Crate wechat_protocol 

Native transport and numbered WeChat protocol codecs.

This library does not launch or load the official client. All peer responses pass pinned MMTLS signature and record authentication before business decode. Network methods are blocking; async services must use a blocking worker.

Modules

business

Business encryption is separate from authenticated MMTLS records.

contact_sync

Linux 4.1.13.26 contact stream (CGI8674). This stream has its own rs_config/sync_11 cursor; the message SyncKey is only request context.

crypto

file_upload

File-upload message reservation. This authenticated request can affect the account’s message state; callers must persist its receipt and never retry an uncertain response automatically.

media

Bounded native CDN transport. This uses the observed HTTP carrier on port 443, not HTTPS. Media encryption and advertised size/digests are checked separately.

media_send

Final media-message metadata. CDN upload and message submission are separate steps; persist source bytes, generated keys and intent before either step.

mmtls

Fresh pinned MMTLS handshake and authenticated shortlink exchange.

protobuf

Bounded numbered protobuf primitives. Unknown fields and full u64 values survive.

push

Persistent authenticated incoming notifications. The outer longlink command is distinct from the encrypted business CGI: heartbeat 238/518, sync 121/138.

quote_send

Quoted app-message metadata. Callers resolve the selected message and persist this reference and the final XML before submitting a send attempt.

silk

Bounded independent SILK SDK wrapper. Public source/license pins are under vendor/silk; no WeChat codec library is linked or loaded.

wire

Typed numbered business messages for the supported native profile.

Structs

AccountState

Accepted credentials. Serialize only into the service’s encrypted state vault.

AuthSnapshot

Raw accepted auth sections, retained only inside the encrypted account state. The update mask describes native application gates; presence alone does not mean an optional section changed active account credentials.

Functions

contact_notification_request

Direct contact writes use the official full-contact oplog shape. Fetch a current record first; change only the mute bit and preserve all other bytes.

contact_pinning_requests

Ordinary Linux pin/unpin copies the complete contact, changes primary bit 0x800, and sends ModContact through oplog2. The secondary mask is a uint64. A folded group is removed from its message box in a preceding oplog74 step.

controlled_contact_fields

Extract only the proved field-control IDs. Version ordering is deliberately not guessed: callers preserve these fields and retain the unresolved update.

decode_group_detail

decode_group_inventory

decode_group_mutation

group_detail_request

group_inventory_request

group_mutation_requests

Steps are separate requests. An uncertain step must stop the entire flow. A known cleanup rejection can be retained while a later quit is attempted.

is_retryable_login_poll_error

Polling an issued login challenge is repeatable. This does not authorize retrying QR creation, credential exchange, sends or rejected authentication.

login_lan_error_reason

observed_created_group

Recover a valid create identity even when another success field is malformed. This is evidence for review, never permission to repeat the creation.
