Register a user's certificate used for encrypting E-mail message with S/MIME.
The following two methods are available for registering a user's certificate:
Registering a user's certificate as destination registration information when the E-mail address is registered on this machine.
Sending an E-mail attached with a digital signature (user's certificate) to this machine to register the certificate automatically in this machine using S/MIME function.
The following describes the method to send an E-mail attached with digital signature (user's certificate) to this machine for automatic registration.
Before registering the certificate, you must register on this machine the E-mail address of the user whose certificate you wish to register.
This machine must be able to receive E-mail messages.
In the administrator mode, select [Network] - [E-mail Setting] - [S/MIME], then configure the following settings.
Settings | Description | |
---|---|---|
[S/MIME Comm.Setting] | Select [ON] to use the S/MIME. To select [ON], the E-mail address of the certificate of this machine must match the E-mail address of the administrator. [OFF] is specified by default. | |
[Automatically Obtain Certificates] | To register digital signature (user's certificate), select [ON]. [OFF] is specified by default. | |
[Print S/MIME information] | Select whether to print the S/MIME information, if necessary. [OFF] is specified by default. | |
[Certificate Verification Level Settings] | To verify the certificate, select items to be verified. If you select [Confirm] at each item, the certificate is verified for each item. | |
[Validity Period] | Confirm whether the certificate is still valid. [Confirm] is specified by default. | |
[Key Usage] | Confirm whether the certificate is used according to the intended purpose approved by the certificate issuer. [Do Not Confirm] is specified by default. | |
[Chain] | Confirm whether there is a problem in the certificate chain (certificate path). The chain is validated by referencing the external certificates managed on this machine. [Do Not Confirm] is specified by default. | |
[Expiration Date Confirmation] | Confirm whether the certificate has expired. Confirm for expiration of the certificate in the following order.
[Do Not Confirm] is specified by default. |
Send the E-mail attached with digital signature from the computer to this machine.
