<?php // Example of a scalable approach to using Sigstore and Cosign class SigstoreClient { private $sigstoreApiUrl; public function __construct($apiUrl) { $this->sigstoreApiUrl = $apiUrl; } public function signArtifact($artifact) { // Implement signing logic using Sigstore // Make API calls to Sigstore to sign the artifact } public function verifyArtifact($artifact) { // Implement verification logic using Sigstore // Check if the artifact is signed correctly } } // Use Cosign to manage container image signing function signContainerImage($imageName) { // Command to sign a container image exec("cosign sign $imageName"); } // Usage $sigstoreClient = new SigstoreClient('https://sigstore.dev/api'); $sigstoreClient->signArtifact('example-artifact'); signContainerImage('example-image:latest'); ?>
