Python bindings for murk — encrypted secrets manager

murk-secrets

Python bindings for murk — an encrypted secrets manager for developers.

murk stores encrypted secrets in a single .murk file safe to commit to git. This package lets Python apps read those secrets at runtime.

Prerequisites

You need the murk CLI to create and manage vaults. This package only reads them.

# Install the CLI first
brew tap iicky/murk && brew install murk

# Initialize a vault and add secrets
murk init
murk add DATABASE_URL
murk add API_KEY

Then add the Python package to your project:

pip install murk-secrets

Quick start

# Load your key (created by murk init)
source .env

import murk

# Load the vault (reads MURK_KEY from environment)
vault = murk.load()

# Get a single secret
db_url = vault.get("DATABASE_URL")

# Get all secrets as a dict
secrets = vault.export()

# Dict-style access
api_key = vault["API_KEY"]

API

murk.load(vault_path=".murk") -> Vault

Load and decrypt a murk vault. Reads MURK_KEY or MURK_KEY_FILE from the environment.

murk.get(key, vault_path=".murk") -> str | None

One-liner: load the vault and get a single value.

murk.export_all(vault_path=".murk") -> dict[str, str]

One-liner: load the vault and export all secrets as a dict.

murk.has_key() -> bool

Check if a MURK_KEY is available in the environment.

Vault

Method	Returns	Description
vault.get(key)	str | None	Get a single decrypted value
vault.export()	dict[str, str]	All secrets as a dict
vault.keys()	list[str]	List of key names
vault[key]	str	Dict-style access (raises on missing key)
key in vault	bool	Check if a key exists
len(vault)	int	Number of secrets

Scoped (per-user) overrides are applied automatically — if you have a scoped value for a key, it takes priority over the shared value.

Agent policy

When the loaded key is an agent grant (minted with murk agent grant), the vault's agent policy is enforced on read, the same way the CLI enforces it at murk agent exec: get() and export() raise RuntimeError if the policy forbids a key. Operator keys are unaffected. This makes a policy vault strict from every entry point — though an agent already cannot decrypt out-of-scope secrets at all, since its ephemeral key is not a recipient of them.

Environment

Set one of:

• MURK_KEY — your age secret key directly
• MURK_KEY_FILE — path to your key file (created by murk init)

The easiest setup is source .env in your project directory after running murk init.

Requirements

• Python >= 3.9
• murk CLI installed (to create and manage vaults)
• A .murk vault file in your project (created with murk init)
• MURK_KEY or MURK_KEY_FILE in the environment (created by murk init, loaded via source .env)
