JWTSign

Rust jwt signing bindings for python

Usage:

import time
import json

from jwtsign import PyJwtEncoder, PyJwtDecoder

def read_bin(path: str) -> bytes:
    with open(path, "rb") as file:
        return file.read()

claims = {
    "id": "example",
    "exp": int(time.time() + 60),
}

private_key = read_bin("res/private_key.pem")
public_key = read_bin("res/public_key.pem")
encoder = PyJwtEncoder(private_key)
decoder = PyJwtDecoder(public_key, leeway=60)

# Using object encoding
token_claims_obj = encoder.encode_claims_json_obj(claims)
decoded_claims_obj = decoder.decode(token_claims_obj)

# Using serialized object encoding
token_claims_str = encoder.encode_claims_json_str(json.dumps(claims))
decoded_claims_str = decoder.decode(token_claims_str)

Decoder validates expiration time based on UTC with a leeway defined in the PyJwtDecoder::__init__.

Note

If at any point you have your claim as serialized JSON keep in mind that this performs slightly faster than the object as encoding parameter, as the rust code uses python bindings to call json.dumps on the object.
