# supercrypt
A lightweight JavaScript library for symmetric encryption

## Key features
- optimized for binary / file encryption
- uses crypto standard AES on 128b
- includes HMAC authentication (EtA - Encrypt then Authenticate) for guaranteed message authenticity
- written in ES5, ensuring high browser compatibility
- works with node.js, for developing node.js or browser packages

## Installation
Node.js:
```
npm install supercrypt
```

## Usage
Modular include (using Node.js):
```javascript
var supercrypt = require('supercrypt');
```

Using the library:
```javascript
encryptor = new supercrypt({
    fileSize: 100, //bytes
    saveBlock: function(data, callback) {},
    readBlock: function(size, callback) {},
    progressHandler: function(progressPercentage) {},
    finishHandler: function() {}, //called on success
    errorHandler: function(errCode) {}, //called on error
});

var seedList = [1,2,3,4,5,6,7,8,9,0]; //random array of numbers
encryptor.encrypt('key', seedList);
```

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.

GitHub Actions: Input argument passed back as output

An input argument to this GitHub Action flows into a dangerous sink (such as shell command execution). This could allow a malicious user to inject commands or exploit the action.

GitHub Actions: Input argument flows to dangerous sink

A GitHub context variable (such as issue title, PR description, or comment body) is being exported as an environment variable. These context values are user-controlled and could be exploited by subsequent workflow steps.

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.
