down list. In either case, the larger the number for the key length is, the higher the security level
becomes. However, the communication speed becomes slower.
● When [SHA384] or [SHA512] is selected in [Signatur
e Algorithm], [512-bit] cannot be selected as the
key length when [RSA] is selected in [Key Algorithm].
