How to Get a digital ID


A digital ID enables you to send cryptographic e-mail messages for more secure communication using Microsoft Office Outlook 2007. You can send digitally signed messages to prove your identity and prevent message tampering. You can also encrypt messages to keep your messages private. But first, you must obtain a digital ID from a reliable source.
