opentele2-core

The Rust core of opentele2, a Telegram client identity toolkit. The same core runs the Python package (PyPI opentele2) and the Node package (npm opentele2).

• Telegram Desktop 7.3.1 tdata: read and write, passcode-locked folders (Argon2id and scrypt wraps), several accounts per folder, the stored MTP config.
• Sessions: Telethon string sessions and .session files (feature telethon-sqlite), mtcute string sessions (version 3).
• Official API profiles and weighted device catalogs for Android, desktop, iOS, macOS and web.
• initConnection fingerprint validation and the seven consistency checks.
• MTProto client crypto: AES-256-IGE and -CTR, SHA-1, SHA-256, HMAC, PBKDF2, PQ factorisation, gzip and the OS random source.

Synchronous, no network, no unsafe.

    let account = tdata.main_account().expect("folder has an account");
    println!("{}", telethon::StringSession::from_account(account, false)?.encode());
    println!("{}", mtcute::StringSession::from_account(account, false)?.encode());
    let desktop = api::profile(api::Client::Desktop, &Versions::offline());
    println!("{} {}", desktop.device_model, desktop.app_version);
    Ok(())
}

grammers 0.11 sessions are in opentele2-grammers, browser fingerprints in opentele2-browser and live client versions in opentele2-versions.
