I would like to copy an ssh key to my Android phone. However, I have displaced the connection cable for my computer. I am looking for a safe way to transfer the key to the device.
Obviously, I don't want to send it to my device using email (attack vectors everywhere). Using bluetooth is not an option since my laptop doesn't support it. I could transfer the key safely to my server via SSH and then copy it back using Password authentification, but I feel like there must be a "cleaner" way of doing this that doesn't involve broadcasting the keys into the internet in some form.
