What would you prefer ?

At the moment, i'm inclined to someday move cryptohash apis to be similar to crypto-api. i.e. from a result type being a bytestring to an opaque type with serialize/show instance.

Why? I don't actually need the hash object for anything, usually. All I need is the ByteString, and then I need to learn how to use the cereal package to get it...

So talking purely about convenience, I would prefer hash :: HashType -> InputData -> ByteString. That would probably not be extensible enough, so I'm not sure how to optimally do it.

You could use 'hash :: Hash h => Proxy h -> ByteString -> ByteString'. where 'data Proxy a = Proxy'. Defined for you in the 'tagged' package. Antoine
