Rustoken

Rustoken is a Python library written in Rust that can create and decode JWT tokens. This is the first version of the library and it currently supports only the HS256 algorithm.

How to make SECRET-KEY in Rustoken:

from rustoken import secret_key

secret_key = secret_key() # save it to .env file
print(secret_key)

How to make SECRET-KEY on linux:

# 32 bytes (256 bits) base64
openssl rand -base64 32   # outputs a base64 string you can store

# or 64 bytes (512 bits)
openssl rand -base64 64

Usage In Fast-Api:

from rustoken import RustToken

from fastapi import FastAPI, Depends
from sqlalchemy.orm import Session
from . import models, schemas, database

app = FastAPI()


models.Base.metadata.create_all(bind=database.engine)

def get_db():
    db = database.SessionLocal()
    try:
        yield db
    finally:
        db.close()


@app.post("/make-user/", response_model=schemas.UserResponse)
def create_user(user: schemas.UserCreate, db: Session = Depends(get_db)):
    new_user = models.User(username=user.username, email=user.email)
    db.add(new_user)
    db.commit()
    db.refresh(new_user)

    #<------------------------------------------------------->
    jwt = RustToken("MY-SECRET-KEY") # better to use .env file
    access = jwt.create_token(new_user.id, 24 * 60 * 60) # 1 day
    refresh = jwt.create_token(new_user.id, 24 * 60 * 60 * 7) # 7 day exp
    return {"refresh_token": refresh, "access_token": access}

NOTE: The expiration time is in seconds

How to decode Tokens:

    from rustoken import RustToken

    jwt = RustToken("MY-SECRET-KEY") # better to use .env file

    token = "eyJ0eXAiOiJKV1QiLCJhbGciO..."
    try:
        jwt.decode(token)
    except ValueError:
        # if token is expired it return a ValueError
