Object types: SSLSocket -- subtype of socket.socket which does SSL over the socket Exceptions: SSLError -- exception raised for I/O errors Functions: cert_time_to_seconds -- convert time string used for certificate notBefore and notAfter functions to integer seconds past the Epoch (the time values returned from time.time()) fetch_server_certificate (HOST, PORT) -- fetch the certificate provided by the server running on HOST at port PORT. No validation of the certificate is performed. Integer constants: SSL_ERROR_ZERO_RETURN SSL_ERROR_WANT_READ SSL_ERROR_WANT_WRITE SSL_ERROR_WANT_X509_LOOKUP SSL_ERROR_SYSCALL SSL_ERROR_SSL SSL_ERROR_WANT_CONNECT SSL_ERROR_EOF SSL_ERROR_INVALID_ERROR_CODE The following group define certificate requirements that one side is allowing/requiring from the other side: CERT_NONE - no certificates from the other side are required (or will be looked at if provided) CERT_OPTIONAL - certificates are not required, but if provided will be validated, and if validation fails, the connection will also fail CERT_REQUIRED - certificates are required, and will be validated, and if validation fails, the connection will also fail The following constants identify various SSL protocol variants: PROTOCOL_SSLv2 PROTOCOL_SSLv3 PROTOCOL_SSLv23 PROTOCOL_TLS PROTOCOL_TLSv1 PROTOCOL_TLSv1_1 PROTOCOL_TLSv1_2 The following constants identify various SSL alert message descriptions as per http://www.iana.org/assignments/tls-parameters/tls-parameters.xml#tls-parameters-6 ALERT_DESCRIPTION_CLOSE_NOTIFY ALERT_DESCRIPTION_UNEXPECTED_MESSAGE ALERT_DESCRIPTION_BAD_RECORD_MAC ALERT_DESCRIPTION_RECORD_OVERFLOW ALERT_DESCRIPTION_DECOMPRESSION_FAILURE ALERT_DESCRIPTION_HANDSHAKE_FAILURE ALERT_DESCRIPTION_BAD_CERTIFICATE ALERT_DESCRIPTION_UNSUPPORTED_CERTIFICATE ALERT_DESCRIPTION_CERTIFICATE_REVOKED ALERT_DESCRIPTION_CERTIFICATE_EXPIRED ALERT_DESCRIPTION_CERTIFICATE_UNKNOWN ALERT_DESCRIPTION_ILLEGAL_PARAMETER ALERT_DESCRIPTION_UNKNOWN_CA ALERT_DESCRIPTION_ACCESS_DENIED ALERT_DESCRIPTION_DECODE_ERROR ALERT_DESCRIPTION_DECRYPT_ERROR ALERT_DESCRIPTION_PROTOCOL_VERSION ALERT_DESCRIPTION_INSUFFICIENT_SECURITY ALERT_DESCRIPTION_INTERNAL_ERROR ALERT_DESCRIPTION_USER_CANCELLED ALERT_DESCRIPTION_NO_RENEGOTIATION ALERT_DESCRIPTION_UNSUPPORTED_EXTENSION ALERT_DESCRIPTION_CERTIFICATE_UNOBTAINABLE ALERT_DESCRIPTION_UNRECOGNIZED_NAME ALERT_DESCRIPTION_BAD_CERTIFICATE_STATUS_RESPONSE ALERT_DESCRIPTION_BAD_CERTIFICATE_HASH_VALUE ALERT_DESCRIPTION_UNKNOWN_PSK_IDENTITY i����N( t namedtuple( t closing( t OPENSSL_VERSION_NUMBERt OPENSSL_VERSION_INFOt OPENSSL_VERSION( t _SSLContext( t SSLErrort SSLZeroReturnErrort SSLWantReadErrort SSLWantWriteErrort SSLSyscallErrort SSLEOFError( t CERT_NONEt CERT_OPTIONALt CERT_REQUIRED( t txt2objt nid2obj( t RAND_statust RAND_add( t RAND_egdc C sC x< t t � D]. } | j | � r t t | � t � | <q q Wd S( N( t dirt _sslt startswitht getattrt globals( t prefixt n( ( s /usr/lib64/python2.7/ssl.pyt _import_symbolss s t OP_t ALERT_DESCRIPTION_t SSL_ERROR_t PROTOCOL_t VERIFY_( t HAS_SNIt HAS_ECDHt HAS_NPNt HAS_ALPNt HAS_TLSv1_3( t _OPENSSL_API_VERSIONc C s: i | ]0 \ } } | j d � r | d k r | | � q S( R t PROTOCOL_SSLv23( R ( t .0t namet value( ( s /usr/lib64/python2.7/ssl.pys <dictcomp>� s ( t sockett _fileobjectt _delegate_methodst errort win32( t enum_certificatest enum_crls( R+ t AF_INETt SOCK_STREAMt create_connection( t SOL_SOCKETt SO_TYPEs tls-uniques� TLS13-AES-256-GCM-SHA384:TLS13-CHACHA20-POLY1305-SHA256:TLS13-AES-128-GCM-SHA256:ECDH+AESGCM:ECDH+CHACHA20:DH+AESGCM:DH+CHACHA20:ECDH+AES256:DH+AES256:ECDH+AES128:DH+AES:ECDH+HIGH:DH+HIGH:RSA+AESGCM:RSA+AES:RSA+HIGH:!aNULL:!eNULL:!MD5:!3DESs� TLS13-AES-256-GCM-SHA384:TLS13-CHACHA20-POLY1305-SHA256:TLS13-AES-128-GCM-SHA256:ECDH+AESGCM:ECDH+CHACHA20:DH+AESGCM:DH+CHACHA20:ECDH+AES256:DH+AES256:ECDH+AES128:DH+AES:ECDH+HIGH:DH+HIGH:RSA+AESGCM:RSA+AES:RSA+HIGH:!aNULL:!eNULL:!MD5:!DSS:!RC4:!3DESt CertificateErrorc B s e Z RS( ( t __name__t __module__( ( ( s /usr/lib64/python2.7/ssl.pyR7 � s i c C sR g } | s t S| j d � } | d } | d } | j d � } | | k rg t d t | � � � n | s� | j � | j � k S| d k r� | j d � nY | j d � s� | j d � r� | j t j | � � n" | j t j | � j d d � � x$ | D] } | j t j | � � q� Wt j d d j | � d t j � } | j | � S( sh Matching according to RFC 6125, section 6.4.3 http://tools.ietf.org/html/rfc6125#section-6.4.3 t .i i t *s, too many wildcards in certificate DNS name: s [^.]+s xn--s \*s [^.]*s \As \.s \Z( t Falset splitt countR7 t reprt lowert appendR t ret escapet replacet compilet joint IGNORECASEt match( t dnt hostnamet max_wildcardst patst piecest leftmostt remaindert wildcardst fragt pat( ( s /usr/lib64/python2.7/ssl.pyt _dnsname_match� s* " &c C s[ | s t d � � n g } | j d d � } xC | D]; \ } } | d k r4 t | | � r_ d S| j | � q4 q4 W| s� xc | j d d � D]L } xC | D]; \ } } | d k r� t | | � r� d S| j | � q� q� Wq� Wn t | � d k r t d | d j t t | � � f � � n; t | � d k rKt d | | d f � � n t d � � d S( s) Verify that *cert* (in decoded format as returned by SSLSocket.getpeercert()) matches the *hostname*.
