DMNO Encrypted Vaults

Install

Install the package:

npm add @dmno/encrypted-vault-plugin

pnpm add @dmno/encrypted-vault-plugin

yarn add @dmno/encrypted-vault-plugin

bun add @dmno/encrypted-vault-plugin

Initialize the plugin

Initialize the plugin in the root, or service if not shared. Note the vault/prod alias, which we can refer to in other services or in the CLI. This is useful if you have multiple vaults.

Also, note the configPath function. This is a helper function that will look up the value of the key that contains the key used to encrypt/decrypt the vault. This is useful for keeping the key out of the codebase. It will need to live in your .env.local file, or in an environment variable.

import { defineDmnoService, configPath } from 'dmno';
import { EncryptedVaultDmnoPlugin, EncryptedVaultTypes } from '@dmno/encrypted-vault-plugin';

const MyProdVault = new EncryptedVaultDmnoPlugin('vault', {
  key: configPath('DMNO_VAULT_KEY'),
});


export default defineDmnoService({
  schema: {
    DMNO_VAULT_KEY: {
      extends: EncryptedVaultTypes.encryptionKey,
      // NOTE - the type itself is already marked as secret
    },
  },
});

If your plugin was initiatized in root and you need to use in a child service, inject the already configured plugin:

import { EncryptedVaultDmnoPlugin } from '@dmno/encrypted-vault-plugin';

const MyVault = EncryptedVaultDmnoPlugin.injectInstance('vault/prod'); // same "instance name" it was created with

Initialize the vault and key

npm exec -- dmno plugin -p vault -- setup

pnpm exec dmno plugin -p vault -- setup

yarn exec -- dmno plugin -p vault -- setup

bun run dmno plugin -p vault -- setup

This will:

detect if the vault is configured but has no key value
detect if vault file is empty/exists
create new a key if needed

Add vault items to your schema

{
  // simple case example
  SUPER_SECRET_ITEM: {
    value: MyProdVault.item(),
  },
  ITEM_WITH_PROD_ONLY_SECRET: {
    value: toggleByNodeEnv({
      _default: 'not-a-secret',
      staging: NonProdVault.item(), // reference to another vault
      production: MyProdVault.item(),
    })
  },
}

Fill the vault with your secrets

Add encrypted values to the vault:

npm exec -- dmno plugin -p vault -- add

pnpm exec dmno plugin -p vault -- add

yarn exec -- dmno plugin -p vault -- add

bun run dmno plugin -p vault -- add

Rotate the vault key

npm exec -- dmno plugin -p vault -- rotate-key

pnpm exec dmno plugin -p vault -- rotate-key

yarn exec -- dmno plugin -p vault -- rotate-key

bun run dmno plugin -p vault -- rotate-key

This will:

generate a new key, and share it, similar to the initial setup
re-encrypts all the values in the vault with the new key

Accessing an existing vault

If you’re joining a project that already has a vault set up, you’ll will need to get the key from a coworker.
