## Interface EncodableDigest

- All Known Implementing Classes:
    LongDigest, SHA1Digest, SHA224Digest, SHA256Digest, SHA384Digest, SHA512Digest, SHA512tDigest

      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.
