I miss this sorely in Canada. For my Estonian dealings, I've been signing documents (any file for that matter) electronically since 2003. https://en.wikipedia.org/wiki/Estonian_identity_card Ontario was to introduce a digital identity system by 2021 but we are still waiting. I haven't looked into it, so I'm not sure if the plan is to also provide PKI. I saw some nut job at an intersection in Mississauga the other day holding a banner against digital identity in Canada.

I think signing a document is a solemn act. So I don't want to just paste a .PNG of my signature, I want to actually sign it.
I don't have a modern Linux device with a stylus. (Somewhere I have a ThinkPad x61 and a couple of Sharp Zaurus PDAs.)
I do have an iPad and a ThinkPad C13 ChromeBook, both of which have styli. In each case it is a little intricate so I thought others might find my methods useful. Suggestions welcome.
On the iPad:
- I can plug in the ipad to a USB port of my desktop and instruct the iPad to act like an external disk drive
- using Gnome Files, I can transfer the PDF to a directory on the iPad.
- using the file browser on the iPad, I navigate to the PDF, long press on it, and select "Quick View". I don't want Adobe tools.
- I can just write on the document with the stylus and save it. I usually save it with a different name, one that indicates that it is a signed document.
- using Gnome Files, I copy the signed document from the iPad to my desktop.
- Using Gnome Files, I "eject" the two removable filesystems that are the iPad's. I can then unplug the iPad
On the Chromebook:
- I have already installed the Linux subsystem. I start up the terminal in the Linux container.
- I use scp to copy the PDF from the desktop to ChromeBook's Linux filesystem (my home directory)
- I use the ChromeOS Files application to open the PDF file (the Linux container's filesystem is visible to Files).
- I tap a snake-like symbol on the top of the screen (It seems to signify scribbling).
- I write my signature
- I save the result, with a distinct name, in the Linux Container filesystem
- back in the terminal, I issue the scp with the arguments suitably adjusted (easy to type with bash's history mechanism).
I find the ChromeBook a bit easier. Partly because WiFi is easier than wiring (I have only one lightening cable and it is usually hooked up to a charger). If I found an iOS SCP application that might even the platforms. --- Post to this mailing list talk@gtalug.org Unsubscribe from this mailing list https://gtalug.org/mailman/listinfo/talk
