    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`.

        Verification flags can be combined by oring them together.

          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.

        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.
