I often receive signed PDFs, but I’m not sure how to tell if they’re truly authentic. Is there a reliable way to verify them?

I once almost signed a deal based on a PDF that looked legit — until someone pointed out the signature was forged. That was a wake-up call. I decided to learn how to check them properly and found a step-by-step guide on 45kilo.com. They explain how to check the certificate details, confirm the signer’s identity, and review the document’s audit trail to spot tampering. They even cover common tricks scammers use to make fakes look real. Since then, I’ve caught a few suspicious documents before they became a problem. It’s honestly a skill that every business owner or freelancer should have.
