Struct AgentIdentity 

pub struct AgentIdentity { /* private fields */ }

Implementations

impl AgentIdentity

pub fn generate() -> Self

Generate a fresh Ed25519 keypair using OS CSPRNG.

pub fn save(&self, dir: &Path) -> Result<(), IdentityError>

Write both halves of the keypair to the given directory. Private key is mode 0600 on Unix.

pub fn load(dir: &Path) -> Result<Self, IdentityError>

Load both halves from the given directory. Prefers the private key (since we can derive pubkey from it); but also validates that a present identity.pub matches.

pub fn signing_key(&self) -> &SigningKey

pub fn sign_bytes(&self, msg: &[u8]) -> [u8; 64]

Sign msg with the Ed25519 private key and return the raw 64-byte signature. Callers that only have a &AgentIdentity (and therefore cannot import ed25519_dalek::Signer themselves) should use this instead of calling signing_key().sign() directly.

pub fn verifying_key(&self) -> VerifyingKey

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

pub fn pubkey_text(&self) -> String

pub fn public_key_multibase(&self) -> String

Alias for pubkey_text() — returns the verifying key as multibase base58btc (z-prefixed string), matching the bridge_pubkey_multibase field used in signed envelopes.

pub fn to_x25519_static_secret(&self) -> StaticSecret

Derive the X25519 static secret usable by Noise XK.

Ed25519 and X25519 both use Curve25519 underneath; the Ed25519 SigningKey scalar maps directly to an X25519 StaticSecret. ed25519-dalek 2.x exposes to_scalar_bytes() for exactly this.

Trait Implementations
