Creating a CA certificate
1. Generate a self-signed certificate CA:
openssl req – new -x509 -days 3650 -key cambium-ca.key -out cambium-ca.crt
2. Enter pass phrase for cambium.key:
You are asked to enter information that will be incorporated into your certificate request.
What you enter is called a
Distinguished Name or a DN . There are quite a few fields of which
you can leave some blank. For some fields there is a default value,
If you enter '.', field is left blank.
-----
Country Name (2 letter country code)
State or Province Name (full name)
Locality Name (Ex. City)
Organization Name (Ex, Cambium Networks)
Organizational Unit Name (Ex. Cambium)
Common Name (Ex. cambium root CA)
Email Address (Ex.
admin@cambium.com)
3. Generating the certificate, you must enter a passphrase, with a closed key CA, and then - to
fill in the required fields (company name, email, etc.); the most important of these is the
Common Name - the unique name of the certification center.
In this case, as the Common name was chosen "cambium root CA", view the resulting
certificate command as shown below:
openssl x509 – noout – text -in cambium-ca.crt
As a result, we see:
