Digital signature certificates are a way to prove that a document has not been tampered with. They work by creating a digital signature for each person who signs the document, so that it cannot be forged or altered without the private key of that individual. The certificate itself is called an attestation, and can be used in conjunction with other security measures such as encryption and digital signatures.

Digital signature certificates provide three benefits:

They provide proof to anyone reading your email or PDF file that you were the source of those documents — not a third party who might have had access to them

They help protect your identity since only an authorized person can generate one from their own personal key pair (i.e., one which they control) and use it for signing other documents

They offer added security against tampering by making all changes visible on any copy of the document (i.e., if someone wants to change something about your signed message, he or she would first have to delete all copies before making new ones).
