Struct Identity 

pub struct Identity { /* private fields */ }

This machine’s Ed25519 identity: a secrecy-wrapped seed plus the derived public key.

The seed never leaves the SecretBox except transiently to sign or to be persisted to the (0600) keyfile; the fmt::Debug impl redacts it.

Implementations

impl Identity

pub fn generate() -> Res<Self>

Generates a fresh identity from operating-system entropy.

Errors

Returns an error if the OS random source cannot be read or the seed is rejected.

pub fn from_seed(seed: [u8; 32]) -> Res<Self>

Reconstructs an identity from its 32-byte seed.

Errors

Returns an error if the seed is rejected by the signing backend.

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

This identity’s raw 32-byte public key.

pub fn public_key_base64(&self) -> String

This identity’s public key as a URL-safe base64 string, for display and pasting.

pub fn sign(&self, message: &[u8]) -> Res<[u8; 64]>

Signs message (e.g. a server challenge nonce), returning the 64-byte signature.

Errors

Returns an error if the signing key cannot be reconstructed from the seed.

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

Formats the value using the given formatter.
