Documentation

data CryptoParseError Source #

Error that can happen during parsing of cryptographic primitive types.

Constructors

Instances

Eq CryptoParseError Source #
Instance details Defined in Tezos.Crypto.Util Methods (==) :: CryptoParseError -> CryptoParseError -> Bool # (/=) :: CryptoParseError -> CryptoParseError -> Bool #
Show CryptoParseError Source #
Instance details Defined in Tezos.Crypto.Util Methods showsPrec :: Int -> CryptoParseError -> ShowS # show :: CryptoParseError -> String # showList :: [CryptoParseError] -> ShowS #
Buildable CryptoParseError Source #
Instance details Defined in Tezos.Crypto.Util Methods build :: CryptoParseError -> Builder #

encodeBase58Check :: ByteString -> Text Source #

Encode a bytestring in Base58Check format.

decodeBase58Check :: Text -> Maybe ByteString Source #

Decode a bytestring from Base58Check format.

data B58CheckWithPrefixError Source #

Constructors

B58CheckWithPrefixWrongPrefix ByteString
B58CheckWithPrefixWrongEncoding

Instances

Show B58CheckWithPrefixError Source #
Instance details Defined in Tezos.Crypto.Util Methods showsPrec :: Int -> B58CheckWithPrefixError -> ShowS # show :: B58CheckWithPrefixError -> String # showList :: [B58CheckWithPrefixError] -> ShowS #

decodeBase58CheckWithPrefix :: ByteString -> Text -> Either B58CheckWithPrefixError ByteString Source #

Parse a base58check encoded value expecting some prefix. If the actual prefix matches the expected one, it's stripped of and the resulting payload is returned.

formatImpl :: ByteArrayAccess x => ByteString -> x -> Text Source #

Template for 'format*' functions.

parseImpl :: ByteString -> (ByteString -> Either CryptoParseError res) -> Text -> Either CryptoParseError res Source #

Template for 'parse*' functions.

firstRight :: NonEmpty (Either e a) -> Either e a Source #

Returns first encountered Right in a list. If there are none, returns arbitrary Left. It is useful to implement parsing.

deterministic :: ByteString -> MonadPseudoRandom ChaChaDRG a -> a Source #

Do randomized action using specified seed.
