A digital signature enables you to sign a PDF document just like you would sign a paper form and serves the same purpose: to identify you uniquely in writing. Adobe Acrobat Professional makes it easy to create your own digital signature to use when signing PDFs. If you do not have Adobe Acrobat Professional installed on your work computer or if you're unsure, please contact your Computing Coordinator.
By itself your self-signed signature does not uniquely identify you as there is nothing stopping another person from creating a self-signed signature with your name attached to it. However, your digital signature is unique once you've created it, and once it has been trusted by someone--i.e. they have verified that this particular signature does, in fact, belong to you--any other self-signed signatures bearing your name that did not come from you can easily be identified as forgeries. (For more information on how this magic works, I invite you to research Public Key Cryptography.) Usually this verification is done by a trusted third party, but in our case you will need to establish this trust relationship directly with the recipient of your signed PDF. There are a couple of ways to do this. The easiest way is to have the recipient trust your signature the first time they see it after they've verified that it came from you. The second method involves sending the recipient a certificate file that they can import into Acrobat ahead of time that tells Acrobat to trust your signature when it sees it. If you need to send a certificate, contact your Computing Coordinator for help.
