I went as far as doing this for the time being, since these are required and 5/6 have only 1 allowable field:
```python
    def create_order(self,
                     name=None,
                     payload_content_type='application/octet-stream',
                     payload_content_encoding='base64',
                     algorithm='aes',
                     bit_length=256,
                     cypher_type='cbc',
                     expiration=None):
```

create_secret() has no defaults though.
