Description:

paseto 2.0.0

PASETO Tokens for Python

This is an unofficial implementation of
for Python.
PASETO versions supported: v2, v3, and v4
Please note that the v2 token type standard is expected to be deprecated in 2022, so new development should be done ideally on versions 3 or 4.
Installation
pip install paseto

Usage
To create/parse paseto tokens, use the create/parse functions. These will
automatically handle encoding/decoding the JSON payload for you, and validate
claims (currently just the 'exp' expiration registered claim).
import paseto
from paseto.keys.symmetric_key import SymmetricKey
from paseto.protocols.v4 import ProtocolVersion4
my_key = SymmetricKey.generate(protocol=ProtocolVersion4)

# create a paseto token that expires in 5 minutes (300 seconds)
token = paseto.create(
key=my_key,
purpose='local',
claims={'my claims': [1, 2, 3]},
exp_seconds=300
)

parsed = paseto.parse(
key=my_key,
purpose='local',
token=token,
)
print(parsed)
# {'message': {'exp': '2021-10-25T22:43:20-06:00', 'my claims': [1, 2, 3]}, 'footer': None}

You can also make and verify "public" tokens, which are signed but not
encrypted:
import paseto
from paseto.keys.asymmetric_key import AsymmetricSecretKey
from paseto.protocols.v4 import ProtocolVersion4
my_key = AsymmetricSecretKey.generate(protocol=ProtocolVersion4)

# create a paseto token that expires in 5 minutes (300 seconds)
token = paseto.create(
key=my_key,
purpose='public',
claims={'my claims': [1, 2, 3]},
exp_seconds=300
)

parsed = paseto.parse(
key=my_key,
purpose='public',
token=token,
)
print(parsed)
# {'message': {'exp': '2021-10-25T22:43:20-06:00', 'my claims': [1, 2, 3]}, 'footer': None}
