A JavaScript library for securely retrieving targets from the Sigstore [TUF][1]
|
||
|
|
repository.
|
||
|
|
|
||
|
|
## Features
|
||
|
|
|
||
|
|
* Embeds the trutsted root metadata file necessary to bootstrap interaction
|
||
|
|
with the Sigstore TUF repository.
|
||
|
|
* Automatically initializes the local TUF cache for storing metadata and
|
||
|
|
target files.
|
||
|
|
|
||
|
|
## Prerequisites
|
||
|
|
|
||
|
|
- Node.js version >= 14.17.0
|
||
|
|
|
||
|
|
## Installation
|
||
|
|
|
||
|
|
```
|
||
|
|
npm install @sigstore/tuf
|
||
|
|
```
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
const { initTUF } = require('@sigstore/tuf')
|
||
|
|
```
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
import { initTUF } from '@sigstore/tuf'
|
||
|
|
```
|
||
|
|
|
||
|
|
### initTUF([options])
|
||
|
|
Returns a TUF client which can be used to retrieve any target from the Sigstore
|
||
|
|
TUF repository. The local TUF cache will be initialized and the TUF metadata
|
||
|
|
files downloaded from the [remote repository][2] as part of the initialization
|
||
|
|
process.
|
||
|
|
|
||
|
|
* `options` `<Object>`
|
||
|
|
* `mirrorURL` `<string>`: Base URL for the Sigstore TUF repository. Defaults to `'https://tuf-repo-cdn.sigstore.dev'`
|
||
|
|
* `cachePath` `<string>`: Absolute path to the directory to be used for caching downloaded TUF metadata and targets. Defaults to a directory named "sigstore-js" within the platform-specific application data directory.
|
||
|
|
* `rootPath` `<string>`: Path to the initial trust root for the TUF repository. Defaults to the [embedded root](./store/public-good-instance-root.json).
|
||
|
|
|
||
|
|
The `TUF` client object returned from `initTUF` has a single `getTarget`
|
||
|
|
function which takes the name of a target in the Sigstore TUF repository
|
||
|
|
and returns the content of that target.
|
||
|
|
|
||
|
|
### getTrustedRoot([options])
|
||
|
|
Retrieves the most recent version of the "trusted_root.json" target from the
|
||
|
|
Sigstore TUF repository. The format of "trusted_root.json" file is described
|
||
|
|
by the [TrustedRoot][3] protobuf and contains the complete set of trusted
|
||
|
|
verification materials for the Sigstore public-good instance.
|
||
|
|
|
||
|
|
* `options` `<Object>`
|
||
|
|
* `mirrorURL` `<string>`: Base URL for the Sigstore TUF repository. Defaults to `'https://tuf-repo-cdn.sigstore.dev'`
|
||
|
|
* `cachePath` `<string>`: Absolute path to the directory to be used for caching downloaded TUF metadata and targets. Defaults to a directory named "sigstore-js" within the platform-specific application data directory.
|
||
|
|
* `rootPath` `<string>`: Path to the initial trust root for the TUF repository. Defaults to the [embedded root](./store/public-good-instance-root.json).
