Sending Secure Emails

You can use your smart card-based certificate to read and send digitally signed and encrypted emails.

  • Encrypting an email message guarantees that only the intended recipient can open and read the message and its attachments.
  • Adding your digital signature to an email authenticates you as the sender and verifies the integrity of the message.
