Registered & Encrypted™: If the sender and recipient have exchanged their standard public key digital certificates, the sender may send their e-mail such that the recipient is aware sender has verifiable proof of content and official time sent and received, as well as ensure that no party other than the recipient can view the content of that e-mail.

Registered & Signed™: If the sender has a standard public key digital certificate, the sender may send their e-mail such that the recipient can verify sender authenticity and e-mail integrity, in addition to the Registered E-mail® functionality.
