Shipping an npm CLI Tool Securely to a Specific Customer — Designing the Build, Sign, and Deliver Pipeline

You want a privately developed npm CLI tool used only inside one customer enterprise, never on the public npm registry. It looks like plain packaging, but in practice you must satisfy three things at once: passing the OS security gates (Gatekeeper and SmartScreen), tamper-evident signing, and a distribution network you can control and audit per customer. Targeting macOS and Windows now with Linux ahead, this post designs build, signing, distribution, and supply-chain hardening as a single pipeline.

Hardening npm Publishing with Trusted Publishing — Tokenless OIDC, Staged Publishing, and PR-Merge Releases

After the 2025-2026 npm supply-chain attacks, publishing with a long-lived token is no longer the default. Authenticate with GitHub Actions OIDC Trusted Publishing so there is no publish secret, make CI capable of only staging a package, and keep live promotion as a separate npm MFA step. Restrict the release Environment to the PR merge ref, and automate even the release PR itself. The result is a multi-boundary defense where repository write access alone cannot produce a live npm package.

Obtaining OV/EV Code Signing Certificates from Japan — Eligibility for Companies, Sole Proprietors, and Individuals, with 2026 Pricing

Before "how much does a code signing certificate cost," you have to settle "can I even obtain one." A Japanese company can get one from almost any CA and pick on price, but an individual developer with no registered business is generally not issued one by major CAs, and Microsoft's own cloud signing service excludes Japan geographically. This post leads with eligibility by applicant type and region, then prices, to map out which certificate a Japanese company or a Japan-resident individual can actually obtain in 2026.

Windows Code Signing CI Costs by Monthly Signing Volume — What Real Vendor Binaries Reveal in 2026

When you automate Windows code signing in CI, the yearly bill for SSL.com eSigner, DigiCert KeyLocker, and Azure Key Vault + GlobalSign can differ by several multiples depending on your monthly signing volume. The service that is cheapest at 20 signings per month becomes the most expensive at 1,000. And when you verify what major vendors actually ship with osslsigncode, an operational principle emerges that no price sheet reveals on its own: 'fix the entry, refresh the payload.' This post organizes the 2026 CI cost comparison and the operational patterns readable from real vendor binaries.
