[Haskell-cafe] [web-devel] [ANNOUNCE] First release of crypto-conduit

[Aristid Breitkreuz]

To use the hash, I have to convert it to a ByteString, and then I
suddenly have lost all this safety. I don't really see how there is
any real safety gained.

That said, just exposing a direct method of getting to that ByteString
without cereal (as Thomas proposed) would be an improvement.
