WebJun 23, 2015 · Never roll your own RNG or Crypto. Use well-known, tested, mature code, and use it exactly as directed. The simplest, well-tested crypto PRNGs are the ones built into your OS: /dev/random on Linux, CryptGenRandom on Windows. The "no duplicates" thing is a problem with small numbers (10 digits). WebThe DRBG produces a sequence of bits from a secret initial value called a seed. A cryptographic DRBG has the additional property that the output is unpredictable given that the seed is not known. A DRBG is sometimes also called a pseudo-random number generator (PRNG) or a deterministic random number generator.
