What is a Certificate Chain
If you are familiar with a certificate chain, you can ignore this topic
and refer to
Illustration - GMAIL SMTP Certificate Chain
(on page
A certificate or a chain of certificates is used for trusting a TLS server
that you want to connect.
The receiver, such as PX3, can trust a TLS server only after an
appropriate certificate (chain) which is "related to" that TLS server's
certificate is uploaded to the receiver.
How a certificate chain is generated:
To explain how a TLS server's certificate is "related to" the certificate
(chain) that is uploaded to the receiver, we assume that there are three
"related" certificates.
Certificate C. The certificate issued to the TLS server you want to
connect.
'Certificate C' is issued by the certificate authority (CA) entity called
'Issuer B'.
Certificate B. The certificate issued to 'Issuer B'.
'Certificate B' is issued by a CA entity called 'Issuer A', and it is an
intermediate certificate.
Certificate A. The self-signed certificate issued by Issuer A. Issuer A
is a root CA.
The above three certificates form a certificate path, which is called the
"certificate chain".
