What is a Digital Signature?

Digital signatures are the online equivalent of a notarized signature. To apply Digital Signatures to messages and files the organization must hold a valid digital certificate. Digital certificates are issued by GlobalSign. We are a trusted Certificate Authority and we maintain one of the world's largest and most trusted Public Key Infrastructures (PKI).   

When you apply a digital signature, a cryptographic operation binds your digital certificate and the data being signed (in this case, a PDF or Microsoft Office document) into one unique fingerprint. The uniqueness of the two components of the signature are what makes digital signatures a viable replacement to wet ink signatures.

Digital Signatures provide:

  • Authentication – since your third-party validated certificate was used to apply the signature, recipients know it was actually you who signed it 

  • Message integrity – when the signature is verified, it checks that the data in the document matches what was in there when the signature was applied. Even the slightest change to the original document would cause this check to fail.
