While working with a Web site, you might need to digitally sign some information before sending it to the Web site. Your digital signature guarantees the validity of the information you send to the Web site.

For example, you might purchase a product from the Web site, and your digital signature proves to the Web site that you requested the product. Your signature prevents you from denying that you requested the information, must and your written signature on an invoice proves your request for a product. You might also need to digitally sign information to guarantee its accuracy, such as a change in your mailing address or other account information.

1. Enter information on the Web site and click a button that triggers the signing process. The button might be labeled something like Sign or Confirm or Enter.
