title: Digital Signature: Certificate of a Signer using SignServer Java
body: <p>I have a requirement to create digital signature on behalf of client using SignServer. I am a little bit confused regarding 2 issues.</p>
  
  <ol>
  <li>Does every client requires a unique certificate or can a single certificate be used for all?</li>
  <li>Can I create digital signature certificates using SignServer because I can't find anything like that in their documents. If No, what is the suggested way to create digital signature certificates from a server side application?</li>
  </ol>
  
  <p>Thanks in Advance</p>
