As more and more businesses adopt paperless processes, the adoption of e-signatures has taken off. But there is some confusion between the different technologies that are involved. A lot of people ask me about the differences between electronic signatures and digital signatures.

what is a digital signatureTo fully understand the topic, it’s important to understand what a digital signature is and how it works. Today I’ll give you a bird’s eye view of this complex technology. If you’d like to learn more about the nuts and bolts, feel free to contact us to find a time to talk about it with John Harris, our director of product management and in-house digital signature expert.

What is a Digital Signature?

A digital signature is a way to sign documents, but it's more than that. You’re probably already using digital signatures today. Ever see a lock icon or a green background in your browser’s address bar when you’re shopping online? That’s a digital signature too. That type of digital signature verifies a server or the content of a webpage.

When you sign a document online with digital signatures, the digital signature is used to verify that a signed document is authentic. Digital signatures can prove the identity of the person signing the document and can show whether the document has been tampered with since it was signed.

Digital signature technology has been used for decades, which means it's highly standardized and accepted. This is important because your documents need to be legally valid not just today but years down the road. Digital signature technology isn't some trend that will come and go, leaving your business wondering what to do next. Digital signatures are here to stay.

Because digital signatures are embedded into the documents and are based on industry and international standards, they can be verified independently. Digital signatures are also more widely accepted internationally than more simplistic types of electronic signatures.

How Do Digital Signatures Work?

To create a digital signature, the content of the document being signed is used to create a very long unique number called a hash. The hash code is unique to the document, and it records what the document looked like at the time of signing. Think of it like a fingerprint for the document.

The hash code is then encrypted using the signer’s private key (a code that only the signer can access), and the encrypted hash becomes the digital signature. The identity of the signer, the nature of the document when it was signed and the digital signature itself are permanently embedded into the document.

The signer’s digital certificate works alongside the digital signatures. The digital certificate is a public version of the signer’s private key, and third parties can use it to verify the signatures and the identity of the signer. This provides evidence in case a signer tries to argue, "Those terms weren't in the document when I signed it."
