TUF provides a framework for integration of the security properties into new and existing content delivery systems.

While some adoptions integrate TUF by implementing the framework from scratch, others start from either a TUF implementation or from a TUF system.

This page lists open source implementations of TUF which can be used as building blocks for any TUF adoption.

Implementations

TUF implementations provide libraries implementing the primitives and algorithms, such as the detailed client workflow, in the specification.

• python-tuf, the reference implementation
• go-tuf
• tuf-js

Systems

TUF systems build on top of library implementations and provide opinionated signing systems designed for particular use-cases.

• Repository Service for TUF (RSTUF) is a TUF repository designed to integrate into an existing artifact repository with an established storage and delivery system.
• tuf-on-ci is a TUF repository and signing tool designed to operate on a CI system and guide signing events through Git forge workflows.
