API Locker

API Locker is a secure, encrypted credential vault designed for developers. It streamlines the management of LLM API keys, service API keys, and OAuth credentials by storing them in one place and allowing injection into any command at runtime. With robust features like AES-256-GCM encryption, device-based master tokens, audit logs, rotating/revoking credentials, and MCP integration for AI agents, it eliminates the need for vulnerable .env files and lets teams securely share, rotate, and audit secrets with ease.
