free pseudo random number generator algorithm

Issue 3: When you are generating Random numbers - using your most complex algorithm-, things may look good and things might look random, but are they really? Importance of Random Numbers In other words: other people could figure out the random numbers you used. Given the deterministic nature of the PRNG, this can compromise security unless reseeding is carried out appropriately. Issue 2: Some protocols are such that they can 'leak' some details of the PRNG state. Typical seeds such as current time, number of clock ticks since reboot, process ID or user input, produce only a limited number of random bits. Issue 1: Seeds are crucially important to getting a good random number, and it is difficult to find good seeds.

Produces acceptable randomness (see the test result below), and.

Doesn't rely on Internal Random Number tables,.

DOESN'T use or rely on Randomize and Rnd (for anything),.

Avoids all those duplicate 'random' numbers when using the Randomize and Rnd methods,.

Since I am a software guy, I went for 'an algorithm that mimics the generation of random numbers' or in other words a Pseudo Random Number Generator (PRNG). The best Random Number Generators are hardware based. Personally, I just got too tried of having to deal with the issues appearing from the use of Randomize and Rnd in my VB and my ASP applications and since necessity is the mother of all inventions, I created my own PRNG (Pseudo Random Number Generator). If you run the program again without calling randomize, rnd() will give you the same value every time.

Calling rnd() returns that value and steps you to the next value in the list. Calling randomize() places you at some spot in the table (this is typically based on time of day).

VB's, and hence VBScript's, is a table consisting of 16,777,215 random numbers (this is, coincidentally, one of those magic numbers). This is because languages like VB and several others have a built-in 'random number table'.

The odds are incredible, but still you are facing those same reappearing 'random' numbers. If you have tried to use Randomize and Rnd in your programs, you know what I mean.
