    Check only the common name in the certificate presented by the peer and

    This is to provide I{something} in the way of hostname verification to
    users who haven't installed C{service_identity}. This check is overly
    strict, relies on a deprecated TLS feature (you're supposed to ignore the
    commonName if the subjectAlternativeName extensions are present, I
    believe), and lots of valid certificates will fail.

dd�Zdd�ZdS)�DistinguishedNameag
    Identify and describe an entity.

    Distinguished names are used to provide a minimal amount of identifying
    information about a certificate issuer or subject.  They are commonly
    created with one or more of the following fields::

        commonName (CN)
        organizationName (O)
        organizationalUnitName (OU)
        localityName (L)
        stateOrProvinceName (ST)
        countryName (C)
        emailAddress

    A L{DistinguishedName} should be constructed using keyword arguments whose
    keys can be any of the field names above (as a native string), and the
    values are either Unicode text which is encodable to ASCII, or L{bytes}
    limited to the ASCII subset. Any fields passed to the constructor will be
    set as attributes, accessible using both their extended name and their
    shortened acronym. The attribute values will be the ASCII-encoded
    bytes. For example::

        >>> dn = DistinguishedName(commonName=b'www.example.com',
        ...                        C='US')
        >>> dn.C
        b'US'
        >>> dn.countryName
        b'US'
        >>> hasattr(dn, "organizationName")
        False

    L{DistinguishedName} instances can also be used as dictionaries; the keys
    are extended name of the fields::

        >>> dn.keys()
        ['countryName', 'commonName']
        >>> dn['countryName']
        b'US'

    A L{PublicKey} is a representation of the public part of a key pair.

    You can't do a whole lot with it aside from comparing it to other
    L{PublicKey} objects.

        L{OpenSSL.crypto.PKey} that does not contain a private key!

        Compute a hash of the underlying PKey object.

        The purpose of this method is to allow you to determine if two

        anything else.

        In versions of Twisted prior to 15.0, C{keyHash} used a technique

    Attempt to discover a set of trusted certificate authority certificates
    (or, in other words: trust roots, or root certificates) whose trust is
    managed and updated by tools outside of Twisted.

    If you are writing any client-side TLS code with Twisted, you should use
    this as the C{trustRoot} argument to L{CertificateOptions
    <twisted.internet.ssl.CertificateOptions>}.

    The result of this function should be like the up-to-date list of
    certificates in a web browser.  When developing code that uses
    C{platformTrust}, you can think of it that way.  However, the choice of
    which certificate authorities to trust is never Twisted's responsibility.
    Unless you're writing a very unusual application or library, it's not your
    code's responsibility either.  The user may use platform-specific tools for
    defining which server certificates should be trusted by programs using TLS.
    The purpose of using this API is to respect that decision as much as
    possible.

    This should be a set of trust settings most appropriate for I{client} TLS
    connections; i.e. those which need to verify a server's authenticity.  You
    should probably use this by default for any client TLS connection that you
    create.  For servers, however, client certificates are typically not
    verified; or, if they are, their verification will depend on a custom,
    application-specific certificate authority.

    @since: 14.0

    @note: Currently, L{platformTrust} depends entirely upon your OpenSSL build
        supporting a set of "L{default verify paths <OpenSSLDefaultPaths>}"
        which correspond to certificate authority trust roots.  Unfortunately,
        whether this is true of your system is both outside of Twisted's
        control and difficult (if not impossible) for Twisted to detect
        automatically.

        Nevertheless, this ought to work as desired by default on:

            - Ubuntu Linux machines with the U{ca-certificates
              <https://launchpad.net/ubuntu/+source/ca-certificates>} package
              installed,

            - macOS when using the system-installed version of OpenSSL (i.e.
              I{not} one installed via MacPorts or Homebrew),

            - any build of OpenSSL which has had certificate authority
              certificates installed into its default verify paths (by default,
              C{/usr/local/ssl/certs} if you've built your own OpenSSL), or

            - any process where the C{SSL_CERT_FILE} environment variable is
              set to the path of a file containing your desired CA certificates
              bundle.

        Hopefully soon, this API will be updated to use more sophisticated
        trust-root discovery mechanisms.  Until then, you can follow tickets in
        the Twisted tracker for progress on this implementation on U{Microsoft
        Windows <https://twistedmatrix.com/trac/ticket/6371>}, U{macOS
        <https://twistedmatrix.com/trac/ticket/6372>}, and U{a fallback for
        other platforms which do not have native trust management tools
        <https://twistedmatrix.com/trac/ticket/6934>}.

    Wrap up an C{info_callback} for pyOpenSSL so that if something goes wrong
    the error is immediately logged and the connection is dropped if possible.

    This wrapper exists because some versions of pyOpenSSL don't handle errors
    from callbacks at I{all}, and those which do write tracebacks directly to
    stderr rather than to a supplied logging system.  This reports unexpected
    errors to the Twisted logging system.

    Also, this terminates the connection immediately if possible because if
    you've got bugs in your verification logic it's much safer to just give up.

            instead, since it provides the same functionality in a less
            error-prone way.

        @param verifyOnce: If True, do not re-verify the certificate on session
            resumption.

        @param enableSingleUseKeys: If L{True}, generate a new key whenever
            ephemeral DH and ECDH parameters are used to prevent small subgroup
            attacks and to ensure perfect forward secrecy.

        @param enableSessions: This allows a shortened handshake to be used
            when a known client reconnects to the same process.  If True,
            enable OpenSSL's session caching.  Note that session caching only
            works on a single Twisted node at once.  Also, it is currently
            somewhat risky due to U{a crashing bug when using OpenSSL 1.1.1

        @param fixBrokenPeers: If True, enable various non-spec protocol fixes
            for broken SSL implementations.  This should be entirely safe,
            according to the OpenSSL documentation, but YMMV.  This option is
            now off by default, because it causes problems with connections
            between peers using OpenSSL 0.9.8a.

        @param enableSessionTickets: If L{True}, enable session ticket
            extension for session resumption per RFC 5077.  Note there is no
            support for controlling session tickets.  This option is off by
            default, as some server implementations don't correctly process

        @param dhParameters: Key generation parameters that are required for
            Diffie-Hellman key exchange.  If this argument is left L{None},

            certificate authorities specified by this object.

            Note that since this option specifies the same information as
            C{caCerts}, C{verify}, and C{requireCertificate}, specifying any of

    the curve, when appropriate, on a new L{OpenSSL.SSL.Context}.

    following based on the provided OpenSSL version and configuration:

        - L{_configureOpenSSL110}

        - L{_configureOpenSSL102}

        - L{_configureOpenSSL101}

        - L{_configureOpenSSL101NoCurves}.
