Wire helpers for padded WAProto message payloads and Baileys-style message IDs.

Summary

Types

proto_message()

Functions

decode(binary)

Unpads and deserializes a WAProto message from binary.

encode(message, opts \\ [])

Serializes and adds random WhatsApp XMPP padding to a WAProto message.

generate_message_id(user_id \\ nil, opts \\ [])

Generates a 3EB0... random message ID that WhatsApp Web typically uses.

generate_participant_hash(participants)

Produces the device participant hash indicating which E2E key copies were distributed.

unpad_random_max16(binary)

Strips WAProto padding block, returning only the underlying protobuf.

write_random_pad_max16(binary, opts \\ [])

Pads a binary buffer dynamically using deterministic/cryptographic randomness.
