Digital signatures are electronic versions of your handwritten signature—a way to prove you approved or sent a document without printing it out and signing by hand. They use encryption technology to attach your identity to a file in a way that's difficult to forge. You might encounter digital signatures when signing contracts online, approving loan documents, or authorizing medical records. Understanding how they work and when they're legally valid helps you recognize when you're actually signing something important versus when a straightforward typed name will do.

The articles here explain what happens behind the scenes when you digitally sign a document, how to spot a legitimate digital signature request, and which situations require a real digital signature versus which ones don't. You'll learn what makes a digital signature different from just typing your name, how to use common tools to sign documents, and what to watch for to avoid scams that pretend to be official signing requests.
