.. note::
This context enables :data:`VERIFY_X509_STRICT` by default, which
may reject older (pre-:rfc:`5280`) or malformed certificates that the
underlying OpenSSL implementation otherwise would accept. While disabling

ctx = ssl.create_default_context()
ctx.verify_flags &= ~ssl.VERIFY_X509_STRICT
