public interface EncodableDigest

Encodable digests allow you to download an encoded copy of their internal state. This is useful for the situation where you need to generate a signature on an external device and it allows for "sign with last round", so a copy of the internal state of the digest, plus the last few blocks of the message are all that needs to be sent, rather than the entire message.
