Documentation
class SignableRepresentation a where Source #
A class of types that have a representation in bytes that can be used for signing and verifying.
Methods
getSignableRepresentation :: a -> ByteString Source #
Instances
| SignableRepresentation ByteString Source # | |
Defined in Cardano.Crypto.Util Methods getSignableRepresentation :: ByteString -> ByteString Source # | |
getRandomWord64 :: MonadRandom m => m Word64 Source #
Simple serialisation used in mock instances
readBinaryWord64 :: ByteString -> Word64 Source #
writeBinaryWord64 :: Word64 -> ByteString Source #
writeBinaryNatural :: Int -> Natural -> ByteString Source #
splitsAt :: [Int] -> ByteString -> [ByteString] Source #
Low level conversions
bytesToNatural :: ByteString -> Natural Source #
Create a Natural out of a ByteString, in big endian.
This is fast enough to use in production.
naturalToBytes :: Int -> Natural -> ByteString Source #
The inverse of bytesToNatural. Note that this is a naive implementation
and only suitable for tests.
ByteString manipulation
slice :: Word -> Word -> ByteString -> ByteString Source #
Base16 conversion
decodeHexByteString :: ByteString -> Int -> Either String ByteString Source #
Decode base16 ByteString, while ensuring expected length.
decodeHexString :: String -> Int -> Either String ByteString Source #
Decode base16 String, while ensuring expected length. Unlike
decodeHexByteString this function expects a '0x' prefix.
