Section titled “mtproto_derive_aes_key_iv”fn mtproto_derive_aes_key_iv(py: Python<'_>, auth_key: Vec<u8>, msg_key: Vec<u8>, client_to_server: bool) -> PyResult<(Vec<u8>, Vec<u8>)>Defined in rust/miniproto/src/crypto.rs:172-188
Derives the AES-256 key and IV used by Python mtproto_derive_aes_key_iv.
Returns (key, iv) and validates both fixed-width inputs. Valid inputs total 272 bytes
(auth_key 256 plus msg_key 16), so this wrapper never exceeds the detach threshold and
performs the derivation while holding the GIL.
Arguments
Section titled “Arguments”py: The acquired GIL token retained by this bounded-size operation.auth_key: The 256-byte MTProto authorization key.msg_key: The 16-byte MTProto message key.client_to_server: Selects the directional MTProto key offset.
