# @vltpkg/keychain

The filesystem keychain for `@vltpkg/registry-client`

**[Usage](#usage)**

## Overview

This is a tool to store and retrieve private keys for use in the
`@vltpkg/registry-client`.

## Usage

```js
import { Keychain } from '@vltpkg/keychain'

// define a keychain with a given application scope
const kc = new Keychain('vlt/auth')

// fetch the auth for a given origin, for example.
// will load file on demand when first get() called.
const auth = await kc.get('https://registry.npmjs.org')

// set a value like this
kc.set('https://some-registry.com', 'Bearer newtoken')

// will attempt to save on process end if there are pending
// writes, but only if the file has not been modified since.
// you can also trigger a write explicitly.
await kc.save()
```

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.
