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). http://www.bouncycastle.org/csharp/

WebJan 6, 2015 · $\begingroup$ PRNG encompasses all pseudo random number generators, from the horrible rand call in c, over suitable for simulations but not security ones like the mersenne twister, to the most secure cryptographic PRNG. CSPRNGs are simply the subset of PRNGs which are secure. Every stream cipher, including AES-CTR can act as CSPRNG. … WebMar 15, 2024 · Everyone seems to have missed a bit of a nuance here: Cryptographic algorithms require a number to be mathematically and statistically random over all executions of the algorithm.
