Digital Signature is a process that guarantees that the contents of a message have not been altered in transit.
When you, the server, digitally sign a document, you add a one-way hash (encryption) of the message content using your public and private key pair.
Your client can still read it, but the process creates a "signature" that only the server's public key can decrypt. The client, using the server's public key, can then validate the sender as well as the integrity of message contents.
