Using digital signatures (part 2 of 2)

Make sure that you have imported your certificates into the Windows Certificate store [see https://ebraiter.wordpress.com/2013/03/14/using-digital-signatures-part-1-of-2/].

Outlook

In Outlook, from the File menu, click the Options menu, select the Trust Center section and click the Trust Center Settings button.

Click E-mail Security section and select the following options:

  • Add Digital Signature to Outgoing Messages: This option includes your signing certificate on all outgoing messages.
  • Send clear text signed messages when sending signed messages: This ensures that recipients can read your signed messages. It is especially important if your recipient is using a Web-based or mobile mail client.
  • For encryption, it is recommended that you do not select the option to “Encrypt contents and attachments for outgoing messages.” Instead, you manually choose encryption for individual messages rather than setting it by default.

Click on the Settings button. Outlook displays options for your signing and public encryption certificates under Certificates and Algorithms. Outlook includes your public signing certificate when it sends your signing certificate so that other users may send you encrypted messages. Click the Choose button to the right of Signing Certificate and select your certificate you previously imported from the list, and click the OK button. Select Hash Algorithm SHA1 [if not already].

Click the Choose button to the right of Encryption Certificate, select your certificate from the list, and click the OK button. Select Encryption Algorithm 3DES or AES 256-BIT [if not already]. Click the OK button again.

You should send an email to yourself as a test. Delivered messages will display the signing icon, encryption icon, or both, depending on the options you have selected in the Email.

Note: Other versions of Outlook may vary in the procedure.

Click on the Ad ID button. Under My existing digital ID from:, select A file. Locate the certificate and add the password from TrustCenter. Click on the Next button. The certificate will appear. Click on the Finish button. Now you can use the signing tool to digitally sign a PDF.
