micro-verifier-challenge

A tiny Node.js microservice to generate a cryptographically-random verifier and challenge (for React Native authentication flows).

This can help if you are required to follow the Auth0 Authorization Code Grant Flow with PKCE with Expo/React Native (as Node.js' crypto module is not available in RN).

Deployment

Deploy to now

Usage

GET https://your-url.now.sh/

You will get the data in the following format:

{
  "verifier": "MAIYIPi-3BJWxzaV1cXPZGnfMZdgbWuwxThvUdmFHQE",
  "challenge": "eWbxKj7OZAr8RDaGSHN_bWvxpDBrS30lGW53DHzuUT8"
}

Keep in mind that this process is a compromise and should usually be handled locally. It's probably secure enough, but keep in mind that this microservice should only be accessed through HTTPS.

Development

git clone git@github.com:fabe/micro-verifier-challenge.git
yarn
yarn dev

The server will be listening at localhost:3000.
