About vault
Encrypt your .env files in the browser — no server, no leaks, no trust required.
EnvVault is a free, open-source web tool that lets developers safely encrypt and share their .env files using military-grade cryptography — entirely inside the browser. Paste your environment variables, set a password, and download a self-contained .envvault file. Anyone with the password and the file can decrypt it back to the original .env — no accounts, no cloud storage, no backend. Under the hood, EnvVault uses PBKDF2 (250,000 iterations, SHA-256) for key derivation and AES-256-GCM for authenticated encryption, powered by the browser's native Web Crypto API. All cryptographic parameters (salt, IV, algorithm, iterations) are embedded in the vault file itself, making it fully self-describing and future-proof. Built for developers who work with secret tokens, database URLs, API keys, and other sensitive environment config that should never be sent over Slack or stored in plain text.
