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.
