What is Sigstore?
Sigstore is a free, open-source service designed to enhance the security of software supply chains. It provides tools and infrastructure for developers to cryptographically sign software artifacts, such as release files, container images, and binaries. This signing process creates a verifiable record of who built the software and what was included, making it difficult for attackers to tamper with code without detection.
Sigstore aims to make software signing accessible and easy to use for all developers, eliminating the need for complex key management. It integrates with existing CI/CD pipelines and offers transparency logs for immutable, publicly auditable records of all signing events. This ensures that consumers of software can verify the authenticity and integrity of the software they use, mitigating risks like supply chain attacks and unauthorized modifications.
The service is primarily for developers, open-source projects, and organizations that need to secure their software delivery process. By providing a robust and transparent mechanism for software provenance, Sigstore helps build trust in the software ecosystem and reduces the attack surface for malicious actors.

Sigstore FAQ
How does Sigstore enhance software supply chain security?
Sigstore enhances software supply chain security by providing tools for developers to cryptographically sign software artifacts. This signing process creates a verifiable record of the software's origin and contents. It helps consumers verify the authenticity and integrity of the software they use, mitigating risks like supply chain attacks.
Which teams benefit most from using Sigstore?
Developers, open-source projects, and organizations that need to secure their software delivery process benefit most from Sigstore. It provides a robust and transparent mechanism for software provenance, which helps build trust in the software ecosystem. This reduces the attack surface for malicious actors.
How does Sigstore compare to solutions like HashiCorp Vault for software security?
Sigstore focuses specifically on signing and verifying software artifacts to secure the supply chain, making it easy to prove who built software and what was included. HashiCorp Vault, while also a security tool, is primarily designed for secrets management and identity-based security. Sigstore's core function is to provide verifiable and auditable records of software provenance.
Does Sigstore include a free tier?
Sigstore is entirely free to use, as it is an open-source service. There are no paid plans or subscription tiers required to access its features for signing, verifying, and protecting software supply chains. This makes it accessible for all developers and organizations.
What kind of integration is required to use Sigstore?
Sigstore requires integration into existing development workflows and CI/CD pipelines. While it simplifies the signing process, developers need to incorporate its tools and infrastructure into their current processes. This allows for cryptographic signing of release files, container images, and binaries.
Can Sigstore help in verifying the authenticity of container images?
Yes, Sigstore provides tools to cryptographically sign various software artifacts, including container images. This allows for the creation of a verifiable record of the image's origin and contents. Consumers can then use this information to verify the authenticity and integrity of the container images they deploy.
Why is Sigstore considered a relatively new technology?
Sigstore is considered a relatively new technology because it is still gaining widespread adoption in the industry. As an evolving open-source project, its ecosystem and integrations are continually expanding. This means that while functional, its full potential and ubiquity are still developing.
