keytar

What is keytar?

The keytar npm package is a native module for Node.js that allows you to securely store and retrieve credentials using the operating system's native credential storage mechanisms. It supports macOS, Windows, and Linux, providing a cross-platform solution for managing sensitive information.

What are keytar's main functionalities?

Store a password

This feature allows you to store a password securely in the operating system's credential storage. The `setPassword` method takes three arguments: the service name, the account name, and the password.

const keytar = require('keytar');

async function storePassword() {
  await keytar.setPassword('service', 'account', 'password');
  console.log('Password stored successfully');
}

storePassword();

Retrieve a password

This feature allows you to retrieve a stored password from the operating system's credential storage. The `getPassword` method takes two arguments: the service name and the account name.

const keytar = require('keytar');

async function getPassword() {
  const password = await keytar.getPassword('service', 'account');
  console.log('Retrieved password:', password);
}

getPassword();

Delete a password

This feature allows you to delete a stored password from the operating system's credential storage. The `deletePassword` method takes two arguments: the service name and the account name.

const keytar = require('keytar');

async function deletePassword() {
  const result = await keytar.deletePassword('service', 'account');
  console.log('Password deleted:', result);
}

deletePassword();

Find credentials

This feature allows you to find all credentials associated with a specific service. The `findCredentials` method takes one argument: the service name.

const keytar = require('keytar');

async function findCredentials() {
  const credentials = await keytar.findCredentials('service');
  console.log('Found credentials:', credentials);
}

findCredentials();

README

keytar - Node module to manage system keychain

A native Node module to get, add, replace, and delete passwords in system's keychain. On macOS the passwords are managed by the Keychain, on Linux they are managed by the Secret Service API/libsecret, and on Windows they are managed by Credential Vault.

Installing

npm install keytar

On Linux

Currently this library uses libsecret so you may need to install it before running npm install.

Depending on your distribution, you will need to run the following command:

• Debian/Ubuntu: sudo apt-get install libsecret-1-dev
• Red Hat-based: sudo yum install libsecret-devel
• Arch Linux: sudo pacman -S libsecret

Building

• Clone the repository
• Run npm install
• Run npm test to run the tests
