Note that just because one signer is using a digital signature does not mean … Similarly, digital signatures are used to authenticate the contents of electronic documents. When you sign a physical document, you are authenticating its contents. The property of non-repudiation is achieved by using a digital signature. Because a digital signature is effectively, ‘wrapped up’ in the content of the document, it means that if anyone tries to change anything about that document content, the signature will also change.
