  11. def hashData(hashAlgorithm: HashAlgorithm, source: Source[ByteString, _])(implicit mat: Materializer): Future[Array[Byte]]

    Permalink

    Hash a stream of bytes and return a Future of the hash data.

    Hash a stream of bytes and return a Future of the hash data.

    The overhead of materializing a stream graph makes this much more expensive than just calling the HashAlgorithm directly if the data involved is small. This should be used only for relatively large, infrequent activities. (The primary use case for a StreamHash is to use StreamHash.hashingSink when you're already running a graph.)

  12. def hashingSink(hashAlgorithm: HashAlgorithm): Sink[ByteString, Future[Array[Byte]]]

    Permalink

    A graph akka.stream.scaladsl.Sink that takes in bytes and materializes a hash.
