    Evervault

    Evervault React.js SDK

    The Evervault React.js SDK is a toolkit for encrypting data on the client. Using the Evervault React.js SDK means your customer's data never leaves their device unencrypted.

    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 React.js SDK documentation.

    Installation

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

    npm i @evervault/react

    Initialization

    Once installed, initialize the React.js SDK with your team's unique ID found in the Settings. Use an EvervaultProvider component as a provider for your app.

    import { EvervaultProvider } from "@evervault/react";
    export const App = () => (
      <EvervaultProvider teamId={"<YOUR-TEAM-ID>" appId="<YOUR_APP_ID>"}>
        <ChildComponent />
      </EvervaultProvider>;
    );

    Reference

    The Evervault React.js SDK exposes two functions.

    evervault.encrypt()

    evervault.encrypt() encrypts data for use in your Cages. To encrypt data on the client, simply pass the value into the evervault.encrypt() function. Store the encrypted data in your database as normal. Send it to your API and use our server-side SDKs to forward the data to your Cage.

    async evervault.encrypt(data: Object | Array | String | Number);
    Parameter Type Description
    data Object, Array, String or Number Data to be encrypted.

    Any time you want to encrypt data, simply import useEvervault in your component.

    import React from 'react';
    import { useEvervault } from '@evervault/react';
    
    export const MyComponent = ({ someState }) => {
      const evervault = useEvervault();
      const [encryptedState, setEncryptedState] = React.useState(undefined);
    
      const encryptState = React.useCallback(
        async () => setEncryptedState(await evervault.encrypt(someState)),
        [setEncryptedState, evervault]
      );
    
      React.useEffect(() => encryptState(), [encryptState])
    
      return (
        {encryptedState && <p>encryptedState</p>}
      );
    }

    evervault.inputs()

    evervault.inputs() initializes Evervault Inputs which make it easy to collect encrypted cardholder data in a completely PCI-compliant environment.

    Evervault Inputs are served within an iFrame retrieved directly from Evervault’s PCI-compliant infrastructure, which can reduce your PCI DSS compliance scope to the simplest form (SAQ-A) once integrated correctly.

    Simply pass the id of the element in which the iFrame should be embedded.

    We also support themes so you can customise how Inputs looks in your UI.

    evervault.inputs(id: String, theme: String);
    Parameter Type Description
    id string Id of the element in which the Evervault Inputs iFrame should be embedded
    theme string Optional theme for styling Inputs, currently supported: minimal

    Retrieving card data

    There are two ways of accessing encrypted card data once it has been entered. In each case, a cardData object containing details about the card data your user has entered is returned.

    {
      "card": {
        "type": "visa_credit",
        "number": "ev:encrypted:abc123",
        "cvc": "ev:encrypted:def456",
        "expMonth": "01",
        "expYear": "23"
      },
      "isValid": true,
      "isPotentiallyValid": true,
      "isEmpty": false,
      "error": {
        "type": "invalid_pan",
        "message": "The credit card number you entered was invalid"
      }
    }
    onChange hook

    This option is best when you are looking to handle the card values in realtime, like displaying validation errors as a user is inputting their card data. The callback for the hook is run every time your user updates the card data.

    const evervault = useEvervault();
    const [encryptedData, setEncryptedData] = useState(undefined);
    
    const initEvForm = async () => {
      const encryptedInput = evervault?.input?.generate("encryptedInput");
      encryptedInput?.on("change", async (cardData) => {
        setEncryptedData(cardData);
      });
    
      useEffect(() => {
        initEvForm();
      }, [evervault]);
    };

    getData method

    This option is best when you are looking to retrieve card data occasionally, like when your form is submitted.

    const cardData = await inputs.getData();
