can you please add a description of the workflow? i.e. a sequence of steps that are taken during local attestation, and the functions that are called? the PR is a bit large, and this will help with understanding all the code that you've added. thanks! |

I wrote up a quick document about the steps and functions calls. I linked it in the original description, but here it is again for convenience: https://drive.google.com/file/d/1EtHdv1WbyuTk4r6OGGWCNuufK6MC6SnA/view?usp=sharing |

The goal of this part is to allow Opaque enclaves to establish a shared, secret key that is not known to any untrusted party (i.e. clients, driver, etc.). This key will be used to encrypt the intermediate results in the Spark-generated DAG (with Opaque operators).
