Examples

---

Repository

---

See the basic_repository.go example which demonstrates how to manually create and maintain repository metadata using the low-level Metadata API.

The example highlights the following functionality supported by the metadata API:

• creation of top-level metadata
• target file handling
• consistent snapshots
• support a mixture of key types - ED25519, RSA and ECDSA
• top-level delegation and signing thresholds
• metadata verification
• target delegation
• in-band and out-of-band metadata signing
• writing and reading metadata files
• root key rotation

Client

---

There's also a client_example.go which demonstrates how to implement a client using the updater package.

• it uses https://jku.github.io/tuf-demo, a live TUF repository hosted on GitHub
• shows an example of how to initialize a client
• shows an example of how to download a target file
• the repository is based on python-tuf so it also highlights the interoperability between the two implementations

Multi-repository client

---

There's a client_example.go which demonstrates how to implement a multi-repository client using the multirepo package which implements TAP 4 - Multiple repository consensus on entrusted targets. The example consists of the following:

• The map.json along with the root files for each repository are distributed via a trusted repository used for initialization
  • The metadata, these target files and the script generating them are located in the examples/multirepo/repository folder
• These files are then used to bootstrap the multi-repository TUF client
• Shows the API provided by the multirepo package

CLI tools

---

The following CLIs are experimental replacements of the CLI tools provided by the go-tuf package. At some point these will be moved to a separate repository.

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

• tuf - Not implemented
