remix-webcrypto-cookie-session
This library was created as a drop-in replacement for Remix's built-in
createCookieSessionStorage
method, but with support for encrypting sessions
using the simple-secure-webcrypto
encryption library.
Features
✅ Only 1 package dependency outside of Remix.
✅ Uses Web Crypto APIs = Works on browser platforms like Cloudflare Workers.
✅ Secure defaults; uses AES-GCM (authenticated encryption) with a 256 bit key.
✅ Written in TypeScript.
Usage
Install via your package manager:
bun install remix-webcrypto-cookie-session
Then import createWebCryptoCookieSessionStorage
in place of createCookieSessionStorage
in your code.
Please refer to the official documentation for more information:
https://remix.run/docs/en/main/utils/sessions
How does it work?
Remix signs and verifies cookies. Instead, we use the encrypt/decrypt methods from the simple-secure-webcrypto package.
