Interface EncodableDigest

public interface EncodableDigest extends EncodableService
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.
