.. function:: enum_cert_store(store_name, cert_type='certificate')
Retrieve certificates from Windows' system cert store. *store_name* may be
one of ``CA``, ``ROOT`` or ``MY``. Windows may provide additional cert
stores, too. *cert_type* is either ``certificate`` for X.509 certificates
or ``crl`` for X.509 certificate revocation lists.
The function returns a list of (bytes, encoding_type) tuples. The
encoding_type flag can be interpreted with :const:`X509_ASN_ENCODING` or
:const:`PKCS_7_ASN_ENCODING`.
Availability: Windows.
