1Password Secrets Engine for HashiCorp Vault

This is a custom secrets engine for HashiCorp Vault. This plugin uses the 1Password Connect API to allow HashiCorp Vault to interact with items in 1Password accounts by accessing 1Password Connect Server.

Prerequisites

• A basic understanding of HashiCorp Vault (see What is Vault?)
• A HashiCorp Vault server (see Installing Vault)

  Note

  This guide also includes quick start instructions for running a Vault server in dev mode to evaluate this plugin.

• HashiCorp Vault CLI installed on your device (see Install Vault)
• 1Password Connect Server deployed on your infrastructure (see Get started with a 1Password Secrets Automation workflow)
• Go (if you want to build the plugin from source)

Getting started: Get or build the plugin binary

Download the release for your HashiCorp Vault server's architecture, extract the binary, and move it to the plugin directory for your Vault server. For example, for a Vault server running on an AMD64 Linux machine:

# Download the AMD64 release for Linux
wget https://github.com/1Password/vault-plugin-secrets-onepassword/releases/download/v1.0.0/vault-plugin-secrets-onepassword_1.0.0_linux_amd64.zip
# Unzip the release archive
unzip ./vault-plugin-secrets-onepassword_1.0.0_linux_amd64.zip
# Create a plugin directory
mkdir -p ./vault/plugins
# Move the binary to the plugin directory and rename to op-connect
mv ./vault-plugin-secrets-onepassword_v1.0.0 ./vault/plugins/op-connect

Or, you can build the plugin from source. For example:

# Clone this repository
git clone https://github.com/1Password/vault-plugin-secrets-onepassword.git
# Build the binary
go build -o ../vault/plugins/op-connect -C ./vault-plugin-secrets-onepassword ./main.go

Quick start (for evaluation)

You can start HashiCorp Vault server in development mode to demonstrate and evaluate the 1Password secrets engine. In this configuration, Vault starts unsealed, and you do not need to register the plugin.

vault server -dev -dev-root-token-id=root -dev-plugin-dir=./vault/plugins -log-level=debug

Warning

Running Vault in devlopment mode is useful for evaluating the plugin, but should not be used in production.

Connect to the Vault server in a new terminal to enable the secrets engine and use it.

Full installation

Configure and start the Vault server

Write out the configuration file for the Vault server. For example:

cat > ./vault/server.hcl << EOF
plugin_directory = "$(pwd)/vault/plugins"
api_addr         = "http://127.0.0.1:8200"

storage "inmem" {}

listener "tcp" {
  address     = "127.0.0.1:8200"
  tls_disable = "true"
}
EOF

Note

You must set plugin_directory to point to the folder with your custom secrets engine and api_addr for the plugin to communicate with Vault. The Vault instance stores everything in memory and runs locally.

Start the Vault server with this configuration file:

vault server -config=./vault/server.hcl

Connect to the Vault server in a new terminal.

Register the plugin to Vault

Initialize and unseal Vault:

# Set VAULT_ADDR to connect to the local Vault server
export VAULT_ADDR='http://127.0.0.1:8200'
# Initialize Vault
vault operator init
# Unseal Vault with the unseal key
vault operator unseal

Calculate the SHA256 checksum of the plugin binary. For example, on Linux:

SHA256_CHECKSUM=$(sha256sum ./vault/plugins/op-connect | cut -d ' ' -f1)

Or, on macOS:

SHA256_CHECKSUM=$(shasum -a 256 .vault/plugins/op-connect | cut -d ' ' -f1)

Register the plugin to the catalog for the Vault server:

vault plugin register -sha256=$SHA256_CHECKSUM secret op-connect

Enable and configure the plugin

Enable the op-connect secrets engine at the op/ path:

vault secrets enable --path="op" op-connect

Note

You will need to provide the URL for your 1Password Connect Server and your Connect access token for the next step(s).

Write the configuration data to access your Connect server to op/config in a single commmand (assuming the OP_CONNECT_ variables have been set):

vault write op/config \
  op_connect_host=$OP_CONNECT_HOST \
  op_connect_token=$OP_CONNECT_TOKEN

Or, create a JSON file with your 1Password Connect Server details. For example, save the following as op-connect-config.json:

{
    "op_connect_host": "https://op-connect.example.com:8443/",
    "op_connect_token": "your_access_token"
}

Write the data to the op/config path using this file to configure the secrets engine to access 1Password Connect Server.

vault write op/config @op-connect-config.json

Usage

Environment variables

• OP_CONNECT_TOKEN: (required if op_connect_token is not set in configuration): The API token created to be used to connect with the 1Password Connect API.

Commands

Note

When specipfying vault name or item title in the path, if multiple 1Password vaults or items have the same respective name or title, the action will be performed on the oldest vault or item. Item titles or vault names that include white space characters cannot be used (use UUID instead).

List vaults

Returns vault name and UUID for vaults accessible by the configured Connect access token:

vault list op/vaults

List items

Returns item title and UUID for items stored in the specified 1Password vault:

vault list op/vaults/<vault_name_or_uuid>

Read item

Returns item data for the specified item:

vault read op/vaults/<vault_name_or_uuid>/items/<item_title_or_uuid>

Create item

Create an item from a JSON file (see Details for creating and updating items for more information on the JSON schema):

vault write op/vaults/<vault_name_or_uuid>/items @some_json_file.json

Update item

Update a specified item using a JSON file (see Details for creating and updating items for more information on the JSON schema):

vault write op/vaults/<vault_id_or_name>/items/<item_title_or_uuid> @some_json_file.json

Delete item

Delete a specific item:

vault delete op/vaults/<vault_id_or_name>/items/<item_title_or_uuid>

Vault Enterprise namespaces

The 1Password secrets engine supports Vault Enterprise namespaces (see Vault Enterprise Namespaces for more information). If you are using namespaces, the secrets engine must be enabled for each namespace.

Use -namespace to enable the plugin for each namespace. For example:

vault secrets enable -namespace=ns_example op

The plugin also requires configuration in the namespace. Write the configuration in a single command:

vault write -namespace=ns_example op/config \
  op_connect_host=$OP_CONNECT_HOST \
  op_connect_token=$OP_CONNECT_TOKEN

Or, create a file for the configuration and write the contents to the path (see Enable and configure the plugin above for an example file):

vault write -namespace=ns_example op/config @op-connect-config.json
