Random Number Generator (RNG)

A random number generator is a system used to generate a set of numbers that cannot be reasonably predicted better than by random chance.

You can use this tool to draw winning numbers for your raffle.

We also have a Random Sequence Generator (RSG).

Mathematics

A real-time random number generated by measuring the quantum fluctuations of a vacuum.

This is obtained from one of two quantum random number servers:

qrng.anu.edu.au
Secure Quantum Communication group,
Centre for Quantum Computing
and Communication Technology,
Department of Quantum Sciences,
Research School of Physics and Engineering,
The Australian National University.

qrng.physik.hu-berlin.de

We use CryptGenRandom within the Microsoft CryptoAPI, known also as:
  • The Cryptographic Application Programming Interface
  • CryptoAPI
  • Microsoft Cryptography API
  • MS-CAPI
  • CAPI
It is a cryptographically secure pseudorandom number generator (CSPRNG).

It is optionally seeded by either a quantum true random seed or a user generated seed.
