Keys Stored on Smart Cards

If the private-public key pair, with its certificate, is stored on a smart card, a card reader must be properly attached to the mail user’s computer. The card reading device also requires software; the device and its software are supplied by the vendor from whom you purchase this equipment.

When properly installed, a mail user inserts their smart card into the reading device when they want to create a digital signature for an outgoing message. After verification of their smart card password, the private key is accessible by Communications Express Mail to sign the message. See Required Software and Hardware Components for information on supported smart cards and reading devices.

Libraries from the vendor of the smart card are required on the user’s computer. See Key Access Libraries for the Client Machines for more information.
