6.5.6 What’s a Certificate Chain
Certificates (see section “What’s a Certificate”) can be distributed in a
chain, where the last certificate (the leaf certificate that cannot create
other certificates) certifies that it comes from another certificate (the in-
termediate certificate), this certifying that it comes from a further cer-
tificate (another intermediate), and so on until the last certificate in the
chain is reached (the root certificate that confirms the validity of the
whole chain as well as the identity of its issuer).
The whole structure of a certificate chain implies a hierarchy where the
highest rank is held by the root and the lowest by the leafs.
