Discovery into libraries required for a python version of Sign and Verify

[e0d]

There are several libraries that provide critical, low-level functionality that will be necessary for implementing VC Sign and Verify in python. We will need to understand which libraries exist and, ideally, choose ones that are full-featured and well-support.

If we have to implement any of these libraries ourselves, we should not that and consider the ROI for that choice.

The list as we currently understand it is:

• JSON-LD library for parsing, navigating, expanding, and contracting JSON-LD input
• Encryption library that supports the ed25519 algorithm

@GlugovGrGlib This looks promising for ed25519: https://github.com/pyca/pynacl

This looks potentially promising for JSON-LD, though not sure it has everything we need or want.

I am also considering jspybridge as an option https://github.com/extremeheat/JSPyBridge/ I want to do a POC using it, and then provide updates, if it can be used

The discovery was finalized with the decision to use Rust based module DIDKIT - https://openedx.atlassian.net/wiki/spaces/OEPM/pages/3490840577/Verifiable+Credentials+integration+-+Solution+Notes#Signing-Credential
