WebA version of the Mersenne Twister available in many programming languages, MT19937, has an impressive period of 219937 -1. Sequences with too short a period can be observed, recorded, and reused by an attacker. Sequences with long periods force the adversary to select alternate attack methods. WebMersenne Twister is an implementation that is used by standard python library. You can see it in random.py file in your python distribution. On my system (Ubuntu 9.10) it is in /usr/lib/python2.6, on Windows it should be in C:\Python26\Lib. The actual Mersenne Twister code is not in random.py, however; random.py refers to a C library for the ...
