PyCrypto v1.9.alpha5 Release Notes 

  •     * Many randpool changes.  RandomPool now has a
      randomize(N:int) method that can be called to get N
      bytes of entropy for the pool (N defaults to 0,
      which 'fills up' the pool's entropy) KeyboardRandom
      overloads this method.

    * Added src/winrand.c for Crypto.Util.winrandom and
      now use winrandom for _randomize if possible.
      (Calls Windows CryptoAPI CryptGenRandom)

    * Several additional places for stirring the pool,
      capturing inter-event entropy when reading/writing,
      stirring before and after saves.

    * RandomPool.add_event now returns the number of
      estimated bits of added entropy, rather than the
      pool entropy itself (since the pool entropy is
      capped at the number of bits in the pool)

    * Moved termios code from KeyboardRandomPool into a
      KeyboardEntry class, provided a version for Windows
      using msvcrt.

    * Fix randpool.py crash on machines with poor timer resolution.
      (Reported by Mark Moraes and others.)

    * If the GNU GMP library is available, two C extensions will be 
      compiled to speed up RSA and DSA operations.  (Contributed by 
      Paul Swartz.)

    * DES3 with a 24-byte key was broken; now fixed.  
  (Patch by Philippe Frycia.)
