Using a Self-Signed Certificate
A self-signed certificate encrypts communications, but does not include a digital signature from a
commercial CA. It is free and easy to configure, but if you want to avoid having your users see an
untrusted site warning every time they use
groov , you must install the self-signed certificate in the
browser certificate store for every browser that will access groov . This type of certificate is a good
solution for a small set of groovs and a small set of client browsers that you can configure.
Follow these steps to create and install a self-signed certificate:
“Step 1: Create a Self-Signed Certificate and Private Key” on page 42
“Step 2: Add the Self-Signed Certificate to a Browser Trust Store on a Computer” on page 46
“Step 3: Install an SSL Certificate on Mobile Devices” on page 49
Step 1: Create a Self-Signed Certificate and Private Key
Follow the steps below to generate the following components required to configure self-signed
certificate SSL communication. The self-signed certificate is automatically installed on the
groov Box.
• Private Key : This must be kept secret and never shared. Keep a copy of it in a safe and secure
place. There is also a Public Key included in the signed certificate. You will not handle the
public key using groov Admin.
• Signed Certificate : Contains identification information, the public key, and a digital signature.
Identification information includes the server name and the name of the organization that
controls the server. The self-signed certificate is digitally signed by the Private Key to establish
authenticity. The Certificate is automatically installed on the
groov Box.
To generate a private key and self-signed certificate:
1. In groov Admin, select Networking > SSL Configuration.
2.
Click the Create certificate tab.
3.
Fill in the Create SSL key form as follows:
Server name : Enter the fully qualified domain name (or hostname ) of this groov Box that client
browsers will use to access groov . (See also, “Changing the Hostname, DNS Servers, or IPv4
Gateway” on page 23 .) The server name may contain letters a–z (case insensitive), digits 0–9, or
a hyphen (-). No other characters are allowed. The server name must not start with a hyphen.
For example, if the URL you will use to access groov in client browsers is
https://process1.acme.com , then you enter
process1.acme.com
If you have multiple groovs with fully qualified hostnames all with the same domain, another
option is to create a self-signed wildcard certificate. For example, if you have two groovs with
the hostnames groov1.foo.com and groov2.foo.com , you can create a certificate that has the
hostname *.foo.com . The same private key and certificate are then installed on all the groovs .
