SLSA (pronounced "salsa") is a security framework from source to service, giving anyone working with software a common language for increasing levels of software security and supply chain integrity. It’s how you get from safe enough to being as resilient as possible, at any link in the chain.

Learning about SLSA

See https://slsa.dev to learn about SLSA.

What's in this repo?

The primary content of this repo is the spec/ directory which contains the core SLSA specification and the www/ directory which contains the sources of the slsa.dev website. See the README.md in that directory for instructions on how to build the site.

The spec/ folder on the main branch contains the current Draft specification. The released versions of the spec are found in the same folder but on the corresponding release branch (i.e., releases/v1.0, releases/v1.2, etc.)

This repository also hosts SLSA's main issue tracker, covering the website, specification, and overall project management. Other git repositories within the slsa-framework organization have repo-specific issue trackers.
