 [Litdex.Security.RNG](https://github.com/Shiroechi/Litdex.Security.RNG) have already provide some basic random algorithm, so you can use it immediately rather than implement it yourself. But, still [Litdex.Security.RNG](https://github.com/Shiroechi/Litdex.Security.RNG) created with extensibility in mind, so you can implement your own *random generator* with this [library](https://github.com/Shiroechi/Litdex.Security.RNG).
