Litdex.Random
Litdex.Random is continuation from Litdex.Security.RNG. Litdex.Random have different namespace and will become the focus of next development. Litdex.Security.RNG will still available but will not receive any bug fix or any update in the future.
Litdex.Random provide basic random generator function with extra feature.
Litdex.Random have already provide some basic random algorithm, so you can use it immediately rather than implement it yourself. But, still Litdex.Random created with extensibility in mind, so you can implement your own random generator with this library.

Current Version
This package contains:
Currently Litdex.Random support this algorithm:
- GJrand
- JSF
- Middle Square Weyl Sequence
- PCG
- Romu
- Seiran
- SFC (Chris Doty-Humphrey's Chaotic PRNG)
- Shioi
- Shishua
- SplitMix64
- Squares
- Tyche
- Wyrand
- Xoroshiro and Xoshiro
All of the algorithm have passing Practrand or Test01 test. But I've never test it individually, the author who is said that their algorithm past Practrand or Test01.
You can check in this website "PRNG Battle Royale: 47 PRNGs � 9 consoles", the writer have tested some of the algorithm that have been implemented.
How to use
For detailed use, read How to use or Documentation
The simple way to use
// create rng object
var rng = new Xoroshiro128plus();
// get random integer
var randomInt = rng.NextInt();

Warning
For method that generate an arbitary byte array, using method NextBytes
or Fill
.
var rng = new Xoroshiro128plus();
var bytes = rng.NextBytes(10);
Litdex.Random generate the array using multiple uint
or ulong
, each uint
or ulong
will converted into byte array. When converted to byte array, Litdex.Random order the byte based on Little Endian. Then each converted byte array will be concated with other byte array.
