TGBOX: encrypted cloud storage based on Telegram

.. epigraph::

    | ❕ This repository contains a set of classes and functions used to manage TGBOX.
    |       Try the `tgbox-cli <https://github.com/NotStatilko/tgbox-cli>`__  if you're interested in working implementation!

.. code-block:: python

    import tgbox, tgbox.api.sync

    # This two will not work. Get your own at https://my.telegram.org
    API_ID, API_HASH = 1234567, '00000000000000000000000000000000'

    tc = tgbox.api.TelegramClient(api_id=API_ID, api_hash=API_HASH)
    tc.start() # This method will prompt you for Phone, Code & Password

    print(phrase := tgbox.keys.Phrase.generate()) # Your secret Box Phrase
    basekey = tgbox.keys.make_basekey(phrase) # Will Require 1GB of RAM
    box = tgbox.api.make_box(tc, basekey) # Will make Encrypted File Storage

    # Will upload selected file to the RemoteBox, cache information
    # in LocalBox and return the tgbox.api.abstract.BoxFile object
    abbf = box.push(input('File to upload (path): '))

    # Retrieving some info from the BoxFile
    print('File size:', abbf.size, 'bytes')
    print('File name:', abbf.file_name)

    downloaded = abbf.download() # Downloading your file from Remote.
    print(downloaded) # Will print path to downloaded file object

    box.done() # Work is done. Close all connections!

    | ❔ This code block heavily utilize the magic ``tgbox.api.sync`` module and high-level functions
    |       from the ``tgbox.api.abstract`` module for showcase. For actual *Async* code, see `Examples <https://tgbox.readthedocs.io/en/latest/examples.html>`__.

Motivation

The Telegram is beautiful app. Not only by mean of features and Client API, but it's also used to be good in cryptography and secure messaging. In the last years, core and client devs of Telegram mostly work for "social-network features", i.e video chats and message reactions which is OK (until stories, wtf?), but there also can be plenty of "crypto-related" things implemented.

Target

This [unofficial] library targets to be a PoC of encrypted file storage inside the Telegram, and should be used as standalone Python library.

Abstract

We name "encrypted cloud storage" as Box and the API to it as tgbox. The Box splits into the RemoteBox and the LocalBox. They define a basic primitives. You can share your Box and separate Files with other people absolutely secure - only You and someone you want will have decryption key, even through insecure communication canals (e2e <https://en.wikipedia.org/wiki/End-to-end_encryption>__). You can make unlimited amount of Boxes, Upload & Download speed is faster than in official Telegram clients and maximum filesize is around 2GB and around 4GB for Premium users.
