Regarding my last video: yes, digitally signing a PDF with a certificate is more secure. Yes, it’s used by companies, but:
- they generally use third party tools
- At the 4 companies I worked at, we NEVER used such a system to sign a contract
- Most normal users just need to stamp their hand drawn signature and send the PDF back to avoid having to print it, sign it, scan it, and send it back
It’s definitely something all PDF tools should have by default, even if it’s not “secure”

@thelinuxEXP I worked at all kinds of companies, small (4 ppl) to multinational with 250.000 and everything in between from automotive to construction to FMCG. Dealing with customers from Austria, Germany, Switzerland, the Netherlands, UK, Scandinavia, US or Asia. I was an account manager and had to deal with contracts all the time. Not once did I encounter certificate signed PDFs in those environments. Most just printed, signed and scanned.

The only area I saw this was in (local) governments.

@rraggl Yeah, the only place Insaw them being used was when I worked at a company that produces software for realtors, and it was an option that let them send digitally signed documents to their clients for the purchase of a home.
