Server Authentication

Pangea SDK allows apps to authenticate users to their backend servers without relying on centralized identity providers. This provides cryptographic proof-of-identity for secure API requests, data access, and user actions.

Client-side

const jwt = await user.createClientAuthorization({
    username: await user.getUsername(),
    foo: "bar"
});
// Securely send the jwt string to your server

Server-side

import { verifyClientAuthorization } from '@tonomy/tonomy-id-sdk'

// receive JWT string from the client
const verifiedUser = await verifyClientAuthorization(jwt);

You can also use the same flow above to send all requests, which adds integrity protection and non-repudiation to all requests to your server.

Why use it?

• Proof-of-Identity for backend actions (e.g., payments, data storage)

• Non-repudiation: Know exactly which user made the request
