Digital Signatures Articles

Digital signatures are a way to verify that a document or message actually came from who it claims to come from, and that it hasn't been altered since it was signed. They work differently than handwritten signatures—they use cryptography to create a unique fingerprint tied to both the document and the person who signed it. You encounter digital signatures when you sign tax forms online, approve bank transfers, or verify software downloads.

The articles here explain how digital signatures actually work, why they matter for your security, and where you're likely to use them. You'll learn what makes a digital signature different from a scanned handwritten one, how to spot a legitimate signature versus a forged one, and what to do if you need to sign something digitally yourself.
