Random Labs provides tools for obtaining and manipulating strong random numbers and to generate passwords and lotto random numbers.


Random numbers acquired with this software fall in 2 categories:


Numbers in this category are retrieved from an on online source at http://www.random.org.
Random.org uses atmospheric noise to produce true random numbers.
The rate of production at about 1.8 MB per hour is not very high, but above other web sources we were able to find. This means that we must not abuse the site resources with this software and a few measures have been taken, namely:
1- You must register the software in order to use it to retrieve data from Random.org. Your email address is sent as User-Agent during the connection. Random.org logs User-Agents and is able to block any persona non-grata.
2- An ad hoc download limit of 16384 bytes per day has been established. When you generate passwords or numbers for lotto games selecting the Random.org option, the software will download more bytes than required. The unused bytes are added to a first in-first out Pool of true random numbers. You can use this Pool to generate passwords and numbers for lotto games. The Pool, when exists, is used as well to generate the seed for the Mersenne Twister PRNG. With the usage, the Pool decreases because values withdrawn are removed from the Pool.


Random Labs includes 2 of the most strong CSPRNG:
1- CryptoMT was developed by Makoto Matsumoto and Takuji Nishimura, authors of the well known Mersenne Twister PRNG. CryptoMT is based on Mersenne Twister (MT), a PRNG with a period of 219937-1. Despite its gigantic period, MT is unsuitable for cryptographic purposes. The reason is simple, it is possible to determine all future states of the generator from the state the generator had at any given time, and either 624 32-bit outputs, or 19,937 one-bit outputs are sufficient to provide that state. CryptoMT works on the output of MT in such a way that there is no way to reconstruct the original sequence of values. In addition, our version of MT is initialized with a seed array of 8 dwords, each dword taken from the Pool (if exists) of true random numbers. Except for the most paranoid cases, CryptoMT can be used as a substitute for a TRNG for all sorts of applications involving random numbers.
2- CryptoAPI is a Microsoft API (application programming interface) that provides cryptography related services, including the generation of cryptographic quality pseudo random numbers. For some people, security related developments with the seal of Microsoft are to be regarded with a grain of salt, so if you do not trust Microsoft then use the CryptoMT instead. Some entropy is gathered from the PC system and used for calling the CryptoAPI, this is not strictly necessary according to Microsoft but provides an additional random seed.
