In-Toto

in-toto Attestation Framework

The in-toto Attestation Framework provides a specification for generating verifiable claims about any aspect of how a piece of software is produced. It defines a fixed lightweight Statement structure with a subject and predicate, and a set of standard predicate types covering common use cases such as SLSA provenance. A future version of the in-toto specification will incorporate this framework as the primary mechanism to express supply chain claims.
