    Importing the backend from cryptography has the side effect of activating
    the osrandom engine. This mutates the global state of OpenSSL in the
    process and causes issues for various programs that use subinterpreters or
    embed Python. By putting the import in this function we can avoid
    triggering this side effect unless _get_backend is called.

    An X.509 store.

    An X.509 store is used to describe a context in which to verify a
    certificate. A description of a context may include a set of certificates
    to trust, a set of certificate revocation lists, verification flags and
    more.

    An X.509 store, being only a description, cannot be used by itself to
    verify a certificate. To carry out the actual verification process, see
    :class:`X509StoreContext`.

        Adds a trusted certificate to this store.

        Adding a certificate with this method adds this certificate as a
        *trusted* certificate.

        :param X509 cert: The certificate to add to this store.

        :raises OpenSSL.crypto.Error: If OpenSSL was unhappy with your

        The certificate revocation lists added to a store will only be used if
        the associated flags are configured to check certificate revocation
        lists.

        Set verification flags to this store.

        Verification flags can be combined by oring them together.

        .. note::

          Setting a verification flag sometimes requires clients to add
          additional information to the store, otherwise a suitable error will
          be raised.

          For example, in setting flags to enable CRL checking a
          suitable CRL must be added to the store otherwise an error will be
          raised.

        .. versionadded:: 16.1.0

        :param int flags: The verification flags to set on this store.
            See :class:`X509StoreFlags` for available constants.

        Let X509Store know where we can find trusted certificates for the
        certificate chain.  Note that the certificates have to be in PEM
        format.

        If *capath* is passed, it must be a directory prepared using the
        ``c_rehash`` tool included with OpenSSL.  Either, but not both, of
        *cafile* or *capath* may be ``None``.

        .. note::

          Both *cafile* and *capath* may be set simultaneously.

          Call this method multiple times to add more than one location.
          For example, CA certificates, and certificate revocation list bundles
          may be passed in *cafile* in subsequent calls to this method.

        Sign the CRL.

        Signing a CRL enables clients to associate the CRL itself with an
        issuer. Before a CRL is meaningful to other OpenSSL functions, it must
        be signed by an issuer.

        This method implicitly sets the issuer's name based on the issuer
        certificate and private key used to sign the CRL.

    Load pkcs12 data from the string *buffer*. If the pkcs12 structure is
    encrypted, a *passphrase* must be included.  The MAC is always
    checked and thus required.

    See also the man page for the C function :py:func:`PKCS12_parse`.

    :param buffer: The buffer the certificate is stored in
    :param passphrase: (Optional) The password to decrypt the PKCS12 lump
    :returns: The PKCS12 object
