2.11 Sending scan data by E-mail (Public key-based encryption)
% Specify settings for sending scan data as a message encrypted by public keys.
When scan data is sent by E-mail, the scan data can be sent by encrypting it using the user certificate
registered in this machine in advance.
Sending encrypted messages prevents disclosure of information to third parties on the transmission path. In
addition, if the message is encrypted by attaching the digital signature, authentication of this machine and
message is possible.
