You can securely manage the network device using a Web browser and the HTTPS protocol.
To authenticate the HP Jetdirect Web Server when HTTPS is used you may configure a certificate. Or you may use the pre-installed, self-signed X.509 Certificate.
The encryption strength specifies what ciphers the Web server will use for secure communications.
By enabling encryption, the Web Server encrypts all Web communication, forcing all connections to use HTTPS.
Or, it can be configured to allow both HTTP (unencrypted) or HTTPS connections.
In secure environments, you should choose to encrypt all Web communications.
Otherwise, sensitive management data (Administrator Password, SNMP Community Names, and secret keys) may be compromised.
