How to Use a Smart Card for Secure E-Mail and Digital Signatures

Before you can receive encrypted e-mail or send digitally signed e-mail, you must first configure Outlook or other e-mail application to use your smart card's digital certificates. Publishing your certificates to the NIH Global Address List (GAL) simplifies the exchange of encrypted e-mail within NIH.

However, you may still need to publish your certificate to the GAL.

Reading Old Encrypted Email

If you are unable to read old encrypted email, you need to obtain copies of your prior email encryption digital certificates and associated private keys. You can obtain these items from the HHSIdentity PIV Portal. Please see the instructions for recovering and installing encryption certificates for more information.

If you are having problems with sending encrypted email please see Solving Outlook Encryption Problems.
