Struct IdentityIsland 

pub struct IdentityIsland { /* private fields */ }

ML-DSA-65 identity deterministically derived from a master seed via HKDF-SHA3-512.

For hardware-backed or enclave-resident keys, implement IdentitySigner directly.

Implementations

impl IdentityIsland

pub fn derive( master: &[u8; 32], deployment: &[u8], context: &[u8], ) -> Result<Self, KernelError>

Derives a key pair from master (secret), deployment, and context.

HKDF info = deployment || ':' || context. Different deployments or contexts yield independent key material from the same master seed.

Returns HkdfExpandFailed if the combined info string exceeds 512 bytes.

Trait Implementations

impl IdentitySigner for IdentityIsland

fn public_key(&self) -> PublicKey<'_>

Returns the public key corresponding to this signer’s signing key.

fn sign_into( &self, payload: &[u8], out: &mut [u8; 3309], ) -> Result<(), KernelError>

Signs payload and writes the SIG_SIZE-byte signature into out.
