Usage

sighash-2-4:

import Crypto.MAC.SigHash (hash)
import qualified Data.ByteString.Char8 as B

k0 = 0xaaaaaaaaaaaaaaaa
k1 = 0xbbbbbbbbbbbbbbbb
tag = hash (SigKey k0 k1) (B.pack "my text to hash")

sighash-c-d:

import Crypto.MAC.SigHash (hash)
import qualified Data.ByteString.Char8 as B

k0 = 0xaaaaaaaaaaaaaaaa
k1 = 0xbbbbbbbbbbbbbbbb
