Telethon secret chat plugin

Secret chat plugin for telethon

This is still a work in progress so expect more commits to it. Used https://core.telegram.org/api/end-to-end at first but it wasn’t clear enough so I followed their advice and checked one of the implementations that had it https://github.com/danog/MadelineProto so this pluigin is based on daniil’s implementation at its core.

• ☒ Accepting secret chats
• ☒ Creating secret chats
• ☒ Closing secret chats
• ☒ Sending text messages
• ☒ Recieving text messages
• ☒ Uploading/downloading media
• ☒ Dealing with rekeying¹
• ☐ Saving secret chats keys to database²
• ☐ Saving messages to database³
• ☒ Automatic decryption/accepting/finishing

¹ Every 100 messages you need to recreate the auth key.

² Auth keys are saved client sides so if you restart the script you will lose all secret chats you had and can no longer recieve messages from them

³ There is no get_messages function in secret chats so users can’t see old messages.

Examples :

client = TelegramClient(...)

async def replier(event):
 # all events are encrypted by default
 if event.decrypted_event.message and event.decrypted_event.message == "hello":
     await event.reply("hi")


 manager = SecretChatManager(client, auto_accept=True)  # automatically accept new secret chats
 manager.add_secret_event_handler(func=replier) # we can specify the type of the event
 client.run_until_disconnected()

To start a secret chat you can call

manager.start_secret_chat(target)

to use sqlite as a storage session you need to pass an sqlite connection to SecretChatManager

manager = SecretChatManager(client,session=db_conn, auto_accept=True)
# you can also pass client.session from telethon as such
manager = SecretChatManager(client,session=client.session, auto_accept=True)

to manually accept incoming you can do as follow

from telethon_secret_chat import SecretChatManager, SECRET_TYPES
manager = SecretChatManager(client, auto_accept=False)
manager.add_secret_event_handler(event_type=SECRET_TYPES.accept,func=accept_secret_chat_handler)

in your handler you can do the following

await manager.accept_secret_chat(event.chat)
