DevVault Secrets Engine
Zero-Knowledge Team .env Secrets & Config Orchestration
Stop committing unencrypted .env files or trusting third-party cloud secret providers. DevVault keeps all environment variables cryptographically sealed with PBKDF2 key derivation and AES-256-GCM authenticated encryption. Inject secrets directly into runtime processes without writing plaintext files to disk.
What it looks like in practice
Up and running in minutes.
Seal your .env file
Run `devvault seal .env.production`. It reads your variables, derives an AES-256-GCM key locally via PBKDF2, encrypts everything, and writes a `.vault` file. The passkey never leaves your machine.
Commit the vault file safely
The encrypted `.vault` file can be safely committed to version control or shared with teammates. Without your passkey, it is mathematically undecryptable.
Inject at runtime
Prefix any command with `devvault run --env production --`. Secrets are decrypted into memory only — never written to disk, never logged, never exposed to the environment filesystem.
Every capability included. Nothing extra to buy.
AES-256-GCM authenticated encryption
Industry-standard authenticated encryption with additional data (AEAD). Any tampering with the vault file is cryptographically detectable before decryption.
PBKDF2 key derivation
Derives encryption keys from your passkey using 100,000 rounds of SHA-256. Makes brute-force and dictionary attacks computationally infeasible.
Zero-write runtime injection
Secrets are decrypted directly into the process memory context. Zero bytes are written to /tmp, /proc, or any filesystem path — no disk forensics possible.
CI/CD compatible
Drop-in for GitHub Actions, GitLab CI, Vercel, Railway, and Docker. Store the encrypted vault in your repo and the passkey in your CI secrets store.
SHA-256 integrity checksums
Every variable block is checksummed individually. DevVault detects and refuses to run if any value has been tampered with, even by a single byte.
Cross-platform binary
Compiles to a single executable for macOS (Apple Silicon + Intel), Linux x64/ARM64, and Windows x64. No runtime dependencies required.
Built for engineers at every scale.
Teams sharing .env files
Stop emailing unencrypted secrets or using risky shared Google Docs. Encrypt once, commit the vault, distribute the passkey through a secure channel.
CI/CD security hardening
Replace plaintext ENV variables in your pipeline config with a single vault file. Only the master passkey needs to be stored in CI secrets management.
Replacing cloud secret providers
Stop paying $15–50/month for HashiCorp Vault, AWS Secrets Manager, or Doppler. DevVault runs locally with stronger zero-knowledge guarantees.
Zero boilerplate. Declarative config.
A single config file or CLI flag is all you need. No dashboards to sign up for, no API keys to manage beyond your own.
