Random byte generation

3 declarations
valuerandBytes
  1. :: Int

    the number of bytes requested

  2. -> IO ByteString
#

Return a bytestring consisting of the given number of strongly random bytes

valueprandBytes
  1. :: Int

    the number of bytes requested

  2. -> IO ByteString
#

Return a bytestring consisting of the given number of pseudo random bytes

valueadd
  1. :: ByteString

    random data to be added to the pool

  2. -> Int

    the number of bits of entropy in the first argument

  3. -> IO ()
#

Add data to the entropy pool. It's safe to add sensitive information (e.g. user passwords etc) to the pool. Also, adding data with an entropy of 0 can never hurt.
