+# itsdangerous.js
+
+... so better sign this.
+
+Various helpers to pass data to untrusted environments and to get it back safe and sound. Data is cryptographically
+signed to ensure that a token has not been tampered with.
+
+It's possible to customize how data is serialized. Data is compressed as needed. A timestamp can be added and verified
+automatically while loading a token.
+
+> Note: This is an unofficial Node.js port of the Python library
+> [itsdangerous](https://github.com/pallets/itsdangerous).
+
+## Installing
+
+```sh
+npm install itsdangerous.js
+```
+
+## Usage
+
+```js
+import {URLSafeSerializer} from 'itsdangerous.js'
+
+const authSerializer = new URLSafeSerializer({secretKey: 'secret key', salt: 'auth'})
+const token = authSerializer.stringify({id: 5, name: 'itsdangerous'})
+
+console.log(token.toString()) // eyJpZCI6NSwibmFtZSI6Iml0c2Rhbmdlcm91cyJ9.6YP6T0BaO67XP--9UzTrmurXSmg
+
+const data = authSerializer.parse(token)
+console.log(data.name) // itsdangerous
+```
