Certificate

Figure 6 - 30. Certificate Settings

The LARA eco uses the Secure Socket Layer (SSL) protocol for any encrypted network

traffic between itself and a connected client. During the connection establishment the

LARA eco has to expose its identity to a client using a cryptographic certificate. Upon

delivery this certificate and the underlying secret key is the same for all LARA eco ever

produced and certainly will not match the network configuration that will be applied to the

LARA eco by its user. The certificate’s underlying secret key is also used for securing the

SSL handshake. Hence, this is a security risk (but far better than no encryption at all).

However, it is possible to generate and install a new base64 x.509 certificate that is unique

for a particular LARA eco. In order to do that, the LARA eco is able to generate a new

cryptographic key and the associated Certificate Signing Request (CSR) that needs to be

certified by a certification authority (CA). A certification authority verifies that you are the

person who you claim you are and signs and issues a SSL certificate to you.

To create and install a SSL certificate for the LARA eco the following steps are necessary:

• Create a SSL Certificate Signing Request using the panel shown in Figure 6 - 30.

You need to fill out a number of fields that are explained below. Once this is done,

click on the button “Create” which will initiate the Certificate Signing Request

generation. The CSR can be downloaded to your administration machine with the

“Download CSR” button (see Figure 6 - 31).

• Send the saved CSR to a CA for certification. You will get the new certificate from

the CA after a more or less complicated traditional authentication process

(depending on the CA).

• Upload the certificate to the LARA eco using the “Upload” button as shown in

Figure 6 - 31.
