Struct Ed25519DidKey 

pub struct Ed25519DidKey { /* private fields */ }

Real key material for a local DID subject.

Holds an Ed25519 signing key (advertised as the DID document’s authentication key) and an independent X25519 static secret (advertised as the key-agreement key).

Implementations

impl Ed25519DidKey

pub fn generate() -> Result<Self, DidError>

Generate a key pair from the operating system RNG.

pub fn from_seed(seed: impl AsRef<[u8]>) -> Self

Derive a key pair deterministically from a seed via SHA-256 expansion.

Only as strong as the seed’s entropy — use generate unless you need reproducible keys (tests, fixtures).

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

Ed25519 public key bytes (the DID document authentication key).

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

X25519 public key bytes (the DID document key-agreement key).

pub fn document(&self, did: Did) -> DidDocument

Build a DID document advertising this key pair’s public halves.
