Struct SeedSignerKey 

pub struct SeedSignerKey { /* private fields */ }

SignerKey implementation backed by a curve-tagged seed.

carries DevicePublicKey instead of bare [u8; 32] so callers can’t accidentally drop curve information.

Implementations

impl SeedSignerKey

pub fn new(seed: SecureSeed, public_key: [u8; 32]) -> Self

Create a SignerKey from a seed and pre-computed 32-byte Ed25519 pubkey. Back-compat constructor — prefer SeedSignerKey::new_typed when curve is known.

pub fn new_typed(seed: SecureSeed, public_key: DevicePublicKey) -> Self

Create a curve-tagged SignerKey from a seed + typed public key.

pub fn from_seed(seed: SecureSeed) -> Result<Self, AgentError>

Create a SignerKey by deriving the public key from an Ed25519 seed. Preserved for back-compat; use SeedSignerKey::from_typed_seed for curve-aware construction.

pub fn from_typed_seed(seed: TypedSeed) -> Result<Self, AgentError>

Create a SignerKey from a curve-tagged TypedSeed.

pub fn curve(&self) -> CurveType

Returns the curve of the underlying signing key.

pub fn typed_public_key(&self) -> &DevicePublicKey

Returns a typed view of the public key.

Trait Implementations

impl SignerKey for SeedSignerKey

fn public_key_bytes(&self) -> Vec<u8>

Returns the public key bytes of this key.

fn kind(&self) -> SshAlgorithm

Returns the key kind (i.e., SSH algorithm) of this key.

fn sign(&self, message: &[u8]) -> Result<Vec<u8>, AgentError>

Signs a message and returns the signature bytes.
