Select the signature algorithm from the drop-down list.
Select the key generation algorithm from [RSA] or [ECDSA], then select the key length from the drop-
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 [Signature Algorithm], [512-bit] cannot be selected as the
key length when [RSA] is selected in [Key Algorithm].
