Inofficial Rust Implementation of the Threema Protocols
This will be a library and tools for the Threema Messaging APIs, to make the service compatible with non mobile phone users (e.g. as desktop app, or bridge to Matrix or XMPP). For account registration, the official mobile app or a license purchased in the Threema Store is needed. Please do not abuse this as a replacement for their paid Threema Gateway service.
work in progress.
- split main to library and example(s)
- account import
- threema safe
- id backup
- convert standalone binaries to library
- basic threema transport
- login
- receive/send frames
- decode/encode boxed messages
- connection agent
- reconnect when connection dies
- keep alive echos
- receive event stream
- send messages
- process ack
- keep message while connection is down
- directory API
- lookup public key (
identity/<ID>
) -
identity/fetch_bulk
- registration (POC DONE in python)
- own account information
identity/fetch_priv
- link email / phone
- search contacts
- feature masks
- revocation
- ...
- lookup public key (
- blob API
- streaming support to reduce memory and provide progress
- VOIP signaling: It would be nice to bridge arbitrary webrtc offers/responses, to bridge it to any other network that uses webrtc.
- publish crate, when usable
- publish rustoc
- De-tokio-ize the threema protocol transport (make it usable without massive dependencies and from synchronous code)
Thanks
- to Roland Schilling and Frieder Steinmetz, who presented a great protocol overview at 33C3 in 2016 (Recording and Slides) and did a Go implementation
o3ma
- to Threema for releasing their code as open source in 2020
Usage
When ready, this will be a rust library crate threema_client
and API doc will be there. Also the bunch of experimental binaries can be used.
Currentliy, accounts are saved plaintext json and can be generated with the register/load programs.
Examples / Binaries:
- creating account JSONs:
register.py
Use a license key to register an identityload_safe
: Download and decrypt Threema-Safe Backupload_idbackup
: Decrypt ID-Backup
- blobs:
getblob
get (and optionally delete) a Blobputblob
upload a Blob
connect
: frequently changing test program: connect to account and print messages- planned:
chatwith
: commandline chat with a single peer / group
