Crate hermes_tdata 

Pure Rust parser for Telegram Desktop tdata folders. Converts tdata to grammers sessions.

Low-level binary parser requiring direct byte indexing, arithmetic for offsets, and integer type conversions.

Features

• Parse tdata folders from Telegram Desktop
• Extract authorization keys (auth_key) and datacenter IDs
• Convert to grammers session format
• Support for password-protected tdata (Local Passcode)
• Zero Python dependencies

Example

use hermes_tdata::TDesktop;

fn main() -> Result<(), hermes_tdata::Error> {
    // Load tdata from default location
    let tdesktop = TDesktop::from_path("/path/to/tdata")?;
     
    // Get the main account's session
    if let Some(account) = tdesktop.main_account() {
        let session = account.to_grammers_session()?;
        println!("DC ID: {}", account.dc_id());
    }
     
    Ok(())
}
