Outlook: Secure your email by using a free digital signature
아티클
Secure your email by using a digital signature is an option to make your email more secure. A digital signature isn't the same as a signature you routinely include with an outgoing message. Anyone can copy an email signature, which essentially is a customisable closing salutation. But your digital signature, which includes your certificate and public key, originates from your digital ID. And that digital ID serves as your unique digital mark and signals the recipient that the content hasn't been altered in transit. It seems like a complicated task to make this happens, but it is very easy to setup with the following steps:
There will be a pop-up windows dialog box, Web Access Confirmation, asks your permission to let the website perform a digital certification operation on your behalf.
You will see a confirmation page as below. Now is time to go to your mailbox, check an email from Comodo and get the digital certification to your email address.
From the welcome email from Comodo, you will have all information you need to download/get your digital certification. The following picture demonstrates how to get the cert file.
From the Trust Center dialog box, click Email Security from the left panel.
On the right/main panel, select Add digital signature to outgoing messages check box.
Optional: If you want to verify that your digitally signed message was received unaltered by the intended recipients, select the Request S/MIME receipt for all S/MIME signed messages check box
Click Settings button to open the** Change Security Settings** dialog box
Now is time to send your email securely. From the New email windows box, click Options tab. In the Permission section, make sure the Sign button is selected.
