OpenSSL/Utils.hs:34:23:
    Could not deduce (Num i) arising from a use of `hexByte'
    from the context (Bits i)
      bound by the type signature for toHex :: Bits i => i -> String
      at OpenSSL/Utils.hs:33:10-32
    Possible fix:
      add (Num i) to the context of
        the type signature for toHex :: Bits i => i -> String
    In the first argument of `map', namely `hexByte'
    In the first argument of `(.)', namely `map hexByte'
    In the second argument of `(.)', namely
      `map hexByte . unfoldr step'
