Digital Signatures VS Electronic And Wet Signatures: What’s The Difference?
Wait, first, before we begin - Do you know the difference between digital, electronic, and wet signatures?
Imagine if someone emails you a PDF document where they need your signature.
Now, you could print it out, sign it, and send it back as an email attachment. But let’s face it, that’d be too inconvenient and time-consuming.
And when you’re adding your signature to the PDF document, you’ll also want to know which kind to add first.
So, let’s take a look at the differences between digital, electronic, and wet signatures first.
Digital and electronic signatures are often used interchangeably, but they're actually different.
Notably, electronic signatures include all forms of a signature block, while digital signatures are attached to an actual signature.
An electronic signature is equivalent to your handwritten signature. Therefore, it has a higher authority. It is an image of your written signature that is overlaid in a PDF document.
On the other hand, a digital signature is cryptographically secure. This means that someone with your specific sign-in/login details will be able to enter a PDF document if they have these.
Digital signatures are equivalent to notarized signatures. Therefore a trusted third party will serve as the notary and identify your identity/verification.
Here are the key differences between the different types of PDF signature blocks:
- Digital signatures are used to secure a PDF document. They’re regulated by the certification authority.
- Electronic signatures (e-signature) are used to verify PDF documents. Usually authorized by specific vendors, document creators, or participating parties.
- Wet signatures is embedded onto a document by hand and has no digital uses. In other words, this means printing out a document and signing it yourself by hand. In most cases, very inconvenient.
