Demo for Signature verification

[mpguerra]

Motivation

We want to simulate a simple execution of FROST to show potential FROST implementers how to use the FROST library.

Scope

Build a simple CLI that takes in a message, a signature for the message and a verification key and returns whether the message signature is valid.

Specification

The CLI will use the following input values:

• The message, msg, that was signed
• The final Schnorr signature, (R,z), generated in Demo for Signature generation: Coordinator CLI frost-zcash-demo#48 , and
• The public key, PK
  to run prime_order_verify, to check if the signature is valid.

The CLI will output True if the signature is valid or False if the signature is invalid for the given message. We may optionally wish to ouput a more user friendly message to the terminal in each case.

@conradoplg @natalieesk did we do this?

@conradoplg @natalieesk did we do this?

We didn't, I think we decided it was not important. We might still do it but it doesn't seem a priority...
