data SHACtx

newCtx :: Length -> IO SHACtx

unsafeUpdateCtx :: SHACtx -> ByteString -> IO ()

Heads up: Calling this function after calling finalizeCtx is likely to result in crashes, therefore unsafe.

unsafeFinalizeCtx :: SHACtx -> IO ByteString

After calling this, you must not call either unsafeUpdateCtx or unsafeFinalizeCtx again. (On the same context)

showBSasHex :: ByteString -> String

Converts a ByteString to hexadeximal string format
