tuf-client CLI

---

Overview

---

tuf-client is a CLI tool that implements the client workflow specified by The Update Framework (TUF) specification.

The tuf-client can be used to query for available targets and to download them in a secure manner.

All downloaded files are verified by signed metadata.

The CLI provides three commands:

• tuf-client init - Initialize the client with trusted root.json metadata
• tuf-client get - Download a target file
• tuf-client reset - Resets the local environment. Warning: this deletes both the metadata and download folders and all of their contents

All commands except reset require the URL of the TUF repository passed as a flag via --url/u

Run tuf-client help from the command line to get more detailed usage information.
