A Go implementation of the in-toto framework for protecting software supply chain integrity through cryptographic verification.
in-toto-golang is a Go implementation of the in-toto framework designed to protect software supply chain integrity. It provides cryptographic verification of each step in the software production process, ensuring that no unauthorized modifications occur between source code and deployment. The implementation focuses on verification for admission controllers and kubectl plugins.
Developers and security engineers building secure software supply chains, particularly those working with Kubernetes admission controllers or needing SPIFFE/SPIRE integration for identity management.
This implementation offers a production-ready, auditable core focused on verification rather than broad feature coverage, making it reliable for critical security applications. Its integration with SPIFFE/SPIRE through X.509 signing provides enhanced identity verification capabilities.

Focuses on a stable, auditable set of core functions for cryptographic verification, explicitly designed for reliable use in admission controllers and kubectl plugins, as stated in the philosophy.
Supports X.509 signing through ITE-7 enhancement, enabling secure identity management with SPIFFE/SPIRE, demonstrated in the integration section with certificate constraints.
Enforces constraints on certificates during verification, such as common names and URIs, with detailed JSON examples in the README to ensure proper authorization.
Tailored for verification in Kubernetes admission controllers, providing focused functionality that aligns with cloud-native security needs, as highlighted in the key features.
Lacks support for GPG keys, which is admitted as not yet supported in the README, limiting compatibility with systems relying on GPG for signing.
Prioritizes core verification over broad functionality, which may require additional development for use cases outside admission controllers or SPIFFE integration.
Requires Docker and SPIRE for full integration demos, as seen in the 'Running the Demo' instructions, adding overhead for initial testing and learning.
