TUF Client Example, using python-tuf.

This TUF Client Example implements the following actions:

• Client Initialization
• Target file download

The client can be used against any TUF repository that serves metadata and targets under the same URL (in /metadata/ and /targets/ directories, respectively). The used TUF repository can be set with --url (default repository is "http://127.0.0.1:8001" which is also the default for the repository example).

In one terminal, run the repository example and leave it running:

examples/repository/repo

In another terminal, run the client:

# initialize the client with Trust-On-First-Use
./client tofu

# Then download example files from the repository:
./client download file1.txt

Note that unlike normal repositories, the example repository only exists in memory and is re-generated from scratch at every startup: This means your client needs to run tofu every time you restart the repository application.

# On first use only, initialize the client with Trust-On-First-Use
./client --url https://jku.github.io/tuf-demo tofu

# Then download example files from the repository:
./client --url https://jku.github.io/tuf-demo download demo/succinctly-delegated-1.txt
