miniproto_native::mtproto::mtproto_encode_message

Provenance

• Crate: miniproto_native
• Rust visibility: restricted
• Source: rust/miniproto/src/mtproto.rs
• Python exposure: miniproto._native.mtproto_encode_message (confirmed from adjacent PyO3 attributes)

Signature

fn mtproto_encode_message(py: _, auth_key: _, server_salt: u64, session_id: u64, msg_id: i64, seq_no: i32, body: _, client_to_server: bool, padding: _) -> _

Arguments

• py: The acquired GIL token used only to detach large native work.
• auth_key: The 256-byte authorization key used to encrypt, but not serialize, the envelope.
• server_salt: The salt serialized at the start of the inner envelope.
• session_id: The session identifier serialized in the inner envelope.
• msg_id: The MTProto message identifier serialized in the inner envelope.
• seq_no: The MTProto sequence number serialized in the inner envelope.
• body: Four-byte-aligned application bytes serialized before the padding.
• client_to_server: Selects the directional MTProto key schedule.
• padding: Optional explicit padding; None requests operating-system random padding.

mtproto_encode_message

fn mtproto_encode_message(py: Python<'_>, auth_key: Vec<u8>, server_salt: u64, session_id: u64, msg_id: i64, seq_no: i32, body: Vec<u8>, client_to_server: bool, padding: Option<Vec<u8>>) -> PyResult<Vec<u8>>

Defined in rust/miniproto/src/mtproto.rs:114-138

Encodes one encrypted MTProto envelope as Python mtproto_encode_message.

The salt, session/message identifiers, sequence number, body length, body, and padding form the inner envelope; auth_key encrypts it but is not itself serialized in that envelope. client_to_server chooses MTProto’s directional key offset; optional padding replaces random padding. Returns auth-key-id/message-key/ciphertext concatenated in wire order, or ValueError for invalid key, body, or padding. For large byte inputs it releases the GIL while performing the native work.

Arguments

• py: The acquired GIL token used only to detach large native work.
• auth_key: The 256-byte authorization key used to encrypt, but not serialize, the envelope.
• server_salt: The salt serialized at the start of the inner envelope.
• session_id: The session identifier serialized in the inner envelope.
• msg_id: The MTProto message identifier serialized in the inner envelope.
• seq_no: The MTProto sequence number serialized in the inner envelope.
• body: Four-byte-aligned application bytes serialized before the padding.
• client_to_server: Selects the directional MTProto key schedule.
• padding: Optional explicit padding; None requests operating-system random padding.
