Module tari_crypto::ristretto::serialize

Custom serializers for Ristretto keys

The Dalek libraries only serialize to binary (understandably), but this has 2 yucky implications:

1. Exporting to “human readable” formats like JSON yield crappy looking ‘binary arrays’, e.g. /[12, 223, 65, …/]
2. Reading back from JSON is broken because serde doesn’t read this back as a byte string, but as a seq.

The workaround is to have binary serialization by default, but if a struct is going to be saved in JSON format, then you can override that behaviour with with_serialize, e.g.

  #[derive(Clone, Debug, PartialEq, Serialize, Deserialize)]
  pub struct KeyManager<K: SecretKey, D: Digest> {
      #[serde(serialize_with = "serialise_to_hex", deserialize_with = "secret_from_hex")]
      pub master_key: K,
      pub branch_seed: String,
      pub primary_key_index: usize,
      digest_type: PhantomData<D>,
  }
