Sending Digitally Signed Messages
After you pick a provider for your Digital ID, you fill out a number of forms
and pick a password for the ID. You’ll also need to exchange several e-mails
with a Digital ID provider; that’s how you prove that your e-mail address is
really yours.
Sending Digitally Signed Messages
After you have a Digital ID, the simplest thing you can do is send someone
a message that has your digital signature. A digitally signed message does
more than simply assure your recipient that you’re really yourself — who
else would you want to be, after all? Suppose that you want to send a
scrambled (encrypted) message that only your recipient can read. To do so, you
have to send at least one digitally signed message first so that Outlook can
capture details about your Digital ID.
Sending a single message
After you have a Digital ID, you can send a message with a digital signature by
following these steps:
1. While creating a message, click the Options tab at the top of the
message screen.
The Options Ribbon appears.
2. Click the arrow next to More Options.
The Properties dialog box appears (as shown in Figure 15-2).
3. Click the Security Settings button.
The Security Properties dialog box appears.
4. Select the Add Digital Signature to This Message check box.
5. Click OK.
The Security Properties dialog box closes.
6. Click Close.
Your message is now secure.
