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`.

suitable CRL must be added to the store otherwise an error will be
raised.
