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:
A - True Random Numbers
Numbers in this category
are retrieved from an on online source at
http://www.random.org.
You can visit this if you have access to the internet via
O2 or any other company. If you are using a fast speed internet connection, you will find it much quicker to access.
Random.org uses atmospheric noise to produce true random numbers. The rate of
production of random numbers from atmospheric noise is not very high, but above
other web sources we were able to find. The owner of the website has taken
measures to prevent abuse of the random generator resource, namely the maximum
number of downloadable random bits is 1,000,000 in a single day from each IP
address and the recharging is done at a daily rate of 200,000 bits. This is more
than enough for most purposes. .
B- Cryptographically
Secure Pseudo-Random Number Generators (CSPRNG)
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 2
19937-1.
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.
