WebJun 23, 2015 · 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). If you make them 150 digits (maybe even 100) you're pretty safe from duplicates. Otherwise you'll have to check manually. sand casting process with diagramWebThe 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.
