Setting Up Thunderbird to Use Signing and Encryption Certificates
Operating System: Mac OS X, Windows
From the Tools menu, select Account Settings.
Select the Security option for the account associated with the certificate.
In the Certificates area, click View Certificates.
If no certificates display, click Import and browse for the files. Locate your signing certificate file. You can also download it from the Stache web page.
When you select the file, Thunderbird prompts you for your Software Security Device password. If you do not have one for Thunderbird, you can create it now.
Note: Although Thunderbird uses the same terminology as Firefox, the passwords are separate and must be created for each application.
When prompted, enter your password set for exporting your certificate. The password is provided via the Stache web page.
Repeat steps 3-6 for any additional certificates.
Click OK until you have closed all the dialog boxes.
Note: You can send an encrypted message only if you have the recipient's public key. If you do not, Thunderbird displays an error message. You then have the choice to cancel sending or to send unencrypted.
