Repository Service for TUF (RSTUF) is a collection of components that provide services for securing content downloads from tampering between the repository and the client (for example, by an on-path attacker).

RSTUF security properties are achieved by implementing The Update Framework (TUF) as a service.

Repository Service for TUF is platform, artifact, language, and process-flow agnostic.

RSTUF simplifies the adoption of TUF by removing the need to design a repository integration -- RSTUF encapsulates that design.

Repository Service for TUF (RSTUF) is designed to be integrated with existing content delivery solutions -- at the edge or in public/private clouds --alongside current artifact production systems, such as build systems, including; Jenkins, GitHub Actions, GitLab, CircleCI, etc. RSTUF protects downloading, installing, and updating content from arbitrary content repositories, such as a web server, JFrog Artifactory, GitHub packages, etc.

If a user wants to integrate RSTUF into an existing CI/CD pipeline the only requirement is to make a REST API request to RSTUF:

The same can be said when a user wants to integrate RSTUF into an existing distribution platform:

Thanks to the REST API, integrating RSTUF into existing content delivery solutions is straightforward. Furthermore, RSTUF is designed for scalability and can support active repositories with multiple repository workers.

At present, RSTUF implements a streamlined variant of the Python Package Index (PyPI)'s PEP 458 – Secure PyPI downloads with signed repository metadata. In the future, RSTUF will grow to provide additional protections through supporting the end-to-end signing of packages, comparable to PyPI's PEP 480 – Surviving a Compromise of PyPI: End-to-end signing of packages.

How does Repository Service for TUF compare to other solutions?

Rugged: Repository Service for TUF is a collection of services to deploy a scalable and distributed TUF Repository. RSTUF provides an easy interface to integrate (the REST API) and a tool for managing the Metadata Repository (CLI).

PyPI/PEP 458: Repository Service for TUF is a generalization of the design in PEP 458 that can be integrated into a variety of content repository architectures.
