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://cwe.mitre.org/data/definitions/338.html WebFor many modes, this means using a CSPRNG (cryptographically secure pseudo random number generator). For modes that require a nonce, then the initialization vector (IV) does not need a CSPRNG. In all cases, the IV should never be used twice for a fixed key. Always use authenticated encryption instead of just encryption.
