Struct PairingResponse 

pub struct PairingResponse {
    pub short_code: String,
    pub device_ephemeral_pubkey: String,
    pub device_signing_pubkey: String,
    pub curve: CurveTag,
    pub device_did: String,
    pub signature: String,
    pub device_name: Option<String>,
}

A response to a pairing request from the responding device.

The curve field carries the device’s signing curve in-band, so verifiers never infer curve from pubkey byte length (a silent-correctness hazard — see docs/architecture/cryptography.md → Wire-format Curve Tagging). The serialized value is "ed25519" or "p256".

Fields

short_code: String

device_ephemeral_pubkey: String

device_signing_pubkey: String

curve: CurveTag

Curve tag for device_signing_pubkey / signature. Absent → defaults to P256 per the approved Wire-format Curve Tagging rule.

device_did: String

signature: String

device_name: Option<String>

Implementations

impl PairingResponse

pub fn create( now: DateTime<Utc>, token: &PairingToken, device_seed: &TypedSeed, device_pubkey: &[u8], device_did: String, device_name: Option<String>, ) -> Result<(PairingResponse, Zeroizing<[u8; 32]>), ProtocolError>

Create a new pairing response (responder side).

The device’s curve flows through the typed seed — no byte-length guessing. The emitted curve field records the signer’s curve so verifiers read it off the wire instead of inferring from pubkey length.

Args:

• now - Current time for expiry checking
• token - The pairing token from the initiating device
• device_seed - Typed signing seed (curve carried in-band)
• device_pubkey - The responding device’s public key (length matches curve)
• device_did - The responding device’s DID string
• device_name - Optional friendly name for the device

pub fn verify( &self, now: DateTime<Utc>, token: &PairingToken, ) -> Result<(), ProtocolError>

Verify the response’s signature using the curve tag carried on the wire.

Curve dispatch reads self.curve directly — never inferred from pubkey byte length. See docs/architecture/cryptography.md → Wire-format Curve Tagging.

pub fn device_ephemeral_pubkey_bytes(&self) -> Result<Vec<u8>, ProtocolError>

Decode the device’s ephemeral P-256 ECDH public key from base64url.

pub fn device_signing_pubkey_bytes(&self) -> Result<Vec<u8>, ProtocolError>
