WebCryptographically Secure Pseudo-Random Number Generators (CSPRNG) are designed to produce a much higher quality of randomness (more strictly, a greater amount of entropy), making them safe to use for security-sensitive functionality. 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).
