If the parameter ``binary_form`` is :const:`False`, and a certificate was
received from the peer, this method returns a :class:`dict` instance. If the
certificate was not validated, the dict is empty. If the certificate was
validated, it returns a dict with the keys ``subject`` (the principal for
which the certificate was issued), and ``notAfter`` (the time after which the
certificate should not be trusted). If a certificate contains an instance
of the *Subject Alternative Name* extension (see :rfc:`3280`), there will
also be a ``subjectAltName`` key in the dictionary.
validated, it returns a dict with several keys, amongst them ``subject``
(the principal for which the certificate was issued) and ``issuer``
(the principal issuing the certificate). If a certificate contains an
instance of the *Subject Alternative Name* extension (see :rfc:`3280`),
there will also be a ``subjectAltName`` key in the dictionary.
The "subject" field is a tuple containing the sequence of relative
distinguished names (RDNs) given in the certificate's data structure for the
principal, and each RDN is a sequence of name-value pairs::
The ``subject`` and ``issuer`` fields are tuples containing the sequence
of relative distinguished names (RDNs) given in the certificate's data
structure for the respective fields, and each RDN is a sequence of
name-value pairs. Here is a real-world example::
{'notAfter': 'Feb 16 16:54:50 2013 GMT',
'subject': ((('countryName', 'US'),),
(('stateOrProvinceName', 'Delaware'),),
(('localityName', 'Wilmington'),),
(('organizationName', 'Python Software Foundation'),),

(('commonName', 'somemachine.python.org'),))}
{'issuer': ((('countryName', 'IL'),),

(('organizationalUnitName',
'Secure Digital Certificate Signing'),),
(('commonName',
'StartCom Class 2 Primary Intermediate Server CA'),)),

.. note::
To validate a certificate for a particular service, you can use the
:func:`match_hostname` function.
If the ``binary_form`` parameter is :const:`True`, and a certificate was
provided, this method returns the DER-encoded form of the entire certificate
