The Distribution Paradox: How Sigstore Brings Trust to SBOMs

How do you share an SBOM (the blueprint of your weaknesses) securely with a customer? And how do you cryptographically prove it's genuine? Sigstore is the answer.

An SBOM is in effect a treasure map of your software architecture and any weaknesses. This brings a distribution paradox: you want to be transparent towards your customers, but you don't want this blueprint lying out in the open.

With Sigstore's open-source toolset, developers and build environments can cryptographically sign SBOMs (keyless signing). This lets the customer instantly verify that the file is authentic and came unchanged out of the build pipeline, without complicated key management.
