't work always, but the times it doesn't I usually find a competitor that does prove to be more cooperative pretty easily!
