Description
Synopsis
- replenish :: Int -> [EntropyBackend] -> Ptr Word8 -> IO ()
- data EntropyBackend
- supportedBackends :: [IO (Maybe EntropyBackend)]
- gatherBackend :: EntropyBackend -> Ptr Word8 -> Int -> IO Int
Documentation
replenish :: Int -> [EntropyBackend] -> Ptr Word8 -> IO () Source #
Refill the entropy in a buffer
Call each entropy backend in turn until the buffer has been replenished.
If the buffer cannot be refill after 3 loopings, this will raise an User Error exception
data EntropyBackend Source #
Any Entropy Backend
supportedBackends :: [IO (Maybe EntropyBackend)] Source #
All supported backends
Arguments
| :: EntropyBackend | An open Entropy Backend |
| -> Ptr Word8 | Pointer to a buffer to write to |
| -> Int | number of bytes to write |
| -> IO Int | return the number of bytes actually written |
Gather randomness from an open handle
