Struct MessageEnvelope 

pub struct MessageEnvelope {
    pub sender: String,
    pub encrypted_header: String,
    pub ciphertext: String,
}

A ready-to-publish encrypted message: the NIP-44-encrypted header and the double-ratcheted ciphertext, plus the sender DH pubkey the recipient uses to locate the chain.

Fields

sender: String

Sender’s current DH public key (x-only hex).

encrypted_header: String

NIP-44 v2 encrypted, base64 Header JSON.

ciphertext: String

Base64 NIP-44 v2 ciphertext of the message payload.

Implementations

impl MessageEnvelope

pub fn to_event<S: NostrSigner>( &self, signer: &S, created_at: i64, ) -> Result<NostrNote, Nip104Error>

Render this envelope as a signed kind-MESSAGE_EVENT_KIND Nostr event.

signer must be the sender’s current ephemeral keypair (its public key must equal self.sender); the reference implementation signs ratchet messages with that key, and the recipient locates the chain by the event’s pubkey.

Errors

Returns Nip104Error::Signer if signing fails.

pub fn from_event(event: &NostrNote) -> Result<Self, Nip104Error>

Parse and verify a kind-MESSAGE_EVENT_KIND Nostr event into an envelope. The event’s pubkey becomes the sender, its content the ciphertext, and the ["header", …] tag the encrypted header.

Errors

Nip104Error::InvalidHeader if the kind is wrong, the signature is invalid, or the header tag is missing.
