TGBOX: encrypted cloud storage based on Telegram

❕ This repository contains a set of classes and functions used to manage TGBOX.

Try the tgbox-cli if you're interested in working implementation!

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.

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). 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.
