User certificates

[giogi]

Certificates (CA and non-CA) can be loaded onto devices.
In addition, the device can generate a certificate to validate itself (device signature).
can you tell me how to create a user certificate to validate the user? And how to load it in the machine (canon device)
it is used in the send function to certify that a specific pdf has been sent by a specific user.
Users can install a digital signature that embeds their name and e-mail address to confirm their identity as the source of the document and provides notification if changes have been made.
In this way, the receiver is able to identify the user who signed the document.

thanks
