ghead :: (Data x, Typeable y) => x -> y

byteStringToInteger :: ByteString -> Integer

runTMVar :: TMVar s -> StateT s IO a -> IO a

throwM :: (MonadIO m, Exception e) => e -> m a

modifyTVar :: TVar a -> (a -> a) -> STM ()

type Type = String

Our notion of types: A shown Typeable.

showType :: Typeable a => a -> Type

trapForkIO :: String -> IO () -> IO ThreadId

Logs any unhandled exceptions

rsaEncrypt :: RandomGen g => g -> PublicKey -> ByteString -> (ByteString, g)

Encryption stuff

rsaDecrypt :: PrivateKey -> ByteString -> ByteString

rsaVerify :: PublicKey -> ByteString -> ByteString -> Bool

rsaSign :: PrivateKey -> ByteString -> ByteString

swap :: Ord k => k -> v -> Map k v -> (Maybe v, Map k v)

Swap values in a Map. Returns the old value, if any.

listenTVar :: Eq a => TVar a -> (a -> IO ()) -> IO ThreadId

Executes an action once for each value of the TVar. May skip values if it changes quickly.

adjustWithDefault :: Ord k => a -> (a -> a) -> k -> Map k a -> Map k a
