WebAuthn PRF Example

A lightweight TypeScript library that implements WebAuthn with PRF (Pseudo-Random Function) for secure authentication and encryption. This package allows users to register, authenticate, and encrypt/decrypt messages using derived keys.

Installation

Install the package using npm:

``bash
npm install @adorsys-gis/web-auth-prf
`

Usage

$3

To register a new user, call the handleRegister function:

`javascript
import { handleRegister } from "@adorsys-gis/web-auth-prf";

document.getElementById("registerBtn").addEventListener("click", async () => {
await handleRegister();
});
`

$3

To authenticate an existing user, call the handleAuthenticate function:

`javascript
import { handleAuthenticate } from "@adorsys-gis/web-auth-prf";

document
.getElementById("authenticateBtn")
.addEventListener("click", async () => {
await handleAuthenticate();
});
`

$3

To save and retrieve encrypted messages, use the saveMessage and loadMessages functions:

`javascript
import { saveMessage } from "@adorsys-gis/web-auth-prf";

document
.getElementById("saveMessageBtn")
.addEventListener("click", async () => {
await saveMessage();
});
`

$3

To log out and clear stored credentials and messages, use the handleLogout function:

`javascript
import { handleLogout } from "@adorsys-gis/web-auth-prf";

document.getElementById("logoutBtn").addEventListener("click", async () => {
await handleLogout();
});
``
