+The ssl.match_hostname() function from Python 3.2
+=================================================
+
+The Secure Sockets layer is only actually *secure*
+if you check the hostname in the certificate returned
+by the server to which you are connecting,
+and verify that it matches to hostname
+that you are trying to reach.
+
+But the matching logic, defined in `RFC2818`_,
+can be a bit tricky to implement on your own.
+So the ``ssl`` package in the Standard Library of Python 3.2
+now includes a ``match_hostname()`` function
+for performing this check instead of requiring every application
+to implement the check separately.
+
+This backport brings ``match_hostname()`` to users
+of earlier versions of Python.
+Simply make this distribution a dependency of your package,
+and then use it like this::
+
+    from backports.ssl_match_hostname import match_hostname, CertificateError
+    ...
+    sslsock = ssl.wrap_socket(sock, ssl_version=ssl.PROTOCOL_SSLv3,
+                              cert_reqs=ssl.CERT_REQUIRED, ca_certs=...)
+    try:
+        match_hostname(sslsock.getpeercert(), hostname)
+    except CertificateError, ce:
+        ...
+
+Note that the ``ssl`` module is only included in the Standard Library
+for Python 2.6 and later;
+users of Python 2.5 or earlier versions
+will also need to install the ``ssl`` distribution
+from the Python Package Index to use code like that shown above.
+
+Brandon Craig Rhodes is merely the packager of this distribution;
+the actual code inside comes verbatim from Python 3.2.
