Certificate Authority Chain, can be also referred to as CA bundle, is a set of intermediate
and root certificates used to establish the connection between a certificate issued for a domain name
(end-entity certificate) and a Certificate Authority root that issued the certificate.
The end-entity certificate is signed by the intermediate certificate (subordinate CA),
which in its turn is signed by a root certificate, or another intermediate certificate signed by root.
Root certificates are generated by Certificate Authorities. They are embedded into the
software applications, browsers and operating systems and their installation on the server
is not mandatory in most cases. Your web browsers will automatically trust the certificate
if they succeed to track the chain of trust to the root certificate. The root certificate is a
starting point in this chain of trust and is considered a trust anchor.
Root certificates sign intermediate certificates. The latter ones serve as a link between
the Certificate Authority and the website certificate. When a user browses to the website
protected by the SSL certificate via secure connection, the browser initiates the verification
of the certificate and follows the chain of trust up to the root certificate embedded in it.
Intermediate certificates should be installed on the server, along with the end-entity certificate,
for the certificate to be recognized as a trusted one in all browsers.
* Without the Installation of the intermediate CA certificate your SSL certificate may have trust
issues on certain applications, although majority of browsers have the capability of fixing this on their own.
