The Linux Foundation, BastionZero and Docker have announced OpenPubkey as a Linux Foundation open source project. To coincide with the launch of OpenPubkey, BastionZero is announcing the integration of OpenPubkey for Docker container signing, to help secure the open source software ecosystem with zero-trust passwordless authentication.
“The Linux Foundation is proud to host the OpenPubkey Project,” said Jim Zemlin, Executive Director of the Linux Foundation. “We believe this initiative will play a pivotal role in strengthening the security of the open source software community. We encourage developers and organizations to join this collaborative effort in enhancing software supply chain security.”
The OpenPubkey protocol was developed as part of BastionZero’s secure infrastructure access product. OpenPubkey enables users to securely and accurately bind cryptographic keys to users and workloads by turning an OpenID Connect Identity Provider (IdP) into a Certificate Authority (CA). With the rollout of this integration, Docker users can enhance software supply chain security.
This new cryptographic protocol empowers developers to build out software supply chain or security applications. OpenPubkey augments OpenID Connect to enable workloads and users to sign artifacts under their OpenID identity. These keys can be used to cryptographically sign statements, enabling applications such as secure remote access or software supply chain security features such as signed builds, deployments, and code commits.
“We introduced OpenPubkey as its own standalone protocol to make it easy and secure to use digital signatures with OpenID Connect,” said Ethan Heilman, co-founder and CTO of BastionZero. “We are excited to partner with Docker to offer its community of software developers and open source contributors a simple and convenient way for users, service accounts, machines, or workloads to create digital signatures using their identity.”
