fingerprint0 :: Fingerprint Source

readHexFingerprint :: String -> Fingerprint Source

fingerprintData :: Ptr Word8 -> Int -> IO Fingerprint Source

fingerprintString :: String -> Fingerprint Source

getFileHash :: FilePath -> IO Fingerprint Source

Computes the hash of a given file. This function loops over the handle, running in constant memory.
