When using Visual Studio Code in Windows, a lot of times you might want to connect to a remote server via SSH, so you can edit files on that server directly, instead of setting up a local development environment or pulling and pushing files repeatedly, e.g. via FTP.

Adding a digital signature to a PDF file is relatively easy using a library such as TCPDF, as long as your personal certificate is stored somewhere on your server/computer.
