True Random Number Generator

At, we offer random numbers generated by a true random number generator (TRNG). In contrast to TRNGs, computers produce pseudo-random numbers, which seems random to many applications, but they are not truly random. For many applications, these pseudo-random numbers are not sufficiently random, which have led many researchers to investigate the possibility of creating TRNGs.

To generate truly random numbers, every TRNG needs a physical source of randomness (also called entropy source). In this regard, the RandN's randomness comes from optical devices. By applying proper algorithms, the observed physical randomness transformed into a sequence of truly random bits that can be queried by users.
