Managing Servers with Netscape Console • December 2001

Certificate Chains

CA hierarchies are reflected in certificate chains. A 

certificate chain

 is series of 

certificates issued by successive CAs. Figure B-7 shows a certificate chain leading 
from a certificate that identifies some entity through two subordinate CA 
certificates to the CA certificate for the root CA (based on the CA hierarchy shown 
in Figure B-6).

Figure  B-7

Example of a Certificate Chain 

A certificate chain traces a path of certificates from a branch in the hierarchy to the 
root of the hierarchy. In a certificate chain, the following occur:

•

Each certificate is followed by the certificate of its issuer.

•

Each certificate contains the name (DN) of that certificate’s issuer, which is the 
same as the subject name of the next certificate in the chain.
