This project example aims to illustrate the use of the Seald SDK and the react-native-accelerator plugin in a react native application. For more information, please refer to this documentation.

Run the demo

To use the Seald SDK, you will need credentials. Follow this documentation to get your API tokens. In src folder, create a credentials.ts file, with the same structure as credentials.template.ts. File the given template with the values from your dashboard.

yarn install

yarn run android
yarn run ios

Code explanation

import Seald SDK, and accelerator functions:

import SealdSDK from '@seald-io/sdk/react-native/seald-sdk-react-native.bundle.js';
import { encryptString, decryptString, encryptURI, decryptURI } from '@seald-io/react-native-accelerator'

Import SDK credentials

import { apiURL, appId, JWTSharedSecret } from './credentials';

Instantiate SDK, generate registration token, initiate a Seald identity:

const sealdSDK = SealdSDK({appId, apiURL})

// JWTSharedSecret is a secret and should NEVER be sent to the client.
// The license JWT should be provided by your backend, at login/signup.
const signupJWT = await sealdSDK.utils.generateRegistrationJWT(JWTSharedSecret.key, JWTSharedSecret.id, {joinTeam: true})

await sealdSDK.initiateIdentity({signupJWT})

Create an encryption session

const recipients = {} // Current user is added by default. There will be no other recipients
encryptionSession = await sealdSDK.createEncryptionSession(recipients)

Set the SDK instance, and the encryption session instance in app store

setES(es)
setSealdSDK(sdk)

Accelerator functions are used in demo functions:

const encryptedFileUri = await encryptURI(FILE_URI, FILENAME, encryptionSession)
const decryptedFileObject = await decryptURI(FILE_URI, encryptionSession)

const encryptedFile = await encryptString(FILE_CONTENT, FILENAME, encryptionSession)
const clearFileObject = await decryptString(ENCRYPTED_FILE_CONTENT, encryptionSession)
