Haskell Crypto.Hash.SHA256 Output

I'm new to Haskell so forgive me for not understanding the basics.

When using the Crypto.Hash.SHA256 to hash the result is something like below.

\159\252\170M\NAK\221\189S\n\191{\197y\t\USUx\143\&3\249\198K}]'\195\nU\154\SI3\199

Can anyone explain what the hell it is I'm looking at?

You're looking at the binary representation of the hash. You're probably used to seeing the hexadecimal representation. To get that, import Data.ByteString.Builder and call toLazyByteString . byteStringHex on it. With the hash in your question, the hexadecimal representation will be 9ffcaa4d15ddbd530abf7bc579091f55788f33f9c64b7d5d27c30a559a0f33c7.
