Chapter 17. Collaborating on Documents > Adding a Digital Signature

Adding a Digital Signature

Digital signatures are a new feature in WordPerfect 10. You can add a digital signature to a document, which guarantees that it has not been altered since you signed it, and that you are actually the person who prepared the document. For example, if you collaborate on sensitive documents and use e-mail to send the file to others, it’s particularly important that you be able to prove that you are the person who has sent it and that no one else has modified the document since you signed it. Think of it as an electronic driver’s license or passport.

Digital signatures are used to authenticate the identity of individuals who are exchanging information across the Internet. Through the magic of asymmetric cryptography, two keys can be created—one is the public key and the other is the private key. The public key can be used to verify the private key, but it cannot be used to identify the private key. As long as the private key remains confidential, the identity cannot be forged.
