ItsDangerous

... 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.

A Simple Example

Here's how you could generate a token for transmitting a user's id and name between web requests.

from itsdangerous import URLSafeSerializer auth_s = URLSafeSerializer("secret key", "auth") token = auth_s.dumps({"id": 5, "name": "itsdangerous"}) print(token) # eyJpZCI6NSwibmFtZSI6Iml0c2Rhbmdlcm91cyJ9.6YP6T0BaO67XP--9UzTrmurXSmg data = auth_s.loads(token) print(data["name"]) # itsdangerous
