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
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
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.
