Implementations

impl Ed25519PublicKey

pub const LENGTH: usize = 32usize

The length of an ed25519 public key in bytes.

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

pub fn generate<R>(rng: R) -> Self

where R: RngCore + CryptoRng,

Available on crate feature rand only.

pub const fn into_inner(self) -> [u8; 32]

Return the underlying byte array of an Ed25519PublicKey.

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

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

pub fn from_bytes<T: AsRef<[u8]>>(bytes: T) -> Result<Self, TryFromSliceError>

impl Ed25519PublicKey

pub fn scheme(&self) -> SignatureScheme

Return the flag for this signature scheme

impl Ed25519PublicKey

pub fn derive_address(&self) -> Address

Available on crate feature hash only.

Derive an Address from this Public Key

An Address can be derived from an Ed25519PublicKey by hashing the bytes of the public key prefixed with the Ed25519 SignatureScheme flag (0x00).

hash( 0x00 || 32-byte ed25519 public key)

use sui_sdk_types::Address;
use sui_sdk_types::Ed25519PublicKey;
use sui_sdk_types::hash::Hasher;

let public_key_bytes = [0; 32];
let mut hasher = Hasher::new();
hasher.update([0x00]); // The SignatureScheme flag for Ed25519 is `0`
hasher.update(public_key_bytes);
let address = Address::new(hasher.finalize().into_inner());
println!("Address: {}", address);

let public_key = Ed25519PublicKey::new(public_key_bytes);
assert_eq!(address, public_key.derive_address());
