Struct SecretState 

pub struct SecretState { /* private fields */ }

Represent a private state contains generated secrets.

Random Secrets

A group of secrets will be created when a new randomness is initialized. The group contains a mask secret and a list of lock secrets. Use mask, unmask and lock to encrypt the ciphertexts from a randomness.

The mask secret should never be shared with others. If all mask secrets are shared, then the whole randomness is possibly revealed. We only share lock secrets When reveal or assign a random item.

Decision Secrets

A decision is an immutable hidden answer from a player. We generate the secret when encrypting the answer. By sharing the secret, the answer is revealed.
