This documentation is provided for LBL approved Entrust Users (of whom there are only a few). LBL approved encryption products are described here.

Read and Send Entrust Mail In the Default LBNL Configuration:

1. Receive an email in Thunderbird.  It does not show an attachment but you believe it is entrust encrypted. You cannot open the entrust entachment from within Thunderbird (as of this release of both programs). So...

2. Open LBL Webmail http://www.lbl.gov/mail

Now you can see the Attachment.  Click on the Attachment.

Firefox will ask how you want to open the attachment; if you have Entrust installed correctly, the default option will be “Entrust/ICE Right Mouse”.

Entrust should now prompt you for your credentials, and you should be able to open the document.

Sending in Entrust in the LBL Configuration:

Because we use Thunderbird, you cannot directly encrypt an email using Entrust either (do you see why it's not supported here?).  Instead, you should encrypt the attachment itself, then attach it to an email.

Find the attachment you wish to send in the Windows File Manager (Explorer).  Right click, choose “Secure for List” then “Select Recipients”

Names will appear on the left hand side (if they match).

Choose Add> to add them to the selected recipients list, then click OK (remember, an encrypted file in Entrust can only be opened by its defined recipients, so if you want to make it readable to Jane Doe and Bob Flow, they both need to be on the list.)

Now, the file should show up as a .p7m file instead of whatever it was before with a key logo on it.  You can then attach that file to an email and send it as you would any other attachment in Thunderbird.
