Https Setting - Mitsubishi Electric NZ2FTGN User Manual

HTTPS setting

This function provides encrypted communications in the transport layer between the Web server and client to ensure the
reliability of the Web server and the consistency and confidentiality of send data.
The HTTPS communications are set with the parameter "HTTPS setting" of the coupler.
HTTPS server and connection
When connecting to the Web server using HTTPS, specify the following URLs in the Web browser.
Coupler
NZ2FT-GN
NZ2FT-BT
NZ2FT-PN
NZ2FT-PBV
NZ2FT-MT
NZ2FT-EIP
*1 When the parameter "IP address USB port" of the coupler has been changed from the default, after resetting the coupler, specify the
changed IP address after "https://".
When encrypted communications are performed, authentication of certificates is performed. For the following cases, a
warning message may be displayed on the Web browser.
• When the certificate has a problem
• When the current certificate has been read
• When the IP address of the coupler has been changed
• When the certificate has been changed
In the case a warning message is displayed, allow unencrypted communications on the web browser to connect to the Web
server.
TLS/SSL certificates
The CA certificate subscribed by the credible authentication station (CA) can be set in the coupler. TLS (Transport Layer
Security) and SSL (Secure Socket Layer) are protocols for the secure communications between the Web server and Web
client.
The private key, server certificate, and CA certificate to be replaced are sent from the personal computer to the Web server.
Therefore, connect the personal computer to the USB port of the coupler when sending them.
Use OpenSSL or others to create a private key and the corresponding server certificate and CA certificate.
The Web server supports the following.
• Encryption by TLS 1.1 and TLS 1.2
• Key length up to 2048 bits
• PEM encode key and certificate (.pem)
