ownlock 0.1.4

Lightweight secrets manager — encrypted vault, env injection, stdout redaction. No Docker, no server, no account.

ownlock

Lightweight secrets manager — encrypted local vault, .env injection, stdout redaction.

No Docker. No server. No account. Just pip install ownlock.

---

Quick start

pip install ownlock
ownlock init

Have a plaintext .env? Run ownlock auto to import secrets and rewrite the file to use vault().

Otherwise: set a secret, add one line to .env, then run your app:

ownlock set api-key
# Add to .env: MY_APP_KEY=vault("api-key")
ownlock run -- python app.py

---

Guided setup (ownlock auto)

ownlock auto discovers .env and common variants (.env.local, etc.), lets you choose which file and keys to import, then optionally rewrites the file so matching keys use vault("..."). After that you can use ownlock run -- your-command without editing .env by hand.

ownlock auto

For CI or non-interactive use:

ownlock auto -f .env --yes

---

Initialize a vault

Command	Effect
ownlock init	Project vault at ./.ownlock/vault.db. First run also creates the global vault and stores the passphrase in the keyring.
ownlock init --global	Global vault only at ~/.ownlock/vault.db (passphrase in keyring).

ownlock init
# or global only:
ownlock init --global

---

Store, list, delete

ownlock set my-secret
ownlock set api-key=your-value
ownlock set database-url --env production
ownlock list
ownlock get my-secret
ownlock delete my-secret

set and import overwrite any existing value for the same key (and env).

---

Which vault is used?

Situation	Vault used
Inside a directory with .ownlock/vault.db (or a parent)	Project vault
No project vault found	Global vault
--global	Global vault
--project	Project vault at current directory

Commands that accept --global / --project: set, get, list, delete, import, scan. run and export read vault references from your .env file.

---

.env format

Use vault("name") for secrets; they are resolved when you run commands.

API_KEY=vault("api-key")
DATABASE_URL=vault("database-url")
SUPABASE_SERVICE_KEY=vault("supabase-service-key", env="production")

To force the global vault: vault("name", global=true).

---

Run and export

ownlock run -- python app.py
ownlock run -f .env.local -- python app.py
ownlock export --format docker

get and export print secrets to stdout. Use only in trusted environments; prefer ownlock run to inject secrets into a process without printing them.

---

Import, rewrite-env, scan

ownlock import secrets.env
ownlock rewrite-env -f .env
ownlock scan .

---

Command reference

Command	Description
ownlock init	Create project vault (first run also creates global + keyring)
ownlock init --global	Create global vault only
ownlock set KEY / KEY=VALUE	Store secret
ownlock get KEY	Print decrypted value
ownlock list	List secret names
ownlock delete KEY	Remove a secret
ownlock run -- CMD	Resolve .env, inject secrets, redact stdout
ownlock export	Print resolved KEY=VALUE pairs
ownlock import FILE	Bulk import from plaintext .env
ownlock rewrite-env	Rewrite env file to use vault()
ownlock auto	Guided import + rewrite
ownlock scan DIR	Scan for leaked secret values

Add --global or --project to set, get, list, delete, import, scan to override vault selection.

How it works

• Secrets are encrypted with AES-256-GCM before storage.
• Key derivation: PBKDF2-HMAC-SHA256 (200,000 iterations).
• Passphrase is stored in the system keyring when you use init (global or first project init).
• ownlock run resolves vault() in .env, injects env vars, and redacts secret values from stdout/stderr. No network; everything stays local.

---

Security

• Encryption: Each secret is encrypted with AES-256-GCM; the vault stores ciphertext only.
• Passphrase: Required to decrypt; keep it safe. Keyring avoids typing it every time.
• get / export: Both print secrets to stdout. Use in trusted environments only; prefer ownlock run to inject without printing.
• Overwrite: set and import overwrite existing values for the same key (and env); no append.
• File permissions: Restrict permissions on ~/.ownlock/ and .ownlock/. Project init adds .ownlock/ to .gitignore.
