BetterRandom - A C# class to produce random numbers which inherits from the .NET framework's System.Random class and so can be a drop-in replacement for usages of the standard Random class, but which uses the RNGCryptoServiceProvider to generate better (and cryptographically secure) random numbers.
View BetterRandom.cs
using System;
using System.Security.Cryptography;
namespace BetterRandomNumbers
{
// BetterRandom.cs
// This class implements a random number generator that is based off the Windows "Next Generation" cryptographically secure
// random number generator. It inherits from the base Random class, so can be used as a "drop-in" replacement for the
// built-in .NET System.Security.Random class, but providing a superior quality of random numbers.
