Struct Ed25519Identity

pub struct Ed25519Identity { /* private fields */ }

An unchecked, unvalidated Ed25519 key.

This key is an “identity” in the sense that it identifies (up to) one Ed25519 key. It may also represent the identity for a particular entity, such as a relay or an onion service.

This type is distinct from an Ed25519 PublicKey for several reasons:

• We’re storing it in a compact format, whereas the public key implementation might want an expanded form for more efficient key validation.
• This type hasn’t checked whether the bytes here actually are a valid Ed25519 public key.

Implementations

impl Ed25519Identity

pub fn new(id: [u8; 32]) -> Self

Construct a new Ed25519 identity from a 32-byte sequence.

This might or might not actually be a valid Ed25519 public key.

use tor_llcrypto::pk::ed25519::{Ed25519Identity, PublicKey};

let bytes = b"klsadjfkladsfjklsdafkljasdfsdsd!";
let id = Ed25519Identity::new(*bytes);
let pk: Result<PublicKey,_> = (&id).try_into();
assert!(pk.is_ok());

let bytes = b"aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";
let id = Ed25519Identity::new(*bytes);
let pk: Result<PublicKey,_> = (&id).try_into();
assert!(pk.is_err());

pub fn from_bytes(id: &[u8]) -> Option<Self>

If id is of the correct length, wrap it in an Ed25519Identity.

pub fn as_bytes(&self) -> &[u8]

Return a reference to the bytes in this key.
