Initialize TokenManager with a secret and TTL, create a token from a dict, then verify it.

from fastokens import TokenManager import os secret = os.environ.get('FASTOKENS_SECRET', 'my-secret-key') tm = TokenManager(secret=secret, token_ttl=600) # 10 minutes token = tm.create(data={'user_id': 42}) print('Token:', token) data = tm.verify(token) print('Verified data:', data)

Debug

Known issues

breakingThe 'TokenManager' class was renamed from 'Token' in version 0.2.0. Code using 'from fastokens import Token' will fail.

fix

Replace 'Token' with 'TokenManager' in imports and instantiation.

affects: >=0.2.0

gotchaThe 'secret' parameter must be at least 32 bytes. A short secret will raise a ValueError.

fix

Ensure secret is at least 32 characters long, or use a secret generated by os.urandom(32).

affects: all

deprecatedThe 'data' parameter to create() must be a dict. Passing a string or int (as in some examples) is deprecated and will be removed in a future release.

fix

Always wrap non-dict values in a dict, e.g., create(data={'value': 'some_string'}).

affects: <0.3.0
