Public key as bytes in init #62

Closed zanebeckwith closed 6 years ago

zanebeckwith commented 6 years ago

To work toward avoiding AMCL knowledge in the user, the tpm_context_init function should take its public key input in the well-known x9.62 encoding, and not as an AMCL ECP struct.

This arose during usage of the ecdaa-python wrapper, where we need to create a tpm_context struct but don't have access to AMCL functions for creating the necessary ECP public key point.

To fully avoid AMCL knowledge in the API, we also need to add "add" and "remove" (and serialization) functionality to the revocations struct, but that's TODO.
