Struct EncryptedMessage 

pub struct EncryptedMessage {
    pub group_id: GroupId,
    pub message_type: MlsMessageType,
    pub epoch: u64,
    pub ciphertext: Vec<u8>,
    pub sender_id: String,
    pub timestamp_ms: u64,
}

The sealed-envelope types, re-exported so that every path into them keeps working and there is still exactly one definition of each.

They live in offline-protocol-sealed because a leaf node encodes and decodes the same envelope this crate does, and cannot link this crate: this one is built on OpenMLS, which needs std. See ADR 0022. An encrypted MLS message ready for transport.

Fields

group_id: GroupId

The group ID this message belongs to.

message_type: MlsMessageType

Type of MLS message.

epoch: u64

Current epoch when the message was created.

ciphertext: Vec<u8>

Serialized MLS message bytes.

sender_id: String

Sender’s user ID.

timestamp_ms: u64

Timestamp when the message was created.

Implementations

impl EncryptedMessage

pub fn to_base64(&self) -> Result<String, SealedError>

Encodes the encrypted message to base64 for transport.

pub fn from_base64(encoded: &str) -> Result<EncryptedMessage, SealedError>

Decodes an encrypted message from base64.

pub fn to_bytes(&self) -> Vec<u8>

Serializes to a compact binary format, avoiding base64/JSON overhead.

JSON renders ciphertext as an integer array (~3.7x inflation), which is unacceptable for large payloads such as encrypted file chunks.

Wire format (all multi-byte integers are little-endian):

[group_id_len:4][group_id][sender_len:4][sender_id]
[message_type:1][epoch:8][timestamp_ms:8]
[ciphertext_len:4][ciphertext]

pub fn from_bytes(data: &[u8]) -> Result<EncryptedMessage, SealedError>

Deserializes from the compact binary format produced by to_bytes.
