Evervault Node.js SDK

The Evervault Node.js SDK is a toolkit for encrypting data as it enters your server, and working with Cages. By default, initializing the SDK will result in all outbound HTTPS requests being intercepted and decrypted.

Getting Started

Before starting with the Evervault Node.js SDK, you will need to create an account and a team.

For full installation support, book time here.

Documentation

See the Evervault Node.js SDK documentation.

Installation

Our Node.js SDK is distributed via npm, and can be installed using your preferred package manager.

npm install --save @evervault/sdk

yarn add @evervault/sdk

Setup

To make Evervault available for use in your app:

const Evervault = require('@evervault/sdk');

// Initialize the client with your team's api key
const evervaultClient = new Evervault('<API-KEY>');

// Encrypt your sensitive data
const encrypted = await evervaultClient.encrypt({ ssn: '012-34-5678' });

// Process the encrypted data in a Cage
const result = await evervaultClient.run('<CAGE_NAME>', encrypted);

Reference

The Evervault Node.js SDK exposes three functions.

evervault.encrypt()

evervault.encrypt()encrypts data for use in your Cages. To encrypt data at the server, simply pass an object or string into the evervault.encrypt() function. Store the encrypted data in your database as normal.

async evervault.encrypt(data: Object | String);

Parameter	Type	Description
data	Object or String	Data to be encrypted.

evervault.run()

evervault.run() invokes a Cage with a given payload.

async evervault.run(cageName: String, payload: Object[, options: Object]);

Parameter	Type	Description
cageName	String	Name of the Cage to be run
data	Object	Payload for the Cage
options	Object	Options for the Cage run

Cage Run Options

Options to control how your Cage is run

Option	Type	Default	Description
async	Boolean	false	Run your Cage in async mode. Async Cage runs will be queued for processing.
version	Number	undefined	Specify the version of your Cage to run. By default, the latest version will be run.

Enable outbound interception for specific domains

You may pass in an array of domains which you do want to be intercepted, i.e. requests sent to these domains will be intercepted, and hence will be decrypted. This array is passed in the decryptionDomains option. Wildcards domains are supported.

const evervaultClient = new Evervault('<API-KEY>', {
  decryptionDomains: ['httpbin.org', 'api.acme.com', '*.acme.com'], // requests to these domains will be sent through Relay
});
