When you already have a digital certificate from a trusted authority, signing with existing certificates means you reuse that credential to authenticate documents or code without generating a new one. It's a common practice in environments where certificates are managed centrally, like corporate IT or software development teams. This saves time and ensures consistency, especially when renewing signatures or applying your digital identity across multiple files.
