A certificate contains an identity, a public key, and signatures attesting that the public key belongs to the identity. Other fields that may be present include the organization (for example, university, company, or government) to which that identity belongs and perhaps suborganizations (college, department, program, branch, office). What security purpose do these other fields serve, if any?

Explain your answer.

What will be an ideal response?

Sometimes
these
other
fields
are
the
keys
to
establishing
trust.
For
instance,
my
use
case
may
cause
me
to
trust
anyone
with
a
valid
US
government
email
address,
and
having
that
email
address
be
part
of
a
certificate
may
be
sufficient
proof
as
long
as
I
trust
the
certificate
authority
that
issued
the
certificate
to
have
validated
that
information.
