Lockbox

Lockbox (also referred to as vaultbox) is an encrypted secrets management tool for Next.js projects, allowing developers to securely store, retrieve, and rotate environment secrets within their code repository—no external secret vault required. It leverages Node.js's built-in crypto module and provides both a CLI and programmatic API for convenience. Lockbox is particularly useful for teams needing versioned, encrypted secrets in environments where serverless deployments and CI/CD pipelines are used.
