verifyTelegram 1.0

This Python module securely validates and extracts user data from a URL-encoded string, using HMAC and SHA-256 for data integrity. It features a User class to structure user information and a Data class for validation and data parsing. Ideal for web applications needing secure user authentication and data management, it's easy to integrate and use.

Data Validation and User Extraction Module

This Python module is designed to handle the validation and extraction of user data from a URL-encoded string. It uses HMAC and SHA-256 hashing to ensure data integrity and security. The module provides a simple way to validate input data and parse it into a structured User object.

Requirements

This module requires Python 3.6+ and uses the following standard libraries:

• hmac
• hashlib
• urllib
• json
• dataclasses

Installation

No external libraries are required for this module. Simply include the code in your Python project.

Usage

User Class

The User class is a data class that holds the following information about a user:

• id: The user's unique identifier (integer).
• first_name: The user's first name (string).
• last_name: The user's last name (string).
• username: The user's username (string).
• language_code: The language code of the user (string).
• is_premium: A boolean indicating if the user has a premium account.
• allows_write_to_pm: A boolean indicating if the user allows writing to private messages.

Data Class

The Data class is responsible for validating input data and extracting user information from a URL-encoded string.

Initialization

To create an instance of the Data class, you need to provide a bot token:

data_instance = Data(BOT_TOKEN="your_bot_token_here")

is_valid_data Method

This method checks if the provided data is valid by comparing the generated hash with the initial data hash.

is_valid = data_instance.is_valid_data(INIT_DATA_HASH="your_init_data_hash", DATA_CHECK_STRING="your_data_check_string")

GetData Method

This static method extracts user data from the data check string and returns a User object.

user = Data.GetData(DATA_CHECK_STRING="your_data_check_string")

Example

Here's an example of how to use the module:

BOT_TOKEN = "1231212:sdsadasdsadasd231ec"
INIT_DATA_HASH = "90677c2f2e1326cdb4d5cd781905c375f5397b8f6dbee501487385aa3faf3e0e"
DATA_CHECK_STRING = "auth_date=1721578504&chat_instance=-5432073769796079823&chat_type=private&user=%7B%22id%22%3A6195030789%2C%22first_name%22%3A%22._.%22%2C%22last_name%22%3A%22%22%2C%22username%22%3A%22ksdaskdnc2w%22%2C%22language_code%22%3A%22en%22%2C%22allows_write_to_pm%22%3Atrue%7D"

data_instance = Data(BOT_TOKEN)
if data_instance.is_valid_data(INIT_DATA_HASH, DATA_CHECK_STRING):
    user = Data.GetData(DATA_CHECK_STRING)
    print(f"User {user.first_name} ({user.username}) is authenticated.")
else:
    print("Invalid data provided.")
