It's Dangerous

... 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.


Install and update using pip:

pip install -U ItsDangerous

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"})

# 3i2Uke3sIRnDG0riZD6OoqckqC72VJ9SBIu-vAf_XlwNHnt7dLEClT0JA

data = auth_s.loads(token)
# itsdangerous
