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_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 N) namedtuple)Enum)OPENSSL_VERSION_NUMBEROPENSSL_VERSION_INFOOPENSSL_VERSION) _SSLContext)SSLErrorSSLZeroReturnErrorSSLWantReadErrorSSLWantWriteErrorSSLSyscallError SSLEOFError) CERT_NONE CERT_OPTIONAL CERT_REQUIRED)VERIFY_DEFAULTVERIFY_CRL_CHECK_LEAFVERIFY_CRL_CHECK_CHAINVERIFY_X509_STRICT)txt2objnid2obj) RAND_statusRAND_egdRAND_add RAND_bytesRAND_pseudo_bytescCsCx<ttD].}|j|r tt|t||j|n|S)zCreate a SSLContext object with default settings.
