UToken (or Unhandleable Token) is a library designed to generate secure tokens with a guarantee of integrity for any type of project. With this project you can add payload and token lifetime.

To install UToken, use the pip package manager:

pip install utokeniz

Here's a short tutorial on how to use UToken in a simple way.

Let's start by creating a token, see the code below:

from utoken import encode

# defining our key
KEY = 'secret-key'

# encoding
my_token = encode({'message': 'Hello World!'}, KEY)
print(my_token)

First we pass as a parameter to utoken.encode() the payload of the token, which must be a dictionary, then we pass the key that will be used to encode the token. After that we have our token in a string returned by the function.

We can add the token expiration time using the expires_in argument of the utoken.encode function. After the maximum time is reached the ExpiredTokenError exception will be thrown. In the example below, the token will expire in 5 minutes:

from utoken import encode
from datetime import timedelta

token = encode({'name': 'Maria'}, 'secret-key', expires_in=timedelta(minutes=5))

Now, let's decode a token. See the code below:

import utoken
from datetime import timedelta

# defining our key
KEY = 'secret-key'

# create a token
token = utoken.encode({'name': 'Maria'}, KEY, expires_in=timedelta(minutes=5))

# decode a token
payload = utoken.decode(token, KEY)
print(payload)

Ready! Our token has been decoded. In utoken.decode() we pass as a parameter the token and the key used in the encoding, simple.
