10.7 Loading Certificate Chain for Trusted Root
A certificate chain is a sequence of certificates where each certificate in the chain is signed
by the subsequent certificate. The last certificate in the list of certificates is the Root CA
certificate, which is self-signed. The purpose of a certificate chain is to establish a chain of
trust from a child certificate to the trusted root CA certificate. The CA vouches for the
identity of the child certificate by signing it. A client certificate is considered trusted if one of
the CA certificates up the certificate chain is found in the server certificate directory.
Figure 10-6: Certificate Chain Hierarchy
For the device to trust a whole chain of certificates, you need to combine the certificates
into one text file (using a text editor). Once done, upload the file using the 'Trusted Root
Certificate Store' field in the Certificates page.
Notes: The maximum supported size of the combined file of trusted chain of
certificates is 100,000 bytes (including the certificate's headers).
