Struct AgentKey 

pub struct AgentKey {
    pub kid: String,
    /* private fields */
}

A P-256 signing key: the agent’s key that L2 binds under cnf and that signs L3a and L3b.

Fields

kid: String

The key id the L2 mandate’s cnf.jwk.kid carries and every L3 header repeats. Chosen at generation; stable for the key’s life.

Implementations

impl AgentKey

pub fn generate() -> Self

Generate a fresh key. The kid is the first 16 hex characters of SHA-256 over the SEC1 compressed point, prefixed vik_.

pub fn from_secret(d: &[u8], kid: impl Into<String>) -> Result<Self, ViError>

Rebuild from the 32-byte private scalar and an explicit kid.

pub fn from_private_jwk(v: &Value) -> Result<Self, ViError>

Import a private JWK (d present). Keeps the JWK’s kid when it has one, else derives the same kid generate would.

pub fn secret_bytes(&self) -> [u8; 32]

The 32-byte private scalar, for sealing at rest.

pub fn public_jwk(&self) -> Jwk

The public JWK with this key’s kid, as a wallet binds it under cnf.

pub fn private_jwk(&self) -> Value

The private JWK (d included). For export to a wallet or HSM only.

pub fn sign(&self, signing_input: &[u8]) -> Vec<u8>

ES256: raw r || s, 64 bytes, deterministic (RFC 6979).

Trait Implementations

impl Clone for AgentKey

fn clone(&self) -> Self

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AgentKey

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
