A simple fast space-efficient statistically good algorithm for random number generation in JavaScript.

## Installation

```bash
npm install pcg32
```

or

```bash
yarn add pcg32
```

## Usage

```javascript
var PCG32 = require('pcg32')

var seed = 42;
var stream = 54;

var pcg32 = new PCG32(seed, stream);

// Print a radnom number between 0 and 4294967295
console.log(pcg32.random());

// Print a radnom number between 0 and 5
console.log(pcg32.random(6));

// Print 0 or 1
console.log(pcg32.random(2));

An input argument to this GitHub Action is being exported as an environment variable. If a user of this action passes untrusted input, it could be used in an insecure manner by subsequent workflow steps.

What are GitHub Actions taint flows?

GitHub Actions: Input argument exported as environment variable

An input argument to this GitHub Action is being passed back as an output. If a user of this action passes untrusted input, it could be used in an insecure manner by consuming workflows.

A GitHub context variable (such as issue title, PR description, or comment body) is being passed back as an output. These context values are user-controlled and could be exploited by consuming workflows.

GitHub Actions: GitHub context variable passed back as output

A GitHub context variable (such as issue title, PR description, or comment body) flows into a dangerous sink (such as shell command execution). This is a critical security issue that could allow command injection or code execution attacks.

GitHub Actions: GitHub context variable flows to dangerous sink

An environment variable flows into a dangerous sink (such as shell command execution). If this environment variable comes from an untrusted source, it could be exploited to inject commands.
