  A Mersenne Twister Class - The Code Project - C++ / MFC
The Mersenne Twister(MT) is a pseudorandom number generator (PRNG) developed by Makoto Matsumoto and Takuji Nishimura[1][2] during 1996-1997.
The Mersenne Twister is generally considered to be fast, small and provides equal distribution.

  Mersenne twister
The Mersenne twister is a pseudorandom number generator that was developed in 1997 by Makoto Matsumoto (松本 眞) and Takuji Nishimura (西村 拓士).
There are two variants of the algorithm, the newer and more commonly utilised one being the Mersenne Twister MT 19937.
This period, incidentally, explains the origin of the name: it is a Mersenne prime, and some of the guarantees of the algorithm depend on internal use of Mersenne primes.

 Reference.com/Encyclopedia/Mersenne twister
The Mersenne twister is a pseudorandom number generator developed in 1997 by Makoto Matsumoto (松本 眞) and Takuji Nishimura (西村 拓士) that is based on a matrix linear recurrence over a finite binary field
The Mersenne Twister algorithm is a twisted generalised feedback shift register (twisted GFSR, or TGFSR) of rational normal form (TGFSR(R)), with state bit reflection and tempering.
As like TGFSR(R), the Mersenne Twister is cascaded with a tempering transform to compensate for the reduced dimensionality of equidistribution (because of the choice of A being in the rational normal form), which is equivalent to the transformation A = R → A = T

 The Mersenne Twister
It was the development of this method by the developers of the Mersenne Twister that made the creation of such a large maximum-period shift register possible.
The invention of the Mersenne Twister was preceded by the development, by the same inventors, of a related algorithm with an array of 25 rather than 624 elements, called TT800.
The first of the Mersenne primes to be discovered by computer were 2^521-1, 2^607-1, 2^1279-1, 2^2203-1, and 2^2281-1, all discovered by Raphael M. Robinson on the Standards Western Automatic Computer (SWAC) a computer with a small Williams Tube random-access memory and a larger auxilliary memory on a magnetic drum.

One of the appealing aspects of the Mersenne Twister is its use of binary operations -- as opposed to time-consuming multiplication -- for generating numbers.
I've implemented the Mersenne Twister in C++ and Fortran 95; while there already exist versions of the algorithm in those languages, none of thesemet my criteria, and some of the implementations contain language and logic errors.

 Integrity at Bugsys Club
With increased exposure over the past few years, The Mersenne Twister PRNG is increasingly accepted as the random number generator of choice for all statistical simulations and generative modeling, especially because it overcomes the shortcomings of prior pseudorandom number generators (PRNG).
This is valid because the Mersenne Twister PRNG is statistically random in all the bits of its output.
Because BugsysClub Poker uses the Mersenne Twister PRNG and the incremental Knuth shuffle (with a range function that is free of bias) you are guaranteed that you will receive a 'true' shuffle for any given hand.

 PHP: mt_rand - Manual
Mersenne Twister has an ENORMOUS amount of internal state - 4992 bits, bigger than practically any cipher's key length.
Running the output of Mersenne Twister through an unkeyed secure hash is NOT a good way to make it secure, because it'll still have a relatively small internal state which, if recovered, would allow reproduction of the keystream.
A better idea would be to encrypt the output with a keyed encryption algorithm - but if you were going to do that, you wouldn't need a psuedorandom number generator at all, because a counter would be just as good.
