Encrypting a Message with Outlook 2000

E-mail messages are relatively easy to intercept and read. With Outlook 2000, you can encrypt your e-mail messages so that only the intended recipients can read them.

To encrypt a message, you must have a copy of the intended recipient's certificate. The easiest way to get a copy of someone's certificate is to have them send you a signed message. When you receive a signed message, you can store the sender's certificate in your address book. For more information about storing certificates in your address book, see Adding a Certificate to Your Address Book.

The Encrypted icon indicates that a message has been encrypted. When you receive an encrypted message, Outlook 2000 automatically unencrypts the message and displays the Encrypted icon when the message is viewed.

You can encrypt individual messages or configure your e-mail security options to automatically encrypt all e-mail messages to recipients whose certificates are stored in your address book. For information on selecting the certificate to use when encrypting messages, see Choosing a Default Certificate for Signing and Encrypting Messages.



Encrypting a Message with Eudora Pro

E-mail messages are relatively easy to intercept and read. With Eudora Pro 4.1 and the S/MIME plug-in WorldSecure Client 3.0, you can encrypt your e-mail messages so that only the intended recipients can read them.

To encrypt a message, you must have a copy of the intended recipient's certificate. The easiest way to get a copy of someone's certificate is to have them send you a signed message. When you receive a signed message, you can store the sender's certificate in your address book. For more information about storing certificates in your address book, see Adding a Certificate to Your Address Book.

Encrypting Individual Outgoing Messages


Retrieving in Internet Explorer without cookie

If you are running Internet Explorer and the IdenTrust cookie is not detected (i.e., the DST Root CA X1 is not in the browser), then you must install the root certificate and then the certificate chain (which consists of the S/MIME certificate and the sub-CA certificates). To retrieve the required certificates in this scenario, complete the following steps:
  1 Go to the URL specified in the letter you received upon approval - this URL is Certificate Issuance page.
  2 Enter the Activation Code provided in the letter.
  3 Enter the Passphrase you specified when you applied for the certificate in the Your Passphrase field, and then Click Retrieve. The Certificate Retrieval Instructions appear.
  4 Print the instructions by Clicking the Print button in your browser's toolbar.
  5 Click the link that says "Retrieve your Certificate." A message appears that asks, "Do you want to ADD the following certificate to the Root Store?"
Note: If this message does not appear, the root certificate has already been installed. Skip to step 7
  6 Click Yes. The Status Screen appears and displays information about the certificate.
  7 Click Continue. The retrieval process is complete.

You have now successfully installed your digital certificate to your Internet Explorer browser. Your computer is now capable of sending digitally signed messages to others.
